ACTE On C++ an operation is a mathematical calculation involving zero or more input values (called operands) that produces a new value (called an output value). The specific operation to be performed is denoted by a construct (typically a symbol or pair of symbols) called an operator. Enroll Now with us ACTE C & C++ Classroom & Online Training Course
It is true that you can use almost any language at the back-end, for instance, Google uses C++, Java and Python (along with Go). For low-level data processing, C++ fits the best, for background jobs like updating user's friend recommendations, Java is a good option. C++ allows procedural programming for intensive functions of CPU and provide control over hardware, which it is widely used in developing different games or in gaming engines. C++ mainly used in developing the suites of a game tool.
Future of C and C++, Not only it is a fundamental language but its permissive nature allows the user to manage program memory as it offers the feature of dynamic memory allocation which makes it much faster than any other language. Today, every computer literate person is aware of the term “C/C++ Programming”. Scope of Variables in C++ In general, the scope defined as the extent up to which something can worked with. In programming also the scope of a variable defined as the extent of the program code within which the variable can we accessed, declared, or worked with it.
The Demand for C/C++ in the Market But, it is also important to note that most of the developers know how to code in C and C++. It is the minimum requirement for any programmer to know C/C++ programming to hire. Hence, it is safe to say that C/C++ is the prerequisite of all other languages. In conclusion, C++ in 2020 will continue to remain in high demand owing to its performance, reliability, and the wide variety of contexts in which it can used.

Moreover, we have a very active placement cell that provides 100% placement assistance to our students. The cell also contributes by training students in mock interviews and discussions even after the course completion.
Yes, it is a bright field; there are bright prospects and various avenues in C and C++ programming for candidates with extensive knowledge. If you are not aware of the career in C/C++ Programming, then you have come to the right place. It is also important to note that most of the developers know how to code in C and C++. It is the minimum requirement for any programmer to know C/C++ programming to hire. In India, the pay scale of a C and C++ programmer varies from two lakhs per annum to 30 lakhs per annum. For a novice, who simply did a 2-3 months certification course of C programming is likely to hired by a small-scale organization.
As we know both C and C++ are programming languages and used for application development. The main difference between both these languages is C is a procedural programming language and does not support classes and objects, while C++ is a combination of both procedural and object-oriented programming languages. C and C++ share a similar syntax, this is the aspect of both languages that are most similar. ... This is why it said that C++ is a “superset” of C. Yet remember, this similarity is in syntax only. C is an imperative programming language, whereas C++ is an object-oriented programming language.
Obsoletely, it is based upon a Student, It take an average person to learn all the fundamentals of the C & C++ language. You will get the Syntax of the language quickly (2–3 months with no experience) assuming you have no experience with programming: You are learning 2–4 hours per day 5 days per week.
Our courseware is designed to give a hands-on approach to the students in C & C++. The course is made up of theoretical classes that teach the basics of each module followed by high-intensity practical sessions reflecting the current challenges and needs of the industry that will demand the students’ time and commitment.
Yes, it is a good language to learn because it doesn't hide anything from you and because so many other languages use a similar syntax. In addition, it has some object-oriented design that can help you get ready to take on other languages. C++ is going to be the most effective on big projects when there is many data to manage. ... Moreover, when you will master C++, it will be super easy for you to jump into Java, C# and pretty much most of similar languages. Many of them inherit many functions from C++ so it is definitely useful to learn it.
Future of C and C++ Not only it is a fundamental language but also its permissive nature allows the user to manage program memory as it offers the feature of dynamic memory allocation, which makes it much faster than any other language. Today, every computer literate person is aware of the term “C/C++ Programming”. It has a good future and is a sound investment and often C++ engineers are good at other languages as well, I generally picked up mobile development faster than the specialist Java programmers (true story).... People who major in C++ and competitive programming tend to pick up new technologies faster.

C++ Operators as member functions:
Aside from the operators which must be members, operators may be overloaded as member or non-member functions. The choice of whether or not to overload as a member is up to the programmer. Operators are generally overloaded as members when they:
- Change the left-hand operand,
- Require direct access to the non-public parts of an object.
- When an operator is defined as a member, the number of explicit parameters is reduced by one, as the calling object is implicitly supplied as an operand. Thus, binary operators take One explicit parameter and unary operators none. In the case of binary operators, the left hand operand is the calling object, and no type coercion will be done upon it. This is in Contrast to non-member operators, where the left hand operand may be coerced.
Number of Operands
Operators are characterized by the number of operands that they require. Most operators require one or two operands but C++ does have one operator that requires three.
Unary Operators
Unary operators only require one operand. Most of the time the operand is placed to the right of the operator but sometimes it is placed to the left.
The most common example is the unary minus: ‑N, which changes the sign of the value stored in variable N.
Binary Operators
Binary operators require two operands. The arithmetic operators are the most familiar examples of binary operators. The assignment operator is also common. "counter" and "5" are the "+" operator's operands, and "A" and the value of the expression "counter + 5" are the "=" operator's operands. Note that the above example ends with a semicolon, which also makes it an example of a statement (specifically, an assignment statement).
Ternary Operator
The single C++ ternary operator is the conditional operator, which is formed with two symbols and requires three operands.
Operator precedence and associativity:
Operator precedence
Now, let consider a more complicated expression, such as 4 + 2 * 3. In order to evaluate this expression, we must understand both what the operators do, and the correct order to apply them. The order in which operators are evaluated in a compound expression is determined by an operators precedence. Using normal mathematical precedence rules (which state that multiplication is resolved before addition), we know that the above expression should evaluate as 4 + (2 * 3) to produce the value 10.
In C++, when the compiler encounters an expression, it must similarly analyze the expression and determine how it should be evaluated. To assist with this, all operators are assigned a level of precedence. Operators with the highest level of precedence are evaluated first.
You can see in the table below that multiplication and division (precedence level 5) have more precedence than addition and subtraction (precedence level 6). Thus, 4 + 2 * 3 evaluates as 4 + (2 * 3) because multiplication has a higher level of precedence than addition.
Operator associativity
What happens if two operators in the same expression have the same precedence level? For example, in the expression 3 * 4 / 2, the multiplication and division operators are both precedence level 5. In this case, the compiler can not rely upon precedence alone to determine how to evaluate the result.
If two operators with the same precedence level are adjacent to each other in an expression, the operators associativity tells the compiler whether to evaluate the operators from left to right or from right to left. The operators in precedence level 5 have an associativity of left to right, so the expression is resolved from left to right: (3 * 4) / 2 = 6.
Table of operators
The below table is primarily meant to be a reference chart that you can refer back to in the future to resolve any precedence or associativity questions you have.
Precedence level 1 is the highest precedence level, and level 17 is the lowest. Operators with a higher precedence level get evaluated first.
- L->R means left to right associativity.
- R->L means right to left associativity.
Parenthesization
In normal arithmetic, you learned that you can use parenthesis to change the order of application of operations. For example, we know that 4 + 2 * 3 evaluates as 4 + (2 * 3), but if you want it to evaluate as (4 + 2) * 3 instead, you can explicitly parenthesize the expression to make it evaluate the way you want. This works in C++ because parenthesis have one of the highest precedence levels, so parenthesis generally evaluate before whatever is inside them.
Now consider an expression like x && y || z. Does this evaluate as (x && y) || z or x && (y || z)? You could look up in the table and see that && takes precedence over ||. But there are so many operators and precedence levels that its hard to remember them all. In order to reduce mistakes and make your code easier to understand without referencing a precedence table, its a good idea to parenthesize any non-trivial compound expression, so its clear what your intent is.
