Syllabus of Programming in C (C11) – Advanced Features Certification Online Training

• C is a language for small, fast programs
• how do you run the program?
• Two types of command

• Using memory pointers
• How do you pass a string to a function?
• Array variables are like pointers…
• Why pointers have types
• Using pointers for data entry
• scanf()
• fgets() is an alternative to scanf()

• Create an array of arrays
• Find strings containing the search text
• Using the strstr() function
• Array of arrays vs. array of pointers

• Introducing the Standard Error
• fprintf() prints to a data stream
• Connect your input and output with a pipe
• The bermuda tool
• Creating your own data streams
• There’s more to main()

• Data types
• Type Casting
• Creating your first header file
• The shared code needs its own header file
• Automate your builds with the make tool

• Create your own structured data types with a struct
• You need a pointer to the struct
• (*t).age vs. *t.age
• A union lets you reuse memory space
• An enum variable stores a symbol
• Bitfields store a custom number of bits

• Linked lists are like chains of data
• Linked lists allow inserts
• Create a recursive structure
• Create islands in C
• Inserting values into the list
• Use the heap for dynamic storage
• Give the memory back when you’re done
• Ask for memory with malloc()…
• Let’s fix the code using the strdup() function

• Pass code to a function
• Every function name is a pointer to the function…
• Every function name is a pointer to the function…
• Get it sorted with the C Standard Library
• Use function pointers to set the order
• Create an array of function pointers

• Angle brackets are for standard headers
• Sharing .h header files
• Share .o object files by using the full pathname
• An archive contains .o files
• Create an archive with the ar command…
• Dynamic linking happens at runtime
• create an object file

• The exec() functions
• The array functions: execv(), execvp(), execve()
• unning a child process with fork() + exec()

• Redirecting input and output
• A look inside a typical process
• Redirection just replaces data streams
• fileno() tells you the descriptor
• Connect your processes with pipes
• Case study: opening stories in a browser
• Opening a web page in a browser
• The death of a process
• Catching signals and running your own code
• Rewriting the code to use a signal handler
• Use kill to send signals

• The Internet knock-knock server
• Knock-knock server overview
• BLAB: how servers talk to the Internet
• Reading from the client
• The server can only talk to one person at a time
• You can fork() a process for each client
• Writing a web client
• Clients are in charge
• Create a socket for an IP address
• getaddrinfo() gets addresses for domains

• Create threads with pthread_create
• Use a mutex as a traffic signal
