Functions are essential building blocks in C from "summary" of C Programming Language by Brian W. Kernighan,Dennis Ritchie
Functions are at the heart of C programming. They are crucial building blocks that allow us to break down our code into smaller, more manageable pieces. By encapsulating specific tasks within functions, we can organize our code in a logical and modular way. This not only makes our code easier to read and understand but also makes it more maintainable and reusable. In C, a function is defined with a return type, a name, a parameter list, and a body. The return type specifies the data type of the value that the function will return, if any. The name is used to identify the function and call it from other parts of the program. The parameter list contains variables that hold the values passed to the function when it is called. The body of the function contains the actual code that performs the desired task. Functions can be called from other functions or from the main program. When a function is called, control is transferred to the function, the code in the function body is executed, and then control is returned to the calling functi...
