C Function Definitions. A function definition specifies the name of the function, the types and number of parameters it expects to receive, and its return type. A function definition also includes a function body with the declarations of its local variables, and the statements that determine what the function does.
There is no call by reference in C. You can pass the argument only through call by value. In call by value, you are sending the value of the argument, and within the function, a local variable is created to hold that value. So any changes that is made to this local variable wont be reflected in the calling function.
