C programming

In C programming, a function call is a statement that invokes or executes a function

Examples :


                        #include <stdio.h>

                            // Function declaration
                            void myFunction(); 
                            
                            int main() {
                                printf("Inside main function.\n");
                            
                                // Function call
                                myFunction();
                            
                                printf("Back inside main function.\n");
                            
                                return 0;
                            }
                            
                            // Function definition
                            void myFunction() {
                                printf("Inside myFunction.\n");
                            }

Output:

      Inside main function.
      Inside myFunction.
      Back inside main function

Q1. In C programming, what is the purpose of a function prototype?

A. It defines the structure of the function

B. It declares the function's existence to the compiler

C. It contains the main logic of the function

D. It is used for printing output

Q2. If a function is defined after the main function in a C program, how can you call it from main without a function prototype?

A. It is not possible; a prototype is mandatory

B. Call the function normally; the compiler will handle it

C. Declare the function inside main before calling it

D. Use the extern keyword before calling the function
