C serial 5-functions and return

Time:2020-9-18

1、 Return statement

1. The main function has a return statement, but it can not. For the main function, after running the last line of statement, it will automatically return a 0, but other functions are not allowed. In order to form a good habit, please add return 0 at the end of the main function;

2. The return statement is a jump statement.

3. Examples

#include 

void builder(void);

int main(void){

    printf("I will summon the buttler function.\n");

    buttler();

    printf("haoba");

   

    return 0;

}

void buffer(void){

    printf("buffer function");

}

 

The first time builder functions appear, we call them function prototypes. Function prototypes are a form of declaration that tells the compiler that a function is being used. Therefore, function prototypes are also called function declarations.
