Format - C language project sub file

1. The header file （head.h）:

// Declaration for storing functions 
// The main function is to be quoted by other documents ：#include"head.h"

#define _CRT_SECURE_NO_WARNINGS  // If not defined here , If quoting this (head.h) Of cpp This definition should be used in the document , Then it needs define
#include<stdio.h>                // If the header file is not referenced here , Then quote this (head.h) Of cpp Write your own reference in the document 

void temp1();
void temp2();

2. Implementation of functions in header file （head.cpp）：

// The main function is to realize the header file （head.h） The function in 

#include"head.h"   // Reference the header file （head.h） All definitions in , Include define, Referenced header file, etc .

void temp1() {
	int x;
	scanf("%d", &x);
	printf("temp1\n");
	temp2();
}

void temp2() {
	printf("temp2\n");
}

3. The main program （c1.cpp）：

//#define _CRT_SECURE_NO_WARNINGS   // When the referenced header file （head.h） When this definition is included in , It can be deleted here 
//#include<stdio.h>                 // When the referenced header file （head.h） When this header file is included in , It can be deleted here 
#include"head.h"                    // quote head.h, Want to refer directly to all the contents of its definition , Indirect reference head.cpp

int main() {
	temp1();
	return 0;
}
