File compositor

---

One 、 demonstration

1. Input file name

2. Check out the newly generated NewPng file

2.1 NewPng.png

2.2 NewPng.rar

Example ：

Two 、 Source code

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>


int Sub_3()
{
    
	char ch, pic_name[20], file_name[20], finish_name[20];
	FILE* f_pic, * f_file, * f_finish;
	printf(" Please enter the name of the picture you want to compose \n");
	printf(" picture ：");
	scanf("%s", pic_name);
	printf(" file ：");
	scanf("%s", file_name);
	printf(" Born into ：");
	scanf("%s", finish_name);
	if (!(f_pic = fopen(pic_name, "rb")))
	{
    
		printf("Cannot open the picture %s !", pic_name);
		return 0;
	}
	if (!(f_file = fopen(file_name, "rb")))
	{
    
		printf("Cannot open the file %s !", file_name);
		return 0;
	}
	if (!(f_finish = fopen(finish_name, "wb")))
	{
    
		printf("Cannot open the file %s !", finish_name);
		return 0;
	}
	while (!(feof(f_pic)))// Returns a non at the end of the file 0 value  
	{
    
		ch = fgetc(f_pic);
		fputc(ch, f_finish);
	}
	fclose(f_pic);
	while (!(feof(f_file)))
	{
    
		ch = fgetc(f_file);
		fputc(ch, f_finish);
	}
	fclose(f_file);
	fclose(f_finish);

}
int main()
{
    
	Sub_3();

	system("pause");
    return 0;
}

Be careful ： file name ( route ) It's using scanf Function get from console , So there can be no spaces , Otherwise, it will be truncated .
