C语言 fputs 写一个字符串到文件中去

Posted 2021-05-14 Aiden (winner)

函数原型：
#include <stdio.h>
int fputs( const char *str, FILE *stream );

#include <stdio.h>

int main(void) {
	FILE *file1;
	FILE *file2;
	char tmp[64];
	
	char c;
	
	file1 = fopen("test.c", "r");
	file2 = fopen("test2.c", "w");
	
	while (fgets(tmp, sizeof(tmp), file1) != NULL) { 
		fputs(tmp, file2);
	}
	
	fclose(file1);
	fclose(file2);
	return 0;
}
