输出当前文件执行代码,__FILE__ 为当前执行的文件常量。
实例
#include <stdio.h>
int main() {
FILE *fp;
char c;
fp = fopen(__FILE__,"r");
do {
c = getc(fp);
putchar(c);
}
while(c != EOF);
fclose(fp);
return 0;
}
输出结果为:
#include <stdio.h> int main() { FILE *fp; char c; fp = fopen(__FILE__,"r"); do { c = getc(fp); putchar(c); } while(c != EOF); fclose(fp); return 0; }
