嵌入式C语言goto语句

goto语句用于在一个函数里面实现代码的跳转

#include <stdio.h>

int main (int argc, char *argv[]){


    printf ("1\n");
    goto NEXT;

    printf ("2\n");

    printf ("3\n");

NEXT:
    printf ("4\n");
    return 0;
}

使用goto实现循环

int i = 1;
int sum = 0;

JOOP:

sum += i;
i++;

if (i <= 100){
goto JOOP;
}

//end
