里面包含很多c语言的源码

/* Demonstrates the goto statement */

#include <stdio.h>

int main( void )
{
    int n;

start:

    puts("Enter a number between 0 and 10: ");
    scanf("%d", &n);

    if (n < 0 ||n > 10 )
        goto start;
    else if (n == 0)
        goto location0;
    else if (n == 1)
        goto location1;
    else
        goto location2;

    puts("You entered 0.\n");
    goto end;

location1:
    puts("You entered 1.\n");
    goto end;

location2:
    puts("You entered something between 2 and 10.\n");
