goto语句在编程中用的很少,几乎不怎么用,主要就是在程序中设计一个标记,然后通过goto跳转到标记位置,百度上抄了一个程序:
#include <stdio.h>
int main()
{
int i, j;
for ( i = 0; i < 10; i++ )
{
printf( "Outer loop executing. i = %d\n", i );
for ( j = 0; j < 3; j++ )
{
printf( " Inner loop executing. j = %d\n", j );
if ( i == 5 )
goto stop;
}
}
/* This message does not print: */
printf( "Loop exited. i = %d\n", i );
stop: printf( "Jumped to stop. i = %d\n", i );//stop: 就是标签
return 0;
