    a--;
}
while( a > 0 );

for语句代码段

int i;
 
for( i=1; i <= 100;i++)
{
    sum += i;
}

goto语句

int i, j;

for ( i = 0; i < 10; i++ )
{
    printf( "Outer loop executing. i = %d\n", i );
    for ( j = 0; j < 2; j++ )
    {
        printf( " Inner loop executing. j = %d\n", j );
        if ( i == 3 )
            goto stop;
