有点看不清你的，按照你的源码编的，运行没问题啊：
#include <stdio.h>
int main(void) {
int x,y,i;
for(i=101;i<200;i++){
for(x=2,y=1;i>x;x++){
if(i%x==0){
y=0;
break;
}
}
if(y==1)
printf("%d is prime\n",i);
else
printf("%d is not prime\n",i);
}
printf("test");
return 0;
}
输出：
101 is prime
102 is not prime
103 is prime
104 is not prime
