void main() { int x,b,i;
while ( 1 ) {
scanf("%d",&x); if ( x==0 ) break;
b=1; for ( i=2;i printf("%d",x);
if ( b==0 ) printf("不");
printf("是质数\n");
}
}
怎么用for循环判断输入的数是不是质数
void main() { int x,b,i;
while ( 1 ) {
scanf("%d",&x); if ( x==0 ) break;
b=1; for ( i=2;i printf("%d",x);
if ( b==0 ) printf("不");
printf("是质数\n");
}
}
