输出10000以内素数有问题

Question

#include <stdio.h>

int main()
{
int x;
int count;
int isprime = 0;

for( x=1; x<=10000; x++){
    for( count=2; count<=x; count++){
        if(x % count==0){
            isprime = 1;
            break;
        }
    }
    if( isprime == 1 ){
        printf("%d\n",x);
        }
    }

return 0;

}

Answer 1

放循环里边

#include <stdio.h>

int main()
{

int count;

for(int x=2; x<=1000; x++){
    int isprime = 1;
    for( count=2; count<x; count++){
        if(x % count==0){
            isprime = 0;
            break;
        }
    }
    if( isprime == 1 ){
        printf("%d\n",x);
        }
    }
 
return 0;
}
