c语言中的判断素数程序填空

Question

这段代码里有两个空，希望能帮忙解答一下

 #include <stdio.h>
#include "math.h"

void main() {
    int m, k, i, n = 0;
    for (m = 11; m <= 99; m++) {
        k = ___1___ sqrt(m);
        for (int i = 2; i <= k; i++) {
            if (m % i == 0) {
                break;
            }
            if (__2__) {
                printf("%5d", m);
                n = n + 1;
            }
            if (n % 10 == 0) {
                printf("\n");
            }
        }
        printf("\n");
    }
}

供参考：

#include <stdio.h>
#include "math.h"
void main() {
    int m, k, i, n = 0;
    for (m = 11; m <= 99; m++) {
        k = (int)sqrt(m);    //___1___ 
        for (i = 2; i <= k; i++) {
            if (m % i == 0) {
                break;
            }
            if (i >= k) {    //(__2__)
                printf("%5d", m);
                n = n + 1;
                                 //}
            if (n % 10 == 0)     //{
                printf("\n");
            }
        }
        //printf("\n");
    }
