用C语言程序从键盘输入high，计算并输出high以内最大的10个素数之和

#include <stdio.h>

int is_prime(int num) {
    if (num <= 1) {
        return 0;
    }
    for (int i = 2; i * i <= num; i++) {
        if (num % i == 0) {
            return 0;
        }
    }
    return 1;
}

int main() {
    int high, count = 0, sum = 0, i = 2;
    printf("请输入high的值：");
    scanf("%d", &high);
    while (count < 10 && i <= high) {
        if (is_prime(i)) {
            sum += i;
            count++;
        }
        i++;
    }
    printf("high以内最大的10个素数之和为：%d\n", sum);
    return 0;
}
