用C语言写生成10个随机一百以内的加减乘除的算式，之后用户输入十个算式的答案，判断对错，之后刷新再来，如此循环的代码

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main() {
int i, answer, user_answer, count = 0;
char operator;
srand(time(NULL)); // 设置随机数种子

while (1) {
printf("第%d题：", count + 1);
int num1 = rand() % 100 + 1; // 生成1-100之间的随机数
int num2 = rand() % 100 + 1;
int op = rand() % 4; // 生成0-3之间的随机数，分别代表加减乘除

switch (op) {
case 0:
operator = '+';
answer = num1 + num2;
break;
case 1:
operator = '-';
answer = num1 - num2;
break;
case 2:
operator = '*';
answer = num1 * num2;
break;
case 3:
operator = '/';
answer = num1 / num2;
break;
}

printf("%d %c %d = ", num1, operator, num2);
scanf("%d", &user_answer);

if (user_answer == answer) {
printf("回答正确！\n");
} else {
printf("回答错误！正确答案为%d\n", answer);
}

count++;

if (count == 10) {
printf("本轮结束，是否继续？(Y/N)");
char choice;
scanf(" %c", &choice);
if (choice == 'N' || choice == 'n') {
break;
} else {
count = 0;
}
}
}

return 0;
}
