使用c语言并使用随机函数生成100个英文半角字符并输出，统计其中大写字母、小写字母、数字及其他字符的个数。

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

int main()
{
    int i, count_upper = 0, count_lower = 0, count_digit = 0, count_other = 0;
    char ch;
    srand(time(NULL)); // 初始化随机数种子
    for (i = 0; i < 100; i++)
    {
        ch = rand() % 94 + 33; // 生成33~126之间的随机数
        printf("%c", ch);
        if (ch >= 'A' && ch <= 'Z')
            count_upper++;
        else if (ch >= 'a' && ch <= 'z')
            count_lower++;
        else if (ch >= '0' && ch <= '9')
            count_digit++;
        else
            count_other++;
    }
    printf("\n大写字母个数：%d\n", count_upper);
    printf("小写字母个数：%d\n", count_lower);
    printf("数字个数：%d\n", count_digit);
    printf("其他字符个数：%d\n", count_other);
    return 0;
}
