要求输入一个两位数输出器英文单词，下面是我编写的程序，但是程序无法正常运行，求助……
#include<stdio.h>
int main()
{
    int x,m,n;
    printf("请输入一个两位数:");
    scanf("%d",&x);
    m=x/10;
    n=x-10*m;
    printf("您输入的两位数是:");
    if(n=0)
    {
        switch(m)
        {
        case'1':printf("ten\n");break;
        case'2':printf("twenty\n");break;

        case'8':printf("eighty\n");break;
        case'9':printf("ninety\n");break;
        }
    }
    else if(m=1)
    {

程序应该还有好多地方有问题。楼主自己编译找一下吧。

谢谢了，这个确实错了……不过这个改过后还是不能正常运行啊……

你这个错的 很隐蔽 。if(表达式)  括号里面应该是 条件的真假  你弄成赋值语句了。。你可以 写成  n==0  m==1 这个是主要的。

现在手头上没编译器。你自己编译一下。应该能找出错误的。

else if(m>=2)
    {
        {                                  //这里的括号是干嘛的，是想把switch（m）跟switch（n) 隔开吗······貌似本来就是分开的吧····
            switch(m)
            {
            case'2':printf("twenty-\n");break;      //case 后面为什么要把数字用 单引号 括起来啊，这不是字符了吗！ 你声明的m、n可是int啊，不是char要仔细哦(>^ω^<)
            case'3':printf("thirty-\n");break;
            case'4':printf("forty-\n");break;
            case'5':printf("fifty-\n");break;
            case'6':printf("sixty-\n");break;
            case'7':printf("seventy-\n");break;
            case'8':printf("eighty-\n");break;
            case'9':printf("ninety-\n");break;
            }
        }
        {
            switch(n)
            {
            case'1':printf("ten\n");break;
            case'2':printf("twenty\n");break;
            case'3':printf("thirty\n");break;
            case'4':printf("forty\n");break;
            case'5':printf("fifty\n");break;
            case'6':printf("sixty\n");break;
            case'7':printf("seventy\n");break;
            case'8':printf("eighty\n");break;
            case'9':printf("ninety\n");break;
            }
        }
