有这么一个题
它是要求:输入一行字符,分别统计其中英文字母,空格,数字和其他字符的个数(它是要求用while,do while嵌套来做),请大家帮帮忙,谢谢.
下面这个是我编的,没做完,因为做一半就发现不对,就没往下编了,请大家多多鞭苔.





#include<stdio.h>
void main()
{
int x;
char i,ans;
ans='y';
do{
x=0;
printf("请输入一行字符: ");
fflush(stdin); //清空键盘输入缓冲区//
do
{
i=getchar();
x++;
}while (i!='\n');
printf("\n 字符的个数为: %d",--x);
if ((i>='a'||i<='z')||(i>='A'||i<='Z'))
{
printf("\n 字母的个数为: %d",x);
}
printf("\n 是否需要输入更多的字符(Y/N)? ");
ans=getchar();
}while (ans=='Y'||ans=='y');
}

郁闷中,弄了半天,还是不对啊~
希望懂的朋友们,帮忙看看~指点指点

你这个等距离运行起来有错啊?
