c++程序输入dag is ...//判断字符中间有多少个空格，怎么p[i]==' '条件不管用呢？
#include "stdafx.h"
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
char val[30] ={};
cin>>val;
char* p = val;
int count = 0;
for(int i =0 ; p[i]!='\0';i++)

{
count++;
}
}
return 0;
}
int main(int argc ,char *argv[])
{
char val[30] ={};
cin.getline(val,29);//用cin.getline()获取字符串
char* p = val;
int count = 0;
