写Ｃ++程序，请用标准Ｃ++写
比如：
头文件是 <iostream>（配合namespace)，而不是<iostream.h>（估计你们看的书是国人的吧，老掉牙了）
main函数返回类型是int
用string代替char[]，用cin代替getchar()
等等，找一本好的书学习比较重要，另外建议多用库函数
再把你的代码改写一下：
#include<iostream>
#include <string>
#include <cctype>
using namespace std;
int main()
{
string str;
getline(cin, str);
cout<<"Inputted: \n"<<str<<endl;
size_t countChars = 0;
size_t countDigits = 0;
size_t countOthers = 0;
for (size_t i = 0; i < str.size(); ++i) {
if (isalpha(str[i]))
++countChars;
else if (isdigit(str[i]))
++countDigits;
else
++countOthers;
}
cout<<"Chars: "<<countChars<<", Digits: "<<countDigits
<<", Others: "<<countOthers<<endl;
return 0;
}
增加一个提示输入的语句。呵呵。完美一点还是好的不是么？
#include<iostream>
#include <string>
#include <cctype>
using namespace std;
int main()
{
string str;
cout<<"Input a word segment press to return to car be over"<<endl; //提示输入
getline(cin, str);
cout<<"Inputted: \n"<<str<<endl;
size_t countChars = 0;
size_t countDigits = 0;
size_t countOthers = 0;
for (size_t i = 0; i < str.size(); ++i) {
if (isalpha(str[i]))
++countChars;
else if (isdigit(str[i]))
++countDigits;
else
++countOthers;
}
cout<<"Chars: "<<countChars<<", Digits: "<<countDigits
<<", Others: "<<countOthers<<endl;
return 0;
}
