思维导图

提示并输入一个字符串，统计该字符中大写、小写字母个数、数字个数、空格个数以及其他字符个数
要求使用C++风格字符串完成
 

#include <iostream>
#include<array>

using namespace std;

int main()
{
    int a=0,A=0,num=0,space=0,other=0;

    array<char,20> str;
    array<char,20>::iterator iter;

    cout << "请输入一个字符串：" << endl;
    for(iter = str.begin();iter != str.end();iter++)
    {
        cin >> *iter;
    }

    for(iter = str.begin();iter != str.end();iter++)
    {

        if(int(*iter)>=97&&int(*iter)<=122)
        {
            a++;
        }
        else if(int(*iter)>=65&&int(*iter)<=90)
        {
            A++;
        }
        else if(int(*iter)>=48&&int(*iter)<=57)
        {
            num++;
        }
        else if(int(*iter)==32)
        {
            space++;
        }
        else
        {
            other++;
        }
    }

    cout << "小写：" << a << endl;
    cout << "大写：" << A << endl;
    cout << "数字：" << num << endl;
    cout << "空格：" << space << endl;
    cout << "其他：" << other << endl;

    return 0;
}
