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;
