[编程入门]自定义函数之字符类型统计

解题思路:

注意事项:

参考代码:

#include<bits/stdc++.h>

using namespace std;

void count(string s)

{

    int a=s.size();

    int cnt1=0,cnt2=0,cnt3=0,cnt4=0;

    for(int i=0;i<a;i++)

    {

        if(s[i]>='0' && s[i]<='9') cnt1++;

        else if(s[i]>='a' && s[i]<='z' || s[i]>='A' && s[i]<='Z') cnt2++;

        else if(s[i]==' ') cnt3++;

        else cnt4++;

    }

    cout<<cnt2<<" "<<cnt1<<" "<<cnt3<<" "<<cnt4<<endl;

}

int main()

{

    string s;

    getline(cin,s);

    count(s);

    return 0;

}
