题目描述

将其全部换成小写即可达到忽略大小写比较字符串的效果。

样例

#include<iostream>
#include<cstring>
using namespace std;
int main()
{
    string a,b;
    getline(cin,a);
    getline(cin,b);
    int i;
    for (int i = 0; i < a.size(); i ++)
    {
        if (a[i] >= 'A' && a[i] <= 'Z') 
        a[i] += 32;
    }
    for (int i = 0; i < b.size(); i ++)
    {
        if (b[i] >= 'A' && b[i] <= 'Z')
        b[i] += 32;
    }
    if(a<b) cout<<"<";
    else if(a>b) cout<<">";
    else cout<<"=";
    return 0;
}
