蓝桥杯基础练习VIP-字符串对比 （C++代码）

解题思路:

注意事项:

参考代码:

#include<iostream>

#include<string>

#include<algorithm>

#include<string>

#include <ctype.h>

using namespace std;

int main(){

string s1, s2;

cin>>s1>>s2;

if(s1.length() != s2.length())

cout<<1<<endl;

else if(s1 ==  s2){

cout<<2<<endl;

}else{

for(int i=0; i<s1.length(); i++){

s1[i] = tolower(s1[i]);

s2[i] = tolower(s2[i]);

}

if(s1 == s2)

cout<<3<<endl;

else

cout<<4<<endl;

}

return 0;

}
