1. character string

【 Solution code 】

solution 1： Use character array

#include <bits/stdc++.h>
using namespace std;
int main()
{
    
    char s[35], a, b;// character a Replace with b
    cin >> s >> a >> b;
    int len = strlen(s);
    for(int i = 0; i < len; i++)
    {
    
        if(s[i] == a)
            s[i] = b;
    }
    cout << s;
    return 0;
}

solution 2： Use string class

#include <bits/stdc++.h>
using namespace std;
int main()
{
    
    string s;
    char a, b;// character a Replace with b
    cin >> s >> a >> b;
    for(int i = 0; i < s.length(); i++)
    {
    
        if(s[i] == a)
            s[i] = b;
    }
    cout << s;
    return 0;
