c++ string comparison

// C++ program to check if
// two strings are identical
#include <bits/stdc++.h>
using namespace std;
  
int main()
{
  
    char string1[100], string2[100];

    // is to be checked

    // Get the strings which
    // is to be checked
    cin >> string2;

Enter the second string: " << string2;
  
    // Check if both strings are equal
    cout << "
Are both strings same: ";

string comparison c++

#include <iostream>
using namespace std;
 
int main() {
    string str1 = "mango";

C++ String Compare Example

#include <iostream>  
#include <cstring>  
using namespace std;  
int main ()  
{  
  char key[] = "Softhunt.net";  
  char buffer[50];  
  do {  
     cout<<"Which is your favourite tutorial website? ";  
     cin>>buffer;  
  } while (strcmp (key,buffer) != 0);  
 cout<<"Answer is correct!!"<<endl;  
  return 0;  
}

compare function in c++

// CPP code for demonstrating
// string::compare (const string& str) const
 
#include<iostream>
using namespace std;
 
void compareOperation(string s1, string s2)
{
    // returns a value < 0 (s1 is smaller than s2)
    if((s1.compare(s2)) < 0)
        cout << s1 << " is smaller than " << s2 << endl;
 
    // returns 0(s1, is being compared to itself)
    if((s1.compare(s1)) == 0)
        cout << s1 << " is equal to " << s1 << endl;
    else
        cout << "Strings didn't match ";
     
}
 
// Driver Code
int main()
{
    string s1("Geeks");
    string s2("forGeeks");
    compareOperation(s1, s2);
     
    return 0;
}
