Hi, I wanted to know if is there any simple code that can compare two different strings in C++ easily.

How Do I Compare Two Strings in C++?

- Relational operators
- std::compare()
- strcmp() {C library function}
- Write custom code.

Hi, I wanted to know if is there any simple code that can compare two different strings in C++ easily.

Define 'simple code'.

example

str a = 'h'
 
if( 'h' == a ){
 
}else{
 
}

Here, the comparison can be done in three ways.
one - by using strcmp() function
Two - by using compare() function
or else we can directly compare two strings by using comparison operator.

Here I am showing you one of the way by using comparison operators:
let's say we have 2 strings

string a=”abcd”;
string b=”abcd”;

So here we can simply use ‘==’ operator to check if they are equal or not
if(a==b) return true;
else return false;
In order to know more about this you can read this article here.

strcmp might be the one code you could use for

You can use strcmp function to compare two strings.

I've written a code to compare two strings that they are equal or not.

#include <iostream>
using namespace std;

int main ()
{
// declare string variables
string str1;
string str2;

cout << " Enter the String 1: " << endl;
cin >> str1;
cout << " Enter the String 2: " << endl;
cin >> str2;

// use '==' equal to operator to check the equality of the string
if ( str1 == str2)
{
cout << " String is equal." << endl;
}
else
{
cout << " String is not equal." << endl;
}
return 0;
}

You can compare two C++ String using == operator

[Khushi16M]

string s1= "xyz";
string s2= "abc";
if(s1!=s2){
if(s1<s2){
cout<<s2<<" is greater then "<<s1;
}else{
cout<<s1<<" is greater then "<<s2;
}
}else{
court<<"Both the strings are equal.";
}
