# Check If Two Strings Are Anagram using C++

Solving a real-world problem in a digital way only requires the ability to be able to code. Well for some programming is tough while for some it’s the most interesting thing to do. However, things get a bit complicated when problems get difficult. Therefore practising tricky questions gives our brain a quick start to make it faster. Especially when you do programming using C++. And for a fact, C++ is considered one of the hardest programming languages to learn. But that doesn’t mean you can’t master it. In this article we will try to solve a simple C++ program, that is we are going to check if two strings are anagram or not.

Practising these types of questions also helps to get an upper edge in Competitive Programming. So open up your IDE and let’s get started real quick. Once you understand the logic practice this program on your own to make your brain work in a problem-solving way. This is a somewhat easy question so you might not get asked in an interview. But make sure to practice it on your own after reading this article.

## What is An Anagram String?

• An anagram of a string is a string that consists same no of characters representing the same letters as that of the string we’re comparing with. Though anagram strings have the same character count the order in which characters are written should be different in both the strings.

• For example, “abcd” and “dcba” are an anagram of each other.

## What’s The Approach?

• However, before that, we will check the length of both the strings if the length is not similar then it is clear that strings are not anagrams.

• However, if the length of strings is equal then we will sort both of them in ascending order using the `sort()` function. After that, we will check if both the sorted strings are equal to each other or not. If yes then strings are anagrams and vice versa.

## C++ Program To Check If Two Strings Are Anagram

Input:

`str1 ``=` `"LISTEN"`
`str2 ``=` `"SILENT"`
Output:
`The two strings are anagram of each other`
```// C++ program to check whether two strings are anagrams of each other

#include <bits/stdc++.h>
using namespace std;

/* function to check whether two strings are anagram of
each other */
bool areAnagram(string str1, string str2)
{
// Get lengths of both strings
int n1 = str1.length();
int n2 = str2.length();

// If length of both strings is not same, then they
// cannot be anagram
if (n1 != n2)
return false;

// Sort both the strings
sort(str1.begin(), str1.end());
sort(str2.begin(), str2.end());

// Compare sorted strings
for (int i = 0; i < n1; i++)
if (str1[i] != str2[i])
return false;

return true;
}

// Driver code
int main()
{
string str1 = "LISTEN";
string str2 = "SILENT";

// Function Call
if (areAnagram(str1, str2))
cout << "The two strings are anagram of each other";
else
cout << "The two strings are not anagram of each "
"other";

return 0;
}
```
