In this video we will learn how to reverse some integer number, before this video we learned how to reverse and array of string.
We will use module operator for extracting single numbers from the given number then keep dividing that number and then and keep adding the extracted number to a new number and like this in the end we will have the reversed number.

REVERSE NUMBER WITHOUT SWAP FUNCTION

#include<bits/stdc++.h>
using namespace std;
int rev(int digit)
{
int reverse_number=0;
int remainder=0;
while(digit!=0)
{
remainder=digit%10;
+ remainder;
digit=digit/10;
}
cout<<reverse_number;
}
int main()
{
int digit;
cin>>digit;
rev(digit);
}

You can also use atoi() then reverse the string and vice versa.

bro thats so big brain holy shit <3 <3 <3

#include<bits/stdc++.h>
using namespace std;
int rev(int arr[], int n)
{
int i=0;
int j=n-1;
while(i<j)
{
swap(arr[i], arr[j]);
j--;
i++;
}
for(int i=0;i<n;i++)
{
cout<<arr[i];
}

}
int main()
{
int n;
cin>>n;
int arr[n];
for(int i=0;i<n;i++)
{
cin>>arr[i];
}
rev(arr, n);
}
