Question

C++

Write a program that checks whether the first digit of the entered number equals the last digit.

Answer 1

Answer:

Explanation:

last_digit variable stores the last digit using mod operator and then using while loop, removing the last digit one by one till n is greater than 0, the first_digit variable is assigned the first digit.

Then, both digits are matched and output is printed.

Code:

#include <iostream>

using namespace std;

int main()
{
int n;
cout<<"Enter the number: ";
cin>>n;
  
int last_digit = n%10;
int first_digit = n%10;
n = n/10;
  
while(n>0)
{
first_digit = n%10;
n = n/10;
}
if(first_digit==last_digit)
{
cout<<"First digit is equal to the Last digit"<<endl;
}
else
{
cout<<"First digit is not equal to the last digit"<<endl;
}

return 0;
}
