Answer:

Simply you have to follow this.....⬇️⬇️

#include <iostream>

using namespace std;

int main()

{

int n,first,last,sum;

cout << "\n\n Find the sum of first and last digit of a number:\n";

cout << "------------------------------------------------------\n";

cout << " Input any number: ";

cin >> n;

first = n;

last=n % 10;

for(first=n;first>=10;first=first/10);

cout<<" The first digit of "<<n<<" is: "<<first<<endl;

cout<<" The last digit of "<<n<<" is: "<<last<<endl;

cout<<" The sum of first and last digit of "<<n<<" is: "<<first+last<<endl;

}
