# C++ Exercises: Find the first and last digit of a number

## C++ For Loop: Exercise-56 with Solution

Write a program in C++ to find the first and last digits of a number.

**Visual Presentation:**

**Sample Solution**:

**C++ Code :**

```
#include <iostream> // Include the input/output stream library
using namespace std; // Using standard namespace
int main() // Main function where the execution of the program starts
{
int n, first, last; // Declare integer variables n, first, and last
// Display message asking for input
cout << "\n\n Find the first and last digit of a number:\n";
cout << "-----------------------------------------------\n";
cout << " Input any number: ";
cin >> n; // Read input for the number from the user
first = n; // Assign the input number to the variable 'first'
last = n % 10; // Calculate the last digit of the number
for (first = n; first >= 10; first = first / 10); // Loop to find the first digit of the number
// Display the first and last digit of the number
cout << " The first digit of " << n << " is: " << first << endl;
cout << " The last digit of " << n << " is: " << last << endl;
}
```

Sample Output:

Find the first and last digit of a number: ----------------------------------------------- Input any number: 5679 The first digit of 5679 is: 5 The last digit of 5679 is: 9

**Previous:** Write a program in C++ to display such a pattern for n number of rows using number. Each row will contain odd numbers of number.
The first and last number of each row will be 1 and middle column will be the row number. n numbers of columns will appear in 1st row.

**Next:** Write a program in C++ to find the sum of first and last digit of a number.
