/* program to check whether the last digit of three
numbers is same */

// take input
let a = prompt('Enter a first integer: ');
let b = prompt('Enter a second integer: ');
let c = prompt('Enter a third integer: ');

// find the last digit
let result1 = a % 10;
let result2 = b % 10;
let result3 = c % 10;

// compare the last digits
if(result1 == result2 && result1 == result3) {
    console.log(`${a}, ${b} and ${c} have the same last digit.`);
}
else {
    console.log(`${a}, ${b} and ${c} have different last digit.`);
}

Enter a first integer: 8
Enter a second integer: 38
Enter a third integer: 88
8, 38 and 88 have the same last digit.
