Algorithm
- Read the first number, let's call it
num1. - Read the second number, let's call it
num2. - Extract the last digit of
num1using the modulo operator%with 10, and store it in a variable, let's call itlastDigit1. - Extract the last digit of
num2using the modulo operator%with 10, and store it in a variable, let's call itlastDigit2. - Compare
lastDigit1withlastDigit2. - If they are equal, print or return "The numbers have the same last digit."
- If they are not equal, print or return "The numbers do not have the same last digit."
Code Examples
#1 Code Example- Check the Last Digit
Code -
Javascript Programming
/* program to check whether the last digit of three
numbers is same */
// take input
const a = prompt('Enter a first integer: ');
const b = prompt('Enter a second integer: ');
const c = prompt('Enter a third integer: ');
// find the last digit
const result1 = a % 10;
const result2 = b % 10;
const 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.`);
}Output
Enter a first integer: 8
Enter a second integer: 38
Enter a third integer: 88
8, 38 and 88 have the same last digit.
Enter a second integer: 38
Enter a third integer: 88
8, 38 and 88 have the same last digit.
