Question

How do you only display the last 5 digits of a number?

Example input:

123456789

Would return: 56789

Answer 1

Let’s assume that required number to convert is an integer. Then you can use a modular mathematic – you can the number convert to the module with base 100 000. That means that only last 5 digits will be kept. The conversion can be done by an operator for remainder of division, the operator is %.

The code is:

int x = 123456;
int lastDigits = x % 100000;
