How do you set rules for the last two digits of a number?

Answer 1

I assume you are using C.

I also assume that you stored the input in an int.

All you need to do is store that int into an array.

You can do this using itoa.

Just search about it.

When you have done this, use the index of the last two digits of the array to check their values.

If the number of digits is not definite, create a loop like this to count the number of digits:

array digits[MAX];

int c = 0;

while(array[c]!=null)

{

c++;

}

// c will then be the number of digits.

example:

inputted digit: 12345

// the value of c is now 4

//Take note that the index of arrays is 0

//index: [0][1][2][3][4]

//values: [1][2][3][4][5]

To access the last two digits:

digits[4] // this is 5

digit[3] // this is 4
