Question

I am supposed to make an if statement program that changes the last digit to 1 if it ends in 0 .

input is a whole number.

Example:

12340 changed to 12341
1230320 changed to 1230321

Answer 1

You should check for last digit and if it is zero then add 1 to number.

if(number%10 == 0)
{ 
   return number +1;
}
return number
