I am in a computer programming class at school and need some help on a a part of the program.



Here is my code so far. I am having trouble with the part that says Age = ThisYear - YearBorn;
While trying to output the Age to the screen it keeps coming up with the error C2440 that says cannot convert from int to char *

Any ideas?

you cant subtract two chars! Only numbers (int, float, double)
You have to declare you variables as numbers and then convert the result to char to output it to the screen

your code is kinda unsafe, however, this is what you might be looking for:


you also probably want to "delete" all your pointers, GDK won't do it for you

is saying to the compiler: "Take the pointer address value of 'ThisYear' and subtract from it the pointer address value of 'YearBorn' and put that value into 'Age'"
This is not how pointers are usually done and will not get you what you are looking for.
Create 4 more variables:

These will hold the numeric representations of the character values you entered and held in:

You will need to tell the integer values what they are by adding:

This last bit must be done some time after the input and before the output.

The fastest code is the code never written.
