Basic calculator
PostPosted: Tue Jun 23, 2009 4:59 am     Reply with quote
hi.

I need to add some basic calculations in my code.
Data is entered per keypad and it's displayed on LCD.

It should look something like ultra basic calculator:
1 + 2 = 3 --- display and save data
120,30 * 10% = 120+12,03= 132,03 display and save data.

Your suggestions on solving this ?

Any beginners programming book should have a section on flowcharting or planning how to write a program. Get thee to a library!
