Making a calculator in proteus and ccs

[enyam.agbodjavou]

hi people,
I am making a simple calculator. I am not using the keypad but the buttons.
The code below is how I take input from the buttons,
num1 is an array of 4.

if(input(PIN_C1)==1)
{
if(press==0)
{
printf(lcd_putc,"\f");
}
printf(lcd_putc,"8");
Delay_ms(500);
press=press+1;
num1[press=press+1]=8;
}

I did the same for all the other numbers. but when I enter 45+2 for example, it only takes the first digit and add it to the 2 so it will do 4 + 2 and the answer will be 6 instead of 46!
Please help

as you're a first time poster.....
some comments..
1) Please read top sticky called PIC101.
2) Proteus is busted, can't be fixed, no one here can be bothered with it.
3) Post a COMPLETE program, using the 'code[]' button. We must know PIC type, compiler version, etc. to properly help you
4) Confirm you are using real hardware. There is a HUGE difference to what Proteus allows versus the Real World.
