Problem putting variables cumulatively into a string,

warny_maelstrom · #1 05-Feb-2004, 05:07

Im tryin to create a calculator where u can put the number in by typing or by press buttons. I have a problem when i try get the input of the buttons into the string. The code is very long and poor coz im not sure how to shorten it until i get everything sorted, so iv eft the chucks out of code that are just repeats of the above lines. How do i get a string to accept each term cumulatively so i can have a multi-digit number?

CPP / C++ / C Code:

#pragma windows 300000,500000,"cwp_ico.rc" 
#include <windows.h> 
#include <stdio.h> 

int number1=0,number2=0; 
double ans;
int One1(),Two1(),Three1(),Four1(),Five1(),Six1(),Seven1(),Eight1(),Nine1(),Zero1(); 
int One2(),Two2(),Three2(),Four2(),Five2(),Six2(),Seven2(),Eight2(),Nine2(),Zero2(); 
int Add(),Subtract(),Multiply(),Divide(),Close(); 
int main()

        { 
        winio("%bg%ca[Windows Calculator]&",RGB(255,100,100)); 
        winio("%fn[Paris]%ts First Number: %rd&",2.5,&number1); 
        winio("\tSecond Number: %rd\n&",&number2);
        winio("\t%ts%bc[grey]%`^bt[1]&",1.5,One1);
        winio("%bc[grey]%^bt[2]&",Two1);
        winio("%bc[grey]%^bt[3]&",Three1);
        winio("%bc[grey]%^bt[4]&",Four1);
        winio("%bc[grey]%^bt[5]&",Five1);
        winio("\t\t\t%bc[grey]%^bt[1]&",One2);
        winio("%bc[grey]%^bt[2]&",Two2);
        winio("%bc[grey]%^bt[3]&",Three2);
        winio("%bc[grey]%^bt[4]&",Four2);
        winio("%bc[grey]%^bt[5]&",Five2);
//repeated for all numbers but on a separate line//
        winio("\n%ts %bc[red]%^bt[+]\t&",2.0,Add);  
        winio("%bc[red]%^bt[-]\t&",Subtract); 
        winio("%bc[red]%^bt[*]\t&",Multiply); 
        winio("%bc[red]%^bt[/]\t&",Divide); 
        winio("%bf%ts  answer  %8rf&",3.0,&ans);
        winio("\n\t\t%ts  %bc[black]%^bt[%tc\t,Closeeeeeeeeeeeeeee]",2.0,Close); 
        }
       
        
int One1()
        {
        number1=1;
        return 1;
        }
int Two1()
        {
        number1=2;
        return 1;
        }
//repeated over until Zero1//
int One2()
        {
        number2=1;
        return 1;
        }
int Two2()
        {
        number2=2;
        return 1;
        }
//repeated over until Zero2//       
//start of processing//
int Add() 
        { 
        ans=number1+number2; 
        return 1; 
        } 
int Subtract() 
        { 
        ans=number1-number2; 
        return 1; 
        } 
int Multiply() 
        { 
        ans=number1*number2; 
        return 1; 
        } 
int Divide() 
        { 
        ans=number1/number2; 
        return 1; 
        }
int Close()
        {
        return 0; 
        }

Hi Warny. I hate to answer a question with a question, but I am having a little trouble following what you are doing.

If you have a complete string that is a number, you can convert that entire string to a double (or long or int) by using on of the following

CPP / C++ / C Code:

int atoi(const char* string);
long atol(const char* string);
double atof(const char* string);

These are all defined in the stdlib.h header file. I am not sure if this helps or not as I had a little trouble figuring out your question.

Incidently, I am writing a library that will parse an entire string that I hope to post this weekend sometime. It is based upon the discussion in this thread. I am not sure if this is something that you would be interested in or not.

Anyway, good luck!

dsmith, im tryin to get so that when someone presses more than one button that iv created that i get a string of numbers as an input rather than just changing the original number. eg. user presses button[1], number 1 appears in the "First Number" box, then when they press button[4] only number 4 appears where as i would like 14 to appear and b the input once the user clicks the appropriate button.
At the moment it works fine if only suming 2 single digit numbers together but i really want to b able to use bigger numbers.

tay:-Iv only been doin programmin for a month or two so im not completely sure but its windows input output, i think it lets u open a windows box instead of the normal crap black dos-prompt type box that normally comes up when u run a program. Check if u have the windows.h program within ur libary coz that might b the problem, if u do take out the "#pragma windows 300000,500000,"cwp_ico.rc"" bit coz im not sure where this comes from i only know wot it does and its just aesthetics.
