I Wrote My First Cool C++ Program Today

[naodx]

mkwan,

I'm not sure what you are talking about there, please give more info. Are you talking about the division function????

[naodx]

trip,

my first program was some variant of hello, but it was using the old apple II basic back in junior high, if that tells you anything.

I did do the currency conversion program, but it wasn't until I hit college and it was in c++ (ok so I had a few years between high school and college, but at least I finally made it)

[mkwan]

there is no check if a user inputs letters instead of numbers

[naodx]

mkwan,

very true, but you usually don't do to much for error checking in a beginning level program. That comes later after you master the basics.

I would say, whenever you want to show off code like this, use the [ code ] [ /code ] tag in vB... put your code between these tags (without the spaces), and it will format correctly.

Like this: (btw, thanks for the code. You really know your stuff)

#include <iostream>
 
 using namespace std;
 
 void add( float, float );
 void sub( float, float );
 void mult( float, float );
 void divd( float, float );
 
 int main()
 {
     cout << "Input two numbers and an operator ";
     float a;
     float b;
     char oper;
     cin >> a >> b >> oper;
 
     switch( oper )
     {
         case '+':
             add( a, b );
             break;
         case '-':
             sub( a, b );
             break;
         case '*':
             mult( a, b );
             break;
         case '/':
             divd( a, b );
             break;
         default:
             break;
     }
 
     return( 0 );
 }
 
 void add( float x, float y )
 {
     cout << "Answer: " << x + y << endl;
 }
 
 void sub( float x, float y )
 {
     cout << "Answer: " << x - y << endl;
 }
 
 void mult( float x, float y )
 {
     cout << "Answer: " << x * y << endl;
 }
 
 void divd( float x, float y )
 {
     if( y == 0 )
     {
         cout << "Can't divide by zero, setting denominator to 1" << endl;
         y = 0;
     }
     cout << "Answer: " << x / y << endl;
 }

Is there a way I can edit the code si I can type in 5+5 insted of 5 5+

[naodx]

just change your cin statement:

cin >> a >> oper >> b;

that will do it
