View Full Version : trying out c++

02 February 2005, 02:52 PM
I have run into some problems while trying to write a Pounds to kilos conversion program in c++. no matter what number i press, the program always goes to the kilos to pounds part...
here's the code.

#include <iostream.h>
void PoundsToKilos() {
cout << "Enter the value in Pounds\n";
float x;
cin >> x;
cout << "The value in kilos is=\n "<< x/2.2;
void KilosToPounds() {
cout <<"enter the value in Kilos\n";
float x;
cout <<"the value in Pounds is= "<<x*2.2;
int main() {
int choice;
cout <<"Weight conversion Program\n";
cout <<"=========================\n";
cout <<"please choose\n";
cout <<"1.) Kilos to pounds\n";
cout <<"2.) Pounds to Kilos\n";

if (choice=1)
KilosToPounds ();
else if (choice=2)
PoundsToKilos ();

not too sure about this, since i work mainly in java/c, but perhaps you need to atoi() the input before the conditional statement?

Hah Hah:)

change the if (choice=1)


if (choice == 1)

In C++ comparision is "==" and "=" is assignment. In your code you are doing Assignment first and the comparing choice.

The code if(choice=1) is the same as saying

choice = 1;

since now choice is greater than Zero and hence "not false" it will go into the first "if" condition.

Hi Mr. Loco, try

if (choice == 1)

man, mr. loco. the obvious mistakes can really screw u over can't they? i dont know how many times ive not realized something because i forgot a semi colon or forgot to close a bracket somewhere.

true...the worst thing about that is that you are looking for something completely different and you spend hours looking for it.
