Here is another that I did, but there is a little bug which won�t take you more than less minute to fix it:

When user selects 0 I want to exit�.

Where is my mistake?

(Toggle Plain Text)

#include <iostream>
#include <stdlib.h>

using namespace std;

int main()
{
 
 int option,number;
 double result;
 // menu option
 cout << "Program to convert from Inches, feet and yards to meters" <<endl;
 cout << "--------------------------------------------------------" <<endl; 
 cout << "Enter 1 to convert from Inches to meters" <<endl;
 cout << "----------------------------------------" <<endl;
 cout << "Enter 2 to convert from feet to meters" <<endl;
 cout << "----------------------------------------" <<endl;
 cout << "Enter 3 to convert from inch to meters" <<endl;
 cout << "----------------------------------------" <<endl;
 cout << "Enter 0 to exit" << endl;
 cout << "****************************************" <<endl;
 cin >> option;
 
 //end here
 
 // select kind of calc
 cout << "Enter the length" <<endl;
 cout << "----------------" <<endl;
  cin >> number;
 
 //start calc here
 
 switch (option)
 {
 case 0:
 return (0);
 case 1:
 result = ( number * 0.9144 );
 break;
 case 2:
 result = ( number * 0.3048 );
 break;
 case 3:
 result = ( number * 0.0254 );
 break;
 }
 cout << "The result of the converstion is: " << result <<endl;
  
 system("PAUSE");	
 return 0;

You need to put the switch before you input number.

Edit: Actually, that would cause a problem, because you would be performing all the calculations before you enter number. Instead of testing for 0 in the switch, take it out and put an if statement before you enter number to test for 0. Leave the switch statement where you originally had it.

Well everything works correctly except the case 0 part.

Check the edit. That should do it.

Perfect.

 cout << "****************************************" <<endl;
 cin >> option;
 
 //end here
 
 // select kind of calc
 cout << "Enter the length" <<endl;
 cout << "----------------" <<endl;
 if (option == 0 )return (0);
 cin >> number;
 
 //start calc here
 
 switch (option)
 {
 case 1:
 result = ( number * 0.9144 );
 break;
 case 2:
 result = ( number * 0.3048 );
 break;
 case 3:
 result = ( number * 0.0254 );
 break;
 }
 cout << "The result of the converstion is: " << result <<endl;
  
 system("PAUSE");	
 return 0;
}

Thanks....
