Thread: Little converter problem

Code:

#include <iostream.h>

using namespace std;
void gl();
void lg();
void mk();
void km();
void pk();
void kp();


int a;

int main()
{
    cout << "Choose the converter you want (1-6): \n";
    cout << "1: Gallons to liters. \n";
    cout << "2: Liters to gallons. \n";
    cout << "3: Miles to kilometers. \n";
    cout << "4: Kilometers to miles. \n";
    cout << "5: Pounds to kilograms. \n";
    cout << "6: Kilograms to pounds. \n";
    cout << "\n";
    cin >> a;
    
    switch(a){
    case 1: gl();
    case 2: lg();
    case 3: mk();
    case 4: km();
    case 5: pk();
    case 6: kp();
            }
}
// Gallons to liter converter

void gl()
{
float liters;
float gallons;

    {
          
          cout << "Input gallons. \n";
          cin >> gallons;
     liters = gallons * 3.7854118;
          cout << "Liters:" << liters;
     }
     
}

// Kilograms to pounds converter

void kp()

float lbs;
float kg;

{
    {
          
          cout << "Input kilograms. \n";
          cin >> kg;
     float lbs = kg * 2.20462262;
          cout << "Pounds:" << lbs;
     }
     
}

// Kilometers to miles converter

void km()

float kilometers;
float miles;


{
    {
          
          cout << "Input kilometers. \n";
          cin >> kilometers;
     miles = kilometers * 1.609344;
          cout << "Miles:" << miles;
     }
     
}

// Liters to gallons converter

void lg()

float liters;
float gallons;

{
    {
          
          cout << "Input liters. \n";
          cin >> liters;
     gallons = liters * 0.264172051;
          cout << "Gallons:" << gallons;
     }
     
}

// Pounds to kilograms converter

void pk()

float lbs;
float kg;

{
    {
          
          cout << "Input pounds. \n";
          cin >> lbs;
     kg = lbs * 0.45359237;
          cout << "Kilograms:" << kg;
     }
     
}

// Miles to kilometers converter

void mk()

float kilometers;
float miles;

{
    {
          
          cout << "Input miles. \n";
          cin >> miles;
     kilometers = miles * 0.621371192;
          cout << "Kilometers:" << kilometers;
     }
     
}

I keep getting syntax errors every time compile it. Each converter works alone, but I cant seem to get them to work together.

Post your styntax errors.

edit:

First of all, remove the .h from iostream, and add a "break;" statement after each case in your switch.

Oops, sorry. Here they are:

EDIT: Adding break and taking away the .h fixed the errors about the "not in switch statement"

>void kp()

>float lbs;
>float kg;

>{

The beginning function brace goes before any local declarations:

Code:

void kp()
{
float lbs;
float kg;

You did that on just about every function.
