Thread: Help me

that code looks suspiciously like the code from Need help on making a menu system for my program
since you are copying someone else's work, just copy from that link.

It is i used it to do the menu but cant figure out how to do the conversions

google 'miles to kilometers' etc and it will tell you what to do

Ive tried adding a miles to kilometres conversion but cant get it to run properly

Code:

#include <stdio.h>#include<stdlib.h>


int menu();
int distance();
int sw;
int main()
{
    menu();
    float value;
    value=distance();
    printf("%f", value);
    return 0;


}




int menu()
{
system("cls");


printf(" Please selcet a category\n");
printf(" 1.Weight\n");
printf(" 2.Measurement\n");
printf(" 3.Distance\n");
printf(" 4.Tempereture \n ");
sw=getch();
sw=sw-'0';
switch(sw)
{
case 1:
//code....
break;




case 2:
//...
break;




case 3:
distance();
break;




case 4:
//...
break;




default:
menu();
break;
}
}
int distance()
{
system("cls");
printf(" 1.Miles to kilometres\n");
printf(" 2.Kilomeres to miles\n");
printf(" 3.Return to the Main menu\n");
sw=getch();
sw=sw-'0';
switch(sw)
{
case 1:
MtoK();
break;




case 2:
//code...
break;




case 3:
main();
break;




default:
distance();
break;
}
}
int MtoK()
{
float miles, kilometres;
system("cls");
printf("\t\tMiles to Kilometres Conversion\n");
printf("\t\t------------------------------\n");
printf("\t\tEnter number of Miles: ");
kilometres=miles/0.621371192;


printf("\t\t%2.2f mile(s) == %2.2f kilometre(s)",miles, kilometres);
printf("\n\n\tPress enter to return to the Main Menu");
getchar();
          return kilometres;
}

Line 106--> what is miles value? You need to properly initialize it. As of right now miles holds some outrageous random value that was in that memory slot.
