    How Can I compile 3 source code in 1 program ?

    1. I'm wondering how to compile this 3 source code in 1 program using case statement coz im having difficult to make it in 1 combined program..
    i hope somebody could help me thanks ...

    example :

    [1] Sound
    [2] Fibonacci numbers
    [3] Multiplication of Matrices

    please select a number:


    1st code: Sound
    Code:
    #include <dos.h>
    #include <stdio.h>
    #include <stdlib.h>
    
    int menu(void);
    
    
    main()
    {
    while(1)
    {
    /*get selection and execute the relevant statement*/
    switch(menu())
    {
    case 1:
    {
    puts("sound the speaker 1\n");
    sound(2000);
    sleep(2);
    nosound();
    break;
    }
    case 2:
    {
    puts("sound that speaker 2\n");
    sound(4000);
    sleep(2);
    nosound();
    break;
    }
    case 3:
    {
    puts("You are quitting\n");
    exit(0);
    break;
    }
    default:
    {
    puts("Invalid menu choice\n");
    break;
    }
    }
    }
    return 0;
    }
    
    /*menu function*/
    int menu(void)
    {
    int reply;
    /*display menu options*/
    puts("Enter 1 for beep 1.\n");
    puts("Enter 2 for beep 2.\n");
    puts("Enter 3 to quit.\n");
    /*scan for user entry*/
    scanf("%d", &reply);
    
    return reply;
    }
    2nd code: Fibonacci numbers
    Code:
    #include <stdio.h>
    
    int main(void) {
        int n;        /* The number of fibonacci numbers we will print */
        int i;        /* The index of fibonacci number to be printed next */ 
        int current;  /* The value of the (i)th fibonacci number */
        int next;     /* The value of the (i+1)th fibonacci number */
        int twoaway;  /* The value of the (i+2)th fibonacci number */
    
        printf("How many Fibonacci numbers do you want to compute? ");
        scanf("%d", &n);
        if (n<=0)
           printf("The number should be positive.\n");
        else {
          printf("\n\n\tI \t Fibonacci(I) \n\t=====================\n");
          next = current = 1;
          for (i=1; i<=n; i++) {
     printf("\t%d \t   %d\n", i, current);
     twoaway = current+next;
     current = next;
     next    = twoaway;
          }
        }
    return 0;
    }
    
    /* The output from a run of this program was:
    
    How many Fibonacci numbers do you want to compute? 9
    
     I   Fibonacci(I) 
     =====================
     1     1
     2     1
     3     2
     4     3
     5     5
     6     8
     7     13
     8     21
     9     34
    
    */

    what compiler/IDE you are using
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

    In Visual C++, you'd add the source files into the section on the left side containing the project/solution. You'd then include them and have a single "int main()" within the project. It's here that you include the other codes (removing redundant includes).

    #include "first source.c"
    #include "second source.c"
    #include <stdio.h> // only one instance needed
    #include <dos.h>
    // and so on

    This way, you can keep them separate. They can also all be merged into one single script as I tend to do (to a certain point), but you'd need to remove duplicate includes and global variable declarations (of which you lack global variables).

    Yeah, generally like that. Just make sure you've copied everything as needed and didn't leave anything out. I'm no expert as I'm learning myself, but there's often several ways to solve a particular problem. Does it compile and run successfully (excluding bugs, except crashers)?

    more over think of changing your compile. That is one of ancient 16bit compiler. probably u might running it on 32bit machine. Try DEV-C++ or Borland C. I can also see some non standard library used in your code <conio.h>
