Thread: 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

3rd Code: Multiplication of Matrices

Code:

#include<stdio.h> 
#include<conio.h> 
void main() 
{ 
int mat1[2][2],mat2[2][2],mat3[2][2],i,j,k;
clrscr();
printf("************A program to find the multiplication of the given matrices***********\n\n"); 
printf("************Enter the value for the 1st matrix************\n"); 
for(i=0;i<2;i++) 
{ 
for(j=0;j<2;j++) 
{ 
printf("\nEnter the value for %d row,%d column:",i+1,j+1); 
scanf("%d",&mat1[i][j]); 
} 
} 
printf("\n************Enter the value for the 2nd matrix************\n"); 
for(i=0;i<2;i++) 
{ 
for(j=0;j<2;j++) 
{ 
printf("\nEnter the value for %d row,%d column:",i+1,j+1); 
scanf("%d",&mat2[i][j]); 
} 
} 
printf("\n****************************The given matrices are*****************************\n\n"); 
for(i=0;i<2;i++) 
{ 
for(j=0;j<2;j++) 
{ 
printf("%d\t",mat1[i][j]); 
} 
printf("\n"); 
} 
printf("\n\n"); 
for(i=0;i<2;i++) 
{ 
for(j=0;j<2;j++) 
{ 
printf("%d\t",mat2[i][j]); 
} 
printf("\n"); 
} 
printf("\n****************************The multiplication of the matrices is*************\n\n"); 
for(i=0;i<2;i++) 
{ 
for(j=0;j<2;j++) 
{ 
mat3[i][j]=0; 
for(k=0;k<2;k++) 
{ 
mat3[i][j]=mat3[i][j]+(mat1[i][k]*mat2[k][j]); 
} 
} 
} 
for(i=0;i<2;i++) 
{ 
for(j=0;j<2;j++) 
{ 
printf("%d\t",mat3[i][j]); 
} 
printf("\n"); 
} 

getch(); 
getch(); 
}

you don't with 3 mains, hows it gonna know what to do if you were to start it

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)?

Thank you very much i already solved my problem

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>
