Question

For this homework, you will use multiple source files. The file descriptions are below. Make sure to use the correct include statements in all files. Submit only the .c and .h files.

• multiple.h - This file will include the function prototypes for two functions. Include the prototypes within an include guard.

  • void printUpTriangle(int x);

  • void printDownTriangle(int x);

• main.c - This file will include the main function. In main, prompt the user for a positive integer and then call both functions with the integer typed.
• multple.c - Implement the functions for the prototypes above. The functions will print asterisk triangles. Some sample calls are shown below.

printUpTriangle(3);

printUpTriangle(5);

Answer 1

multiple.h

#ifndef _MULTPLE_H
#define _MULTPLE_H
#include<stdio.h>
void printUpTriangle(int x);
void printDownTriangle(int x);
#endif

multple.c

#include"multple.h"
#include<stdio.h>
void printUpTriangle(int x)
{
   int i,j;
   for(i=0;i<x;i++)
   {
       for(j=0;j<=i;j++)
       {
           printf("*");
       }
       printf("\n");
   }
}
void printDownTriangle(int x)
{
   int i,j;
   for(i=x;i>0;i--)
   {
       for(j=i;j>0;j--)
           printf("*");
       printf("\n");
   }
}

main.c

#include"multple.h"
int main()
{
   printUpTriangle(3);
   printf("\n\n");
   printUpTriangle(5);
   printf("\n\n");
   printDownTriangle(3);
   printf("\n\n");
   printDownTriangle(5);
   printf("\n\n");
   return 1;
}
