Question

I need help figuring out how to create a header file that will work with the main file in a c. compiler program. Im using codeblocks. Screenshots greatly appreciated.

I need help with a code that can create functions for different types of multiplications, and using a header file to call the variables for the function.

This is a screenshot of the project im working on, any help to get started, or to finish would help. Thank you!

Explanation / Answer

How to create a header file that will work with the main file in a c.

Step1 : Type this Code

int add(int a,int b)

{

return(a+b);

int add(int a,int b)

{

return(a+b);

}

In this Code write only function definition as you write in General C Program

Step 2 : Save Code

Save Above Code with [.h ] Extension .

Let name of our header file be myhead [ myhead.h ]

Compile Code if required.

Step 3 : Write Main Program

#include<stdio.h>

#include"myhead.h"

void main() {

int num1 = 10, num2 = 10, num3;

num3 = add(num1, num2);

printf("Addition of Two numbers : %d", num3);

}

#include<stdio.h>

#include"myhead.h"

void main() {

int num1 = 10, num2 = 10, num3;

num3 = add(num1, num2);

printf("Addition of Two numbers : %d", num3);

}

Include Our New Header File .

Instead of writing < myhead.h> use this terminology “myhead.h”

All the Functions defined in the myhead.h header file are now ready for use .

Directly call function add(); [ Provide proper parameter and take care of return type ]

Note

While running your program precaution to be taken : Both files [ myhead.h and sample.c ] should be in same folder.

================================================

If you want to add some external header files, then:
1. Go to project->build options.
2. "search directories"
3. "compilers" sub tab.
4. Click add, select the file and you are done.
