Discussion: Files with .h extension are called header files in C. These header files generally contain function declarations which we can be used in main C program, like for e.g. to include stdio.h in C program to use function printf() Exercise 2. Creating myhead.h : Write the below code and then save the file as myhead.h or you can give any name but the extension should be .h indicating it’s a header file. // It is not recommended to put function definitions // in a header file. Ideally there should be only // function declarations. Purpose of this code is // to only demonstrate working of header files. void add(int a, int b) { printf("Added value=%d\n", a + b); } void multiply(int a, int b) { printf("Multiplied value=%d\n", a * b); } Including the .h file in other program : Now as we need to include stdio.h as #include in order to use printf() function. We will also need to include the above header file myhead.h as #include”myhead.h”. The ” ” here are used to instruct…
