C program to pass a structure to a user define function

Given a structure and we have to pass it to a function in C.

structure declaration is:

struct exam
{
    	int marks;
    	char name[20];
};

Here,

  • exam is the structure name
  • marks and name are the members of the structure/variable of the structure

Here is the function that we are using in the program,

void structfun(struct exam obj1);

Here,

  • void is the returns type of the function i.e. function will not return any value.
  • structfun is the name of the function.
  • struct exam obj1 is the object of exam structure - while declaring a function we must have to use struct keyword with the structure name.

Structure object/variable declaration is:

    struct exam obj;

Assigning values to the structure variable inside the main

    obj.marks = 50;
    strcpy(obj.name , "Arjun kapoor");

Function calling statement,

structfun(obj);

// define the structure by declaring the global object
struct exam obj;

 // declaration of the function
void structfun(struct exam obj1);

// function to print structure elements
void structfun(struct exam obj1)
{
    printf("\nThe name of the student is : %s",obj1.name);
    printf("\nThe marks of the student is : %d",obj1.marks);
}

// main function
int main()
{
    obj.marks = 50;
    strcpy(obj.name , "Arjun kapoor");
	
    // Passing structure to Function
