C program to pass an array of structure to a user-defined function

Given an array of structure and we have to pass it to the function in C.

structure declaration is:

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

Here,

• exam is the structure name
• roll, 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[2];

obj is an array of structure for 2 structures.

Assigning values to the structure variables (array of structure variables) inside the main()

    // assign values using the object 1
    obj[0].marks = 35;
    obj[0].roll = 10;
    strcpy(obj[0].name , "Arjun kapoor");
	
    // assign values using the object 1
    obj[1].marks = 75;
    obj[1].roll = 11;
    strcpy(obj[1].name , "Balram chauhan");

Function calling statement,

structfun(obj);
