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);

Program to pass a structure to a function in C

/* C program to a structure to a function */ #include <stdio.h> // Declare a global structure since we need to pass // it to a function struct exam { int marks; char name[20]; }; // 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 structfun(obj); return 0; }

Output

The name of the student is : Arjun kapoor The marks of the student is : 50
