Passing Structure to Function in C Programming

You can pass a structure variable to a function as argument like we pass any other variable to a function. Structure variable is passed using call by value. We can also pass individual member of a structure as function argument.

C Program to Pass Structure Variable to Function

In below program, we are passing a member variable to printAge function and whole structure variable to printEmployeeDetails function.

#include <stdio.h>
#include <conio.h>

struct employee {
    char name[100];
 int age;
 float salary;
 char department[50];

void printEmployeeDetails(struct employee emp){
   printf("Employee Details\n");
   printf(" Name : %s\n Age : %d\n Salary = %f\n Dept : %s\n",, emp.age, emp.salary, emp.department);

void printAge(int age){
    printf("\nAge = %d\n", age);

int main(){
   struct employee employee_one, *ptr;
   printf("Enter Name, Age, Salary and Department of Employee\n");
   scanf("%s %d %f %s", &, &employee_one.age,
       &employee_one.salary, &employee_one.department);
   /* Passing structure variable to function */
   /* Passing structure member to function */

   return 0;

Program Output
Enter Name, Age, Salary and Department of Employee
Rose 35 1234.5 Purchase
Employee Details
 Name : Rose
 Age : 35
 Salary = 1234.500000
 Dept : Purchase
Age = 35
