C Program to Store Information of 10 Employees Using Structure

Objective

Write a C program to store information of 10 Employees using an Array of Structures.

Algorithm / Approach

  1. Define struct Employee.
  2. In main(), declare an array of structures: struct Employee s[10].
  3. Run a loop from 0 to 9.
  4. Inside the loop, access each employee's data using the array index and the dot operator: s[i].name and &s[i].salary.
  5. Use a second loop to print out all the stored data.
main.c 
#include<stdio.h>
struct Employee{
 char name[50];
 int id;
 float salary;
};
int main( ){
 struct Employee s[10];
 int i;
 printf("Enter Info of Emps : \n");
 for(i=0;i<10;++i)  {
  s[i].id=i+1;
  printf("\nFor id number %d\n",s[i].id);
  printf("Enter name: ");
  scanf("%s",s[i].name);
  printf("Enter salary: ");
  scanf("%f",&s[i].salary);
  printf("\n");
 }
 printf("Information of Emps:\n");
 for(i=0;i<10;++i) {
  printf("Info for id number %d:\n",i+1);
  printf("Name : ");
  puts(s[i].name);
  printf("salary : %.1f",s[i].salary);
 }
 return 0;
}

Expected Output

Enter Info of Emps : 
For id number 1
Enter Name : xyz
Enter Salary : 5000
For id number 2
Enter Name : abc
Enter Salary : 15000
.
.
Information of Emps :
Info for id number 1
Name : xyz
Salary : 5000
Name : abc
Salary : 15000
.
.

Explanation of the Program

  • An Array of Structures is incredibly powerful. Instead of making 10 separate variables (s1, s2, s3...), we make an array of size 10.
  • Each slot in the array (e.g., s[0]) holds a complete Employee structure, allowing us to easily process hundreds of records using a simple loop, just like a database table.

Complexity

Time Complexity O(n) - Where n is the number of employees (10).
Space Complexity O(n) - Array of 10 structures.
