Program Code – Mastering the C Programming Language for System and Application Development
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
// Define a struct for Employee
typedef struct {
char name[50];
int age;
char position[50];
float salary;
} Employee;
// Function prototypes
void addEmployee(Employee *e, char *name, int age, char *position, float salary);
void displayEmployees(Employee *e, int count);
int main() {
int count = 0;
printf('Enter the number of employees: ');
scanf('%d', &count);
getchar(); // consume the newline character
Employee *employees = (Employee *)malloc(count * sizeof(Employee));
for (int i = 0; i < count; i++) {
char name[50];
int age;
char position[50];
float salary;
printf('Enter employee name: ');
fgets(name, 50, stdin);
name[strcspn(name, '
')] = 0; // remove the newline character
printf('Enter employee age: ');
scanf('%d', &age);
getchar(); // consume the newline character
printf('Enter employee position: ');
fgets(position, 50, stdin);
position[strcspn(position, '
')] = 0; // remove newline
printf('Enter employee salary: ');
scanf('%f', &salary);
getchar(); // consume the newline character
addEmployee(&employees[i], name, age, position, salary);
}
displayEmployees(employees, count);
free(employees); // Free the allocated memory
return 0;
}
void addEmployee(Employee *e, char *name, int age, char *position, float salary) {

e->age = age;
strcpy(e->position, position);
e->salary = salary;
}
void displayEmployees(Employee *e, int count) {
printf('
Employee Details:
');
for (int i = 0; i < count; i++) {
printf('Name: %s, Age: %d, Position: %s, Salary: %.2f
', e[i].name, e[i].age, e[i].position, e[i].salary);
}
}
Code Output:
Enter the number of employees: 2
Enter employee name: John Doe
Enter employee age: 30
Enter employee position: Developer
Enter employee salary: 50000
Enter employee name: Jane Doe
Enter employee age: 28
Enter employee position: Designer
Enter employee salary: 45000
Employee Details:
Name: John Doe, Age: 30, Position: Developer, Salary: 50000.00
Name: Jane Doe, Age: 28, Position: Designer, Salary: 45000.00
Code Explanation:
The program starts by including standard input-output and string libraries in C, then it defines a struct for Employee with name, age, position, and salary as attributes. A structure is a user-defined data type in C programming which allows us to combine data items of different kinds.
Two function prototypes, addEmployee() and displayEmployees(), are declared for later use.
The main() function prompts the user to input the number of employees. It then allocates memory dynamically for the array employees using malloc(), based on the input count. This is to store each employee’s details.
For each employee, the program captures name, age, position, and salary from the user. The fgets() function is used to read strings to also capture spaces, and scanf() is used for integers and floats. The newline character left in the input buffer by scanf() is consumed using getchar() to avoid it being captured by the subsequent fgets() call, which would otherwise lead to skipping inputs. The strcspn() function is used to remove newline characters captured by fgets().
The addEmployee() function is called to populate each employee struct with the captured details. This function uses strcpy() to copy strings and directly assigns integer and float values.
After all employees have been added, the displayEmployees() function is called to iterate over the array and print each employee’s details. Finally, the dynamically allocated memory for employees is freed using free(), adhering to good memory management practices.
This program showcases fundamental aspects of the C programming language such as dynamic memory allocation, user-defined data types (structures), input/output, and string handling, making it a quintessential example for mastering C for system and application development.
