#include<string.h>

typedef struct employee{

    int code;

    float salary;

    char name[20];

} emp;

void show(emp emp1){

    printf("The Code of employee is: %d\n", emp1.code);

    printf("The Salary of employee is: %f\n", emp1.salary);

    printf("The Name of employee is: %s\n", emp1.name);

    

}

int main(){

    // Declaring e1 and ptr

    emp e1;

    emp *ptr;

    // pointing ptr to e1

    ptr = &e1; 

    // Set the member values for e1

    ptr->code = 101;

    ptr->salary = 11.01;

    strcpy(ptr->name, "Harry"); 

    show(e1);

    return 0;
