How to write a C program to Linked list implementation for printing the employee details, display them and SEARCH for the salary of the employee based on his designation in C Programming Language ?
Solution:
/* Linked list implementation for printing the employee details, display them and SEARCH for the salary of the employee based on his designation */
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
struct node* createnode(struct node*);
void display(struct node*);

float salary;
struct node* ptr;
};
int main()
{
struct node* head;
int b,i;
head=NULL;
while(1)
{
printf("\nEnter the value\n1-> to enter the employee details\n2->to display the results\n3->to search an element\n");
scanf("%d",&b);
switch(b)
{
case (1): printf("\nEnter the number of employee details you would like to enter\n");

while(i>0)
{

}

}
}
}
