October 4 Write a C program to print all permutations of a given string

A permutation, also called an “arrangement number” or “order,” is a rearrangement of the elements of an ordered list S into a one-to-one correspondence with S itself. A string of length n has n! permutation. Below are the permutations of string ABC. ABC, ACB, BAC, BCA, CAB, CBA Here is a solution using backtracking. // C program to print all permutations with duplicates allowed #include <stdio.h> #include...

September 23 Enter and print details of n employees using structures and dynamic memory allocation

 Enter and print details of n employees using structures and dynamic memory allocation This program is used to show the most basic use of structures. The structure is made of a character array name[], integer age and float salary. We’ll make an array of the structure for the employees. We’ll also use dynamic memory allocation using malloc. You can also use a linked list to the same which is a better option. Let’s check the code. ? #include #include typedef struct{ //structure of emp  char name[30];  int age;  float salary; }emp; int main(){  int n,i;  emp *employee;  printf("Enter no of...
