Write a C program to implement the following: 1. Take an int array of 100 elements. Populate it using random number generator built-in function. 2. User will be given the following choices: a) To insert a new element in the array. b) To delete an element in the array. c) To search an item in the array. d) To update an item in the array. e) To show the elements of the array. f) To quit from the program.
#include <stdio.h>
#include <conio.h>
#include <iostream.h>
int main()
{
int i, a[100], loc, item, size=99;
char option;
for(i=0; i<=size; i++)
{
a[i]= rand() % 20;
}
printf("Press a, b, c, d, e, f\na) To insert a new element in the array. \nb) To delete an element in the array. \nc) To search an item in the array. \nd) To update an item in the array. \ne) To show the elements of the array. \nf) To quit from the program.");
