Array CODE

Array Codes
1A. Write a program to store the elements in 1-D array and perform the
operations like searching, sorting and reversing the elements. [Menu Driven]
#include <stdio.h>
#include <stdlib.h>
void bubble_sort(int b[], int n);
void reverse(int b[], int n);
void search(int b[], int n);
void main(){

    n = 7;
    printf("\n A : ");
    for (i = 0; i < n; i++)
        printf("\t %d", a[i]);
    while (ch != 4) {
        printf("\n 1.Sort \n 2.Reverse \n 3.Searching \n 4.Exit \n Select the option : ");
        scanf("%d", &ch);
        switch (ch) {
            case 1:
                bubble_sort(a, n);
                break;

    printf("\n Array : ");
    for (i = 0; i < n; i++)
        printf("\t %d", b[i]);

    printf("\n \n Reversed Array : ");
    for (i = n - 1; i >= 0; i--)
        printf("\t %d", b[i]);
}

    int data, i, flag = 0;
    printf("\n Array : ");
    for (i = 0; i < n; i++)
        printf("\t %d", b[i]);
    printf("\nEnter element to search: ");

            break;
        }
    }
    if (flag == 0) {
        printf("\n The element is not present in the array!!");
    }
}

elements in sorted order. [Menu Driven]
