1. Data Structure Program | Read Now
Data Structure LAB program -01
- Design, Develop and Implement a menu-driven Program in C for the following Array operations
- Creating an Array of N Integer Elements
- Display of Array Elements with Suitable Headings
- Inserting an Element (ELEM) at a given valid Position (POS)
- Deleting an Element at a given valid Position(POS)
- Exit.
- Support the program with functions for each of the above operations.
Program 1 Code [array.c]
Save the file with .c extension
#include<stdio.h> #include<stdlib.h> int a[10],n,elem,i,pos; void create(); void display(); void insert(); void delete(); void create() { int i; printf("Enter the size of array\n"); scanf("%d",&n); printf("Enter the elements of array\n"); for(i=0; i<n; i++) scanf("%d",&a[i]); } void display() { int i; printf("The array elements are:\n"); for(i=0; i<n; i++) printf("%d\t",a[i]); } void insert() { int i; printf("Enter the position for new element:\n"); scanf("%d",&pos); printf("Enter the element to be inserted:\n"); scanf("%d",&elem); for (i = n-1; i <=pos; i--) a[i+1]=a[i]; a[pos]=elem; n=n+1; } void delete() { printf("Enter position of element to be deleted:\n"); scanf("%d",&pos); elem=a[pos]; for (int i = 0; i < n-1; i++) a[i]=a[i+1]; n=n-1; printf("Deleted element is %d\n",elem ); } int main() { int ch; while(ch) { printf("\n\n______MENU_____\n"); printf("1.Create\n2.Display\n3.Insert\n4.Delete\n5.Exit\n"); printf("Enter Your Choice:"); scanf("%d",&ch); switch(ch) { case 1:create();break; case 2:display();break; case 3:insert();break; case 4:delete();break; case 5:exit(0);break; default :printf("INVALID CHOICE\n"); } }return 0; }
