Please complete option 3.

Answer 1

C CODE:

#include <stdio.h>
#include <stdlib.h> //for exit
int main() {
    int n,i; //declaring size variable of array as n and iterator as i
    printf("Enter size of array: ");
    scanf("%d",&n);//input size of array
    int arr[n];//making array
    while(1){ //for infinite loop till exit
    printf("*Press 1 to Enter Data in array \n");
    printf("*Press 2 to Print Data of array \n");
    printf("*Press 3 to Clear Data of array \n");//for clearing data make all 0
    printf("*Press 0 to EXIT  \n");
    int choice;
    scanf("%d",&choice);//inputting choice
    switch(choice)
    {
        case 1:
            printf("\nEnter %d values to insert into array:\n",n);
            for(i=0;i<n;i++)
            {
                scanf("%d",&arr[i]); //inputting values in array
            }
            printf("\n");
            break;
        case 2:
            printf("\nHere are your %d elements of array:\n",n);
            for(i=0;i<n;i++)
            {
                printf("%d ",arr[i]); // outputting array values
            }
            printf("\n\n");
            break;
        case 3:
            for(i=0;i<n;i++)
            {
                arr[i]=0; //clearing values of array by putting 0 at every place
            }
            printf("\nSucessfully cleared data in array:\n\n",n);
            break;
        case 0:
            exit(0); //to exit the program
        default:
            printf("Invalid Input");}} // to handle case other than 0 1 2 
    return 0;}
