Answer 1

#include<stdio.h>




int main(){
	int i=0;
	int index=0;
	int size=0;
	int oddSum=0;
	int target=0;
	int elements[1000];




	int ch=-1;


	while(ch!=8){
		printf("1. Insert\n");
		printf("2. Delete\n");
		printf("3. Display\n");
		printf("4. Search\n");
		printf("5. Display the multiple of two\n");
		printf("6. Calculate the sum of odd elements\n");
		printf("7. Display the elements in the reverse order\n");
		printf("8. Exit\n");	
		scanf("%d",&ch);
		switch(ch){
		case 1:
			{
				printf("Enter element: ");
				scanf("%d",&elements[size]);
				size++;
			}
			break;
		case 2:
			{
				printf("Enter index of element to delete [0,%d]: ",(size-1));
				scanf("%d",&index);
				for(i=index;i<size-1;i++){
					elements[i]=elements[i+1];
				}
				size--;
				printf("\nThe element has been deleted.\n");
			}
			break;
		case 3:
			{

				for(i=0; i<size; i++){

				}
				printf("\n");
			}
			break;
		case 4:
			{
				printf("Enter the element to search: ");
				scanf("%d",&target);
				for(i=0; i<size; i++){

					}
