Question

#include <stdio.h> #include <stdlib.h> #include <conio.h>

display

why no of array elements not getting change while traversing array elements all initial no of elements get printed only

 int display_array(int arr[], int n) { int i; for (i = 0; i < n; i++) { printf("arr[%d] = %d\\n", i, arr[i]); } return 0; }

insertion

 int insert_position(int arr[], int n) { int i = 0, pos, num; printf("Enter the number to be inserted:\\n"); scanf("%d", &num); printf("enter the pposition at which the number is to be inserted:\\n"); scanf("%d", &pos); for (i = n - 1; i >= pos; i++) { arr[i + 1] = arr[i]; } arr[pos] = num; n = n + 1; return 0; }

deletion

 int delete_position(int arr[], int n) { int i = 0, pos; printf("Enter the position from which the number has to be deleted:\\n"); scanf("%d", &pos); for (i = pos; i < n - 1; i++) { arr[i] = arr[i + 1]; } n = n - 1; return 0; }

Answer 1

I think you are passing those parameters in these functions as pass by value, not pass by reference . That's why initial values are printing every time you are calling them. You can use pointers, or you can use global variables to get the desired result.
