Array Deletion

• Problem Description

  
  Write a program to delete an element from the array.
  
  Input and Output Format:
  
  Assume that the maximum number of elements in the array is 20.
  
  Refer sample input and output for formatting specifications.
  
  All text in bold corresponds to input and the rest corresponds to output.
  
  Input:
  1. The number of inputs to be entered by the user
  2. The array elements
  3. The array index to be deleted
  
  
  Example 1:
  Input 1:
  4
  11 12 13 14
  1
  
  Output 1:
  Array after deletion is
  11 13 14
  
  Explanation:
  Array Index starts from 0 the user entered array index as 1 so the number 12 is deleted.
  arr[0]=11
  arr[1]=12
  arr[2]=13
  arr[3]=13
  
  Deleted Element=12 a[1]
  
  

• Test Case 1

  
  Input (stdin)

  5
  
  14 25 13 34 45
  
  4
  
  

  Expected Output

  Array after deletion is
  
  14 25 13 34

• Test Case 2

  
  Input (stdin)

  5
  
  1 2 3 4 5
  
  2
  
  

  Expected Output

  Array after deletion is
  
  1 2 4 5

Solution

#include<stdio.h>

 

int main() 

{

    int a[100],i,n,pos;   

    scanf("%d",&n);

    

    

    for (i=0;i<n;i++) 

    {

        scanf("%d",&a[i]);

    }

    

    

 

   

    scanf("%d",&pos);

    for(i=pos;i<n-1;i++)

    {

        a[i]=a[i+1];

    }

    n=n-1;

    printf("Array after deletion is\n");

    for(i=0;i<n;i++) 

    {

        printf("%d ",a[i]);

    }

  return 0;

}
