VALUE INSERTION IN THE ARRAY(MODIFIED)

• Problem Description

  Write a program using pointers to insert a value in an array.
  Input and Output Format:
  Refer sample input and output for formatting specification.
  All float values are displayed correct to 2 decimal places.
  All text in bold corresponds to input and the rest corresponds to output.

• CODING ARENA

• #include <stdio.h>

  int main()

  {

     int j,i,n,b;

     scanf("%d", &n);

     int a[n];

     for (i=0;i<n;i++){

        scanf("%d",&a[i]);

     }

     scanf("%d", &b);

     scanf("%d", &j);

     for (i=n-1;i>=j-1;i--)

     {

        a[i+1] = a[i]; }

        a[j]=b;

     for (i=0;i<=n;i++){

        printf("%d\n",a[i]);

     }

     return 0;

  
  

  }
