• Problem Description

  
  Write a program to compare two arrays using pointers.
  
  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.

• Test Case 1

  
  Input (stdin)

  5
  
  1 2 3 4 5
  
  5
  
  5 4 3 2 1
  
  

  Expected Output

  Arrays are not equal

• Test Case 2

  
  Input (stdin)

  4
  
  1 2 3 4
  
  4
  
  1 2 3 4
  
  

  Expected Output

• Program

• #include <stdio.h>
  int main()
  {
    int a,b,i,j,f;
    scanf("%d",&a);
    int arr[a];
    for(j=0;j<a;j++)
    {
      scanf("%d",&arr[j]);
    }
    scanf("%d",&b);
    int arr1[b];
    for(i=0;i<b;i++)
    {
      scanf("%d",&arr1[i]);
    }
    for(i=0;i<a;i++)
    {
      if(arr[i]!=arr1[i])
      {
        f=1;
        break;
      }
    }
    if(f==1)
      printf("Arrays are not equal");
    else
      printf("Arrays are equal");
      
                   
      
  
   return 0;
  }
