Problem: Write a C++ program to take the number n and an array A of n numbers as input from the user. The program should then contain a function which determines whether the array is in strictly increasing order (in which case the function should return 1), or else determine whether the array is in strictly decreasing order (in which case the function should return 2), and return 3 otherwise. The format of the function is int isIncreasingDecreasing (int *A, int n). The program should then print the value returned by the function on a new line. You must implement this via a function, otherwise you will get no credit. For simplicity, assume that all entries in the array are unique.

Input Format - Non-negative integer n and an array A of n elements
Output Format - The value 1,2 or 3 as described above.

Problem: Write a C++ program to take the number n and an array A of n numbers as input from the user. The program should then contain a function which determines whether the array is in strictly increasing order (in which case the function should return 1), or else determine whether the array is in strictly decreasing order (in which case the function should return 2), and return 3 otherwise. The format of the function is int isIncreasingDecreasing (int *A, int n). The program should then print the value returned by the function on a new line. You must implement this via a function, otherwise you will get no credit. For simplicity, assume that all entries in the array are unique.

Input Format - Non-negative integer n and an array A of n elements
Output Format - The value 1,2 or 3 as described above. 
Constraints
1 <= n < 25

Sample input - 33 4 2
Sample output - 3

Student submission:
#include<iostream>
using namespace std;
int isIncreasingDecreasing(int* a,int n){
cin>>n;
for(int i =0;i<n;i++){
cin>>a[i];}
for(int i=0;i<n-1;i++){
 if (a[i]<a[i+1])
 cout<<"1";}
for(int i=0;i<n-1;i++){
 if  (a[i]>a[i+1])
  cout<<"2";
  else cout<<"3";}
 return 0;
 }
 int main(){
  int n,*a;
  isIncreasingDecreasing(a,n);{
   }
   cout<<"2";
   }
