Write a program that reads the dimension N1 and N2 of two integer arrays T1 and T2 (maximum dimension: 50 components), fills the arrays with values entered on the keyboard and displays the array.

The program then indicates if these two arrays are identical or not.

Examples:

  • T1={4, 5, 7, 8, 4} and T2={7, 5, 4, 8} are identical
  • T1={4, 5, 7, 8, 4} and T2={7, 5, 4, 8, 0} are not identical 

Difficulty level
This exercise is mostly suitable for students
#include<stdio.h>
#include<math.h>
#include<conio.h>
#define SIZE 50
void main()
{
	int N1, N2; // nb of elements
	int T1[SIZE], T2[SIZE]; // arrays of maximum size 50
	int i, j, found;
	do {
		printf("Enter N1: ");
		scanf("%d", &N1);
	} while (N1<0 || N1>SIZE);

	for (i = 0; i < N1; i++)
	{
		printf("Enter T1[%d]: ", i);
		scanf("%d", &T1[i]);
	}

	printf("\n\nPrinting the elements of T1\n");
	for (i = 0; i < N1; i++)
	{
		printf("T1[%d]=%d\n", i, T1[i]);
	}

	do {
		printf("Enter N2: ");
		scanf("%d", &N2);
	} while (N2<0 || N2>SIZE);

	for (i = 0; i < N2; i++)
	{
		printf("Enter T2[%d]: ", i);

	}

	}

	
	
	for(i=0;i<N1;i++)

			break;
	}
	
	if(found==1) // check reverse order
