Data entry options for an array using goto statement

 Data entry options for an array using goto statement:

//Multiple Input and output options for an array

#include<iostream>

using namespace std;

void main()

{

int arr[5];

int option,i;

int counter=0;

xyz:

cout<<"press 1, input"<<endl;

cout<<"press 2, output"<<endl;

cout<<"press 3, reverse"<<endl;

cout<<"press 4, to multiply data by 3"<<endl;

cout<<"press 5, addition"<<endl;

cin>>option;

if(option==1)

//input

{

cout<<"Enter the values of array"<<endl;

for(i=0;i<5;i++)

{

cin>>arr[i];

}

counter=counter+1;

}

else if(option==2)

{

if(counter==0)

{

cout<<"Firstly enter the array data"<<endl;

goto xyz;

}

   //output

for(i=0;i<5;i++)
