I wrote a code for entering element and displaying the array at the same time. The code works but since char A[4] is static memory why does not it terminate/throw error after entering more than four elements? Code:
#include <iostream>
using namespace std;
void display(char arr[],int n)
{
for(int i=0; i<n; i++)
cout<<arr[i]<<" ";
return;
}
int main()
{
char A[4];
int i=0;
char c;
for(;;)
{
cout<<"Enter an element (enter p to end): ";
cin>>c;
if(c=='p')
break;
A[i]=c;
i++;
display(A,i);
system("clear");
}
return 0;
}
The code has a bug. It will not work correctly until you fix the bug. It really is that simple.
