Buffer-overflow
Not what you're looking for?
Buffer-overflow is a common computer security concern. Write a simple program, in C, C++, and Java, to declare a simple one dimensional array and then attempt to access an array element that is not within its bounds. For example, what happens if I declare an array to be in studentNums[10] and then attempt to access studentNums[11], studentNums[12], or ..., studentNums[100] ?

In C/C++ the system does allow accessing an array element that is not within its bounds.
For instance this C/C++ code:
#include <stdio.h>
#include <memory.h>
int main()
{
int studentNums[10] ;
memset ((void *)studentNums, 0x00, sizeof (studentNums)) ;
printf ("studentNums[9] = %dn", studentNums[9] ) ;
printf ("studentNums[10] = %dn", studentNums[10] ) ;
printf ("studentNums[11] = %dn", studentNums[11] ) ;
studentNums[11] = 11 ;
printf ("studentNums[11] = %dn", studentNums[11] ) ;
return 0;
}
outputs:
studentNums[9] = ...
