}

When program is running, after I input key number I provide, it doesnt display only 5 positions but rather displays an infinite loop of some sort PASSED the array. HELP!

for(int k = i; k < (k+2); k++)

Your problem is here. The value k will always be less than k + 2.

Try
for (int k = i + 1; k < (i + 3); k++)
