I always though that if I declare these three variables that they will all have the value 0

int column, row, index = 0;

Possible approaches:

• Initialize all local variables with zero.
• Have an array, memset or {0} the array.
• Make it global or static.
• Put them in struct, and memset or have a constructor that would initialize them to zero.
