Program crashes when calling check flag function on an unset bit: variable bit is used without being initialized Size should initially be equal to the number of bits requested by the user, and capacity should be equal to the maximum number of bits the data structure can hold without a resize; for example, with an initial size of 61, the structure would have a size of 61, 2 integers in the data array, and a capacity of 64. Currently the program allocates a single integer, regardless of flag position given
