Ihave been trying to test my load function separately,since I have not implemented other functions,size,check,unload . I have got the following Clang error " expected identifier". I do not know how to eliminate this error.Any help in this regard will be appeciated. I have also another question. When we use a hash table, how do we ensure we check for collisions? Everytime that we calculate a new value using the hash function,do we check that value with all the earlier values calculated. I thought this would be very inefficient. Hence there must be a quicker way to detect collisions in the hash Table. uma1966
