In c plus plus you cannot assign integer value to enum?
That is correct - In c plus plus you cannot assign integer value to enum - You can only assign an enum value to an enum. Even though an enum looks like an integer, it is not. It is an enum, and C++ implements strict type checking to reduce the probability of bad programming practices. enum ColorCode {black, brown, red, orange, yellow, green, blue, violet, grey, white}; ColorCode myColorCode; myColorCode = yellow; Even though yellow has an integer value of 4, you cannot say myColorCode = 4.
When A B and C are counting numbers and both A and B are multiples of C what can you say about A plus B?
If A and B are multiples of C, then A + B is also a multiple of C: If A is a multiple of C then A = mC for some integer m If B is a multiple of C, then B = nC for some integer n → A + B = mC + nC = (m + n)C = kC where k = m + n and is an integer → A + B is a multiple of C
