How many bits is a char in c++
Webchar The char type takes 1 byte of memory (8 bits) and allows expressing in the binary notation 2^8=256 values. The char type can contain both positive and negative values. … WebIt is not that it is getting 12 bytes allocated, but instead that there is a 4 byte hole being skipped between the 8-byte long and the prior 4-byte sized variable. This 4 byte area is skipped over, because using it for the long variable …
