tags Programming Computer Science For understanding how pointers work, consider the following simplified memory layout. the memory address starts in 0x1 and goes up to address 0xA. The value row holds the current data stored in that memory cell. Address 0x1 holds a pointer to address 0x6, which in turn 0x6 holds the value s. Address 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xA Value 0x6 s e d s \0 Variable name hostname hostname hostname + 1 hostname + 2 hostname + 3 hostname +4 . ...
