It points to a memory location and so it is not possible for temp to have a value like: "0472AB12CBAC" It can point to memory location where information like that is stored, but the actual variable temp itself is just a memory location. Converts base64 string into image. [byte[]]@(18,52)). For example, a 30 gigabyte drive is usually 30,000,000,000 bytes (decimal) not the 32,212,254,720 binary bytes you would expect. And they assume the input you wish to convert to binary is an integer — this character parsing chokes on types whose string representation includes a decimal point (float, double, decimal). It compares the value of the string object (or a substring) to the sequence of characters specified by its arguments. If you simply cast input to char* and output it, then the bytes will be interpreted as if the file already contained ASCII characters. You simply convert each byte to hexadecimal, ideally to a preallocated buffer. There were other ways of representing strings, like setting the high bit of the last character to mark the end (saves a byte per string, but halves the character set size), or prepending the length (making it unnecessary to scan through the string to find the end, but capping string size at 255 bytes), or even storing tuples of lengths and.
