Char array into single char C++

Question

Let’s say we have an array:

unsigned char array[]={‘1’, ’5’, ‘3’}

This elements are acording to ASCII 0x31, 0x35, 0x33
And i need to make a single number out of those elements 0x313533
Does anyone had any idea how can I add them like that???

Answer 1

The shortest approach I can think of is to use a stringstream, since it can automatically assume a hexadecimal base for its operations. Here is an example:

Otherwise, you would probably have to do the conversion yourself, i.e. from char to decimal to hex, followed by a concatenation of the values.
