Hex and Decimal

Write a function void printHexDec(ostream& out, int n) that writes n in decimal, then a space, an equals sign, a space and 0x, then n again in lowercase hexadecimal (no padding), then a newline — for 255 the line is 255 = 0xff, for 0 it is 0 = 0x0. Print the 0x prefix as a plain string, switch the stream to hex for the second number, and switch it back with dec before returning.

The test prints another integer (100) through the same stream right after the call (see Expected Output).

Do NOT write a main function.

Expected Output:

255 = 0xff↵
100↵
4096 = 0x1000↵
0 = 0x0↵
42↵

= newline. The output ends with a newline — print one after the last line.
