Conversion of Char to Binary in C

Convert a String of Hex into ASCII in Java
Just use a for loop to go through each couple of characters in the string, convert them to a character and then whack the character on the end of a string builder: String hex = “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”; StringBuilder output = new StringBuilder(); for (int i = 0; i < hex.length(); i+=2) { String str = hex.substring(i, … Read more
