c C++ convert hex to ascii
// Presented with hex such as 0x12345abc perhaps there is a spot in there
// which represents an ascii char - such as 53 would be 'S'
// Common when dealing with hardware-related data structures and wire
// protocols
produces this output:
S
// which represents an ascii char - such as 53 would be 'S'

// protocols
#include <stdio.h> #include <stdlib.h> /* * To convert 53 to the character 'S': * char returnVal = hexToString('5', '3'); */ char hexToAscii(char first, char second) { char hex[5], *stop; hex[0] = '0'; hex[1] = 'x'; hex[2] = first; hex[3] = second; hex[4] = 0; return strtol(hex, &stop, 16); } int main(int argc, char* argv[]) { printf("%c\n", hexToAscii('5', '3')); }
produces this output:
S
