A common trick to work around that anachronism, is to// define the following macro:// #define for if (0) ; else for#include <iostream>char const char_table[] =   "abcdefghijklmnopqrstuvwxyz0123456789-*&@. \\~";int main() {   // Do not include the terminating null of chartable!   // Decimal first:   for (int k = 0; k<sizeof(char_table)-1; ++k)      std::cout << char_table[k] << '\t'                << dec << int(char_table[k]) << std::endl;    // Or, since dec is the default:    for (int k = 0; k<sizeof(char_table)-1; ++k)       std::cout << char_table[k] << '\t'                 << int(char_table[k]) << std::endl;   // Hexadecimal:   for (int k = 0; k<sizeof(char_table); ++k)      std::cout << char_table[k] << '\t'                << hex << int(char_table[k]) << std::endl;   return 0;}
