c++ cli - Conversion from String to Char in visual c++ -


i taking input user in visual c++ through following code

console::writeline("select cache size.\n a. 1 kb \n b. 2 kb \n c. 4 kb \n d. 8 kb\n");     string^ cache_sizeoption = console::readline();     char wh= char(cache_sizeoption);      switch(wh)     {case 'a':     break;      case 'b':     break;      case 'c':      break;      case 'd':     break;     }

in conversion string char giving errors..

 error c2440: '<function-style-cast>' : cannot convert 'system::string ^' 'wchar_t'

it's unrealistic expect able convert string character. string can contain 0, 1 or more characters. character want?

if want first character, use cache_sizeoption[0], after having checked string not empty.

in case want add check string's length 1 because otherwise means user's input invalid. check cache_sizeoption->length.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
