I only took this code from Thinking in C++ Vol-1 and it did not
compile because of this error. I noticed this line "system(char(26))"
in more than one code in the few 3 chapters of the book. and since it
is a book with some good reputation, I did not think it would be
incorrect. but it looks I have to do some homework.
Are you sure about that? I'm looking at the PDF version of the book
right now, and can't find that text anywhere. In fact, the only
reference to the system() function that I can find in any sample code is
on page 108:
//: C02:CallHello.cpp
// Call another program
#include <cstdlib> // Declare "system()"
using namespace std;
int main() {
system("Hello");
} ///:~
a while back I downloaded the book, I have now a directory with the
source codes, in the files for chapter 3, I could find these 2 programs.
