bool terminate)

Example Code

#include <iostream.h>
#include "CStringFormatter.h"

int main(int argc, char** argv) {
  //
  // Declare some local variables to demonstrate the data
  // types supported by CStringFormatter.
  //
  const char* s = "Hello World";
  bool b = true;
  int i = 1234;
  unsigned int ui = 32767;
  double d = 1.2345;

  //
  // Declare a formatter for a character buffer.
  //
  char buffer[128];
  CStringFormatter cstf(buffer, sizeof(buffer), true);

  //
  // The format string prints a boolean, an integer, two
  // unsigned integers, a floating point value, and a string.
  //
  const char* format = "bool    b = %b;\n"
                       "int     i = %d;\n"
                       "uint   ui = %u;\n"
                       "uint   ui = %x;\n"
                       "double  d = %f;\n"
                       "char*   s = %s;\n";

  //
  // Each of the variables b, i, ui, d, and s will be
  // converted to a Variant and passed to print.
  //
  cstf.print(format, b, i, ui, ui, d, s);
  cout << "result: " << buffer;
  return 0;
