// sprintf() works just like printf() but instead of printing to standard out
// it prints to the given string.
//    see printf.cpp for an example of printf

// sprintf can be uses it to convert numbers to string.

// int sprintf(char *str, const char *format, ...);
//  str is a buffer into which the generated string is placed
//  format is the string that contains the format
//  for example:
//       "My name is %s.  I am %d years old"
//       the %s will be replaced with the first argument
//       the %d will be replaced with the second argument
