Description

   The sprintf function places output followed by the null character
   (\0) in consecutive bytes starting at *str. The user must ensure
   that enough space is available.

   Consider the following example of a conversion specification:

   #include <stdio.h>

   main()
   {
      int  temp = 4, temp2 = 17;
      char s[80];

      sprintf(s, "The answers are %d, and %d.", temp, temp2);
   }

   In this example, character string s has the following contents:

   The answers are 4, and 17.
