Printf may be the second function that many programmers encounter when learning C language (I guess the first function is main). It is naturally an old friend. However, do you know much about this old friend? Do you know more about sprintf? When

Sprintf and printf, sprintfprintf       Sprintf has almost the same usage as printf, but the printing destination is different. The former is printed to the string, and the latter is directly output on the command line. This also
