What is the purpose of the sprintf function in C langua…

The sprintf function in the C language is a string formatting function that is used to write formatted data into a string. Its prototype is as follows:

int sprintf(char *str, const char *format, ...)

In this case, str is the buffer where the formatted string is stored, format is the format string, and the following parameters are the data to be formatted. The sprintf function formats data as strings based on the format specifiers in format and writes the results to str. It is similar to the printf function, with the key difference being that printf outputs results to the standard output stream (console) while sprintf outputs results to a string buffer. Therefore, sprintf is often used to store formatted data in a string for further processing or output.
