# What is the use of sprintf() function?

**The sprintf() function writes a formatted string to a variable.**

The arg1, arg2, ++ parameters will be inserted at percent (%) signs in the main string. This function works "step-by-step". At the first % sign, arg1 is inserted, at the second % sign, arg2 is inserted, etc.\
