In certain code that I have to take care of, I have noticed a structure specifier %*s . Can any person tell me what this is and why it can be applied?

five @powersource97, %.*s suggests you happen to be reading through the precision value from an argument, and precision is the utmost quantity of characters to become printed, and %*s you are looking at the width worth from an argument, which happens to be the bare minimum number os figures to be printed.
