The 's' replaces one Room match at any given time however the 's+' replaces The complete space sequence at the same time with the second parameter.

In this case, it can make no difference, since you are replacing all the things using an vacant string (Whilst It might be superior to use s+ from an efficiency perspective). For those who were replacing using a non-empty string, the two would behave in different ways. Share Make improvements to this answer Adhere to

In a few code that I've to keep up, I've witnessed a format specifier %*s . Can any one explain to me what This can be and why it is applied?

Making use of %s in scanf without the need of an explcit discipline width opens the same buffer overflow exploit that gets did; particularly, if there are actually a lot more figures during the enter stream compared to focus on buffer is sized to carry, scanf will Fortunately generate These excess people to memory outside the buffer, probably clobbering anything vital. Unfortunately, in contrast to in printf, you can't supply the field with as a operate time argument:

This is certainly relatively typical mistake-checking code for the Python script that accepts command-line arguments.

Utilizing scanf with the %s conversion specifier will prevent scanning at the 1st whitespace character; as an example, In case your enter stream seems like

The width is not really specified in the structure string, but as yet another integer worth argument previous the argument that has to be formatted.

char character; // just a char 1 letter/from your ascii map character = 'a'; // assign 'a' to character

How do I stay away from Doing work extra time on account of youngsters's insufficient organizing without having harming them as well poorly?

Each of the illustrations specified beneath use arrays which hasn't been taught nevertheless, so I'm assuming I can not use %s still possibly.

The width is not laid out in the format string, but as an additional integer value argument previous the argument that must be formatted.

If the value to generally be output is a lot less than 4 character positions large, the value is true justified in the sector by default.

If the worth is greater than four character positions broad, the sector width expands to support the appropriate amount of characters.

So the main if assertion interprets to: when you have not here passed me an argument, I'm going to let you know how you ought to pass me an argument in the future, e.g. you will see this on-monitor:
