I'm just reading some code and I came across:
form method='post'
input type='hidden' name='input' value='%s'
What does the %s mean? I tried googling but I can't get an answer for this one.
%s most likely means a string. Sort of like a placeholder or variable.
In some languages you can write something like:
string name = "Joe";
printf("Hi %s", name);
Which would print out: "Hi Joe".
%s is used in a programming technique called 'variable interpolation'.
it will be replaced by a string somewhere later in the program
