%d, %s????

What do %d, %s and other things like that do, and what are they called?

well these were used in operations in C...you could still use it in C++, but why would you

%d is used for ints I believe it stands for "decimal" and %s is used for strings, er char arrays...

for example:

Code:

int x=3;
char *foo = "bar";
printf( " this is the number: %d and this is the string: %s", x, foo );
//prints out: this is the number: 3 and this is the string: bar

C style format flags used with I/O routines like printf() and scanf().

but how does it kno which number to use and which char array to use?

printf( " this is the number: %d and this is the string: %s", x, foo );

look at the code DeepFyre, x=3, and foo=bar;

Code:

printf( " this is the number: %d and this is the string: %s", x, foo );

It accepts an "unlimited" number of arguments, by order of where the % operators are used.

yea i know that axon, but what if there were more variables?

>>by order of where the % operators are used.
so would it use the first number/string it comes upon?

EDIT:: yes, that is why he said by order

So the first %d in your code will respond to the first argument after the string. And the second %whatever will respond to the second argumentand so on
