printf() is a function that prints formatted text to the console. It works like
printf("Hello World for the %d time",5);
%d will be replaced with "5" and the string will be printed to stdout.
for strings try %s and for floats %f

int printf(const char *format[, argument, ...]);

It's a function, rather special as it accepts a variable number of arguments, the only required parameter is the format string. This format stringr contains information about the optional arguments. Some examples:

printf("Hello World"); // no extra args, just a plain string

char* hello = "Hello World";
printf("%s", hello);

Now the fomat string contains a format specifyer, %s, which tells the function there is a string as extra argument. You can also mix:

char* world ="World";
printf("Hello %s", world);

There are many, many specifyers and format options, you should check your compilers documentation.
