Syntax
printf(ControlString, arg1, ..., argn);
Everything within the ControlString is printed verbatim except %d’s
which are replaced by the argument values from the list.
Code example
int n = 1, m = 7;
printf("n = %d\nm = %d\n", n, m);
The output is:
n = 1
m = 7
%d is the conversion character.
\n is a special character.
See next section for a list of conversion characters.
