No, they are variadic.
well major difference between scanf and printf is that scanf is an input statment and printf is an output stament scanf is used to take data in from the user and printf is used to display the result on the screen Regards
Yes: double d; printf ("scanf's just returned %d\n", scanf ("%lf", &d));
int printf (const char *fmt, ...)orint scanf (const char *fmt, ...)
Printf prints something to the standard output stream, and scanf inputs something from the standard input stream.
Printf returned no. of character receive . scanf return no of variable to be inputed according to format specifier . eg: i=printf("thisisc") printf("%d",i); //i=7 j=scanf("dd",&a,&b,&c,&d); printf("%d",j); IT IS MOST APPROPRIATE ANSWER FOR THIS Q .......... PLZ DO Practically............

we write printf() b/c it printf or show us the value contained in a value on the screen after pressing ctrl+f9.
