I came across this C program in a blog post:
main()
{
int n;
n = 151;
f(n);
}
f(x)
int x;
{
printf("%d.\n", x);
}
The post doesn't explain it. Can anybody explain what this weird function definition means?
This is the K&R style of C code, it's still valid C syntax, but I suggest you not using it in new-written code.
f(x)
int x;
is equivalent to ANSI C:
void f(int x)
K&R C is the C language described in the first edition of the book C programming language by Brian Kernighan and Dennis Ritchie, and named after the two authors. The second edition of the book updated to use ANSI C.
