Thread: Unfamiliar Function Syntax

I was recently reading a C tutorial and came across an unfamiliar way of making a function.
I was hoping someone could clear this up for me ... the code is below - im talking about the line after

"void swap(pnta, pntb)" where the line "float *pnta, *pntb;" appears ... I was always under the impression that directly after the function header came the blockquote "{"



Thanks in advance - /\/\artin

Code:

#include <stdio.h>

void swap();

int main(){

float a,b;

printf("Enter two numbers: ");
scanf("%f %f", &a, &b);
if (a<b)
swap(&a,&b);
printf("The required order is: %5.2f %5.2f\n",a,b);

return 0;
}


void swap(pnta, pntb)
float *pnta, *pntb;
{

float temp;
temp = *pnta;
*pnta = *pntb;
*pntb = temp;

}

Ok then I have a question - by K&R C, do you mean 1st or second edition of that book? Just curious, because even though the second edtion of K&R has the big red stamp 'ANSI' it is not exactly ANSI C anymore.

Thanks a lot for the prompt replies ... with your help I now realise that the it was older notation and I had only ever seen the newer ANSI way of doing it.

Thanks again for your help
