Anyone see why this doesn't work?

I'm new to C programming, but not to programming. Can anyone see why this code isn't working? It seems to be the simplest program in the world, but it always returns a product of 0.00000. If anyone can spot what I'm doing wrong, please reply.

Thank you.

Code:

#include <stdio.h>

float x,y, prod;

float fmu(float a, float b);

main()
{
	puts("Enter two floats to multiply");
	scanf("%f %f", &x,&y);

	prod=fmu(x,y);

	prfloatf("\nThe following is the product...%f", &prod);

	puts("\n\n\nEnter a single digit to exit");
	scanf("%d", &x);

	return 0;
}


float fmu(float a, float b)
{
	return (a*b);
}

What is prfloatf? And if it's anything like printf, then you should not be using the address-of operator (&) in that particular function call.

Removing the ampersand should do.
lol .I think the OP should have used the search and replace option to replace int with float.

Haha. Now that you mention it, I think that's exactly what he did.

Your main should be defined as int main(void), not main(). Also, to the OP, get away from using global variables. Define the variables in main(), and if you have to, pass the variables from your main to your function fmu().

Simple typos. I did a replace from int to float and the ampersand was incorrect.

Guess I'll get new glasses!

Thanks all.
