don't understand why this code doesn't work properly

I can't figure this out
this is the code

Code:

#include <stdio.h>

float Total_Revenue(float,float);

int main(void)
{
    float price = 0.00;
    float quantity = 0.00;
    float revenue;



    printf("Enter price:  ");
    scanf("%.2f" , price); 
    printf("\nEnter quantity:  ");
    scanf("%.0f", quantity);

    revenue = Total_Revenue(price,quantity);

    printf("The total revenue is %.2f" , revenue);

    return 0;
}

float Total_Revenue(float x, float y)
{
    float price;
    float quantity;

    return  price * quantity;
}

Here's the output


------------------------------------------------------------------------------------------------------------
Enter price: 5.00

Enter quantity: The total revenue is 0.00Press any key to continue...

------------------------------------------------------------------------------------------------------------
why won't it let me enter the quantity

You want to put the value into the address of (&) the variable, eg:

Code:

scanf("%.2f" , &price);

I tried this but it still gives me the same output I changed the code got rid of the function

Code:

#include <stdio.h>

int main(void)
{
	float price;
	float quantity;
	float revenue;



	printf("Enter price:  ");
	scanf("%.2f" , &price); 
	printf("\nEnter quantity:  ");
	scanf("%.0f", &quantity);

	revenue = price * quantity;

	printf("The total revenue is %.2f" , revenue);

	return 0;
}

You need to assign values to your variables in your revenue function.

Or, just return x*y directly.

I got rid of the function why won't this simple code work that I posted above

Take in all decimal points in your scanf call and you should be fine as far as I can tell. Then restrict it with printf like you do already.

Also if quantity should have zero decimals it might make sense to use an int there instead.

Because you are using printf() format specifiers, in scanf().

Remove the .2 and .0 in your two scanf()'s calls, and all will be fine.

remember those variables are local to your function so if u want you can either return them or put the variable in a ptr and use them later

Adak your a genius it worked thanks man

hey thanks everybody I learned something new that I didn't realize before or forgot

Subsonics you were right I just didn't think I could mix a int with a float but I guess you can

I should already know this stuff but I must of forgot about it
thanks for helping me understand it better now
