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

[artistunknown]

I can't figure this out
this is the 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:

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

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

#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

[Subsonics]

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.

[Adak]

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.

[kira_coder]

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

[artistunknown]

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

[artistunknown]

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
