//Fuel SCAN PROGRAM

void main(void)

{

float distance, gallons, MPG;

 

printf("Enter distance followed by space than gallons used. \n");

scanf("%f %f", &distance, &gallons);

MPG = "%f / %f", &distance, &gallons;

printf("Fuel Effiency is: %f\n", MPG);

}

My teacher told us to make a program that calculates the fuel effeicny in Gallons and Liters and I know this is wrong lol but I can't get this to work and I do not have the liters area yet any help anybody?

MPG = "%f / %f", &distance, &gallons;

 

The MPG = garbage line is a bit strange.

 

Something along a formula from your math lessons might be what you are looking for.

 

MPG = distance / gallons;

 

But the rest of the program looks OK to me.

MPG = "%f / %f", &distance, &gallons;

 

Like Karri said, you have tried to use the syntax of the scanf function to do math.

 

C = A / B; // division

C = A % B; // mod

C = A * B; // multiplication

C = A + B; // addition

C = A - B; // subtraction

 

that's the basic math syntax in C... you could probably ask your teacher for help, that's what he's there for!

 

Oh, I've always considered it good programming style to put in a "return;" even when the function doesn't return anything. Is that not taught today, or am I just plain wrong on that?

I don't know I would consider that good programming style. That is a redundant statement, which doesn't aide readability IMO, so I would leave it out.
