Thread: A little question about formatted output

Just wondered if this will put the titles in tabular format:

printf("%13s%13s%13s\n", "Car", "Hours", "Charge");

if not, what's wrong with it?
thanks,

Why don't you tell us if it does what you want or not and if not what does it not do that you want it to. We arn't compilers for you personnel use.

Is this kind of what you are looking for?

Code:

#include <stdio.h>

int main()
{
	int hours[3];

	//////////
	// Get user input
	///////////
	for(int car = 0; car < 3; car++) 
	{
		printf("How many hours was the car[%d] parked for?: ", car);
		scanf("%d", &hours[car]);
	}

	/////////
	// Print out stats
	//////////
	printf("%-13s%-13s%-13s\n", "Car", "Hours", "Charge");
	for(car = 0; car < 3; car++)
	{
		if(hours[car] <= 3) 
			printf("%-13d%-13d%-13f\n", car, hours[car], 2.0);
		else if(hours[car] > 3) 
			printf("%-13d%-13d%-13f\n", car, hours[car], 2 + (hours[car] * .5));
		else if(hours[car] >= 24) 
			printf("%-13d%-13d%-13f\n", car, hours[car], 10);
		else printf("\n\n\twtf");
	}
	return 0;
}

The output:

Code:

How many hours was the car[0] parked for?: 20
How many hours was the car[1] parked for?: 5
How many hours was the car[2] parked for?: 2

Car          Hours        Charge
0            20           12.000000
1            5            4.500000
2            2            2.000000

Here's a nifty little format string (not the exploit...) reference: http://www.cplusplus.com/ref/cstdio/printf.html

Thank you very much tonto I'm sure this will help, I'll compare your code to mine and see if I can fix it.
The only difference is it shoud only output:
Car Hours Charge
0 20 12.000000
1 5 4.500000
2 2 2.000000

I'm also supposed to use a user defined function (gotta show we know how to use them)

i"ll let ya know if I get it.
Thanks again,
bryan

I don't see a difference between the output you expected and the one I posted. Except mine had questions. I mean, you do want the user to enter the number of hours and such right? I just copied the entire programs run history in the console to here, so the questions aren't technically part of the feedback of your program.

On another note, it is important to ask more specific questions than:

This makes the reader think that you made no attempt to try for yourself, in addition to the fact that it is extremely vague and doesn't make much sense. Anyways, uh, good luck on your assignment, and take into consideration what the others have said here. Make your questions clear, concise, thought through, and whatever else makes a good question.

I'm so close to being done with my code for this one but my function is only retuning 2.000. I really wrapped my brain around this one and can't seem to figure out why it won't work.

Any thoughts? I'm new to user defined functions (and I'm required to use one here)

Code:

#include <stdio.h>

float calculateCharges(float charge);

int hours;
float charge; 
int main()
{

   int hours[3];
 
	for(int car = 0; car < 3; car++) 
	{
		printf("How many hours was the car[%d] parked for?: ", car);
		scanf("%d", &hours[car]);
	}


	printf("%-13s%-13s%-13s\n", "Car", "Hours", "Charge");
	for(car = 0; car < 3; car++)
	{
		if(hours[car] <= 3) {
			charge = 2.0;
			printf("%-13d%-13d%-13f\n", car, hours[car], charge);
		}

		if(hours[car] > 3) {
		printf("%-13d%-13d%-13f\n", car, hours[car], calculateCharges(charge));
		}
		if(hours[car] >= 24) {
			printf("%-13d%-13d%-13f\n", car, hours[car], 10);
		}
		 printf("\n\n");
		
	}
	return 0;
}
float calculateCharges(float charge)
{
	
		charge = 2 + ((float)hours * 1 / 2);
		return charge;
