If statements

Chinpoki · 2024-02-01T00:54:49.330Z

Hey guys, sorry if you think this problem is too easy but i just can't find what's wrong with it. I am learning c# actually. In the solution, whenever i execute the program it jumps to the ELSE statement no matter what input i provide . If anyone could please help, THANK YOU !!

Are you using capital Y or N instead of lowercase ?

A

Austin9675•2/1/24, 1:04 AM

you gotta be typing something wrong because i recreated ur code and it works fine for me

C

ChinpokiOP•2/1/24, 1:17 AM

No i used lowercase even so it doesnt work

C

ChinpokiOP•2/1/24, 1:17 AM

It actually only executes the esle statement for some reason

C

ChinpokiOP•2/1/24, 1:18 AM

For example insert 10 it does 10 * 125 when actually it should be doing the first IF statement

C

ChinpokiOP•2/1/24, 1:19 AM

including the premium and discount

A

Austin9675•2/1/24, 1:19 AM

hold on i misread ill try it again

C

ChinpokiOP•2/1/24, 1:19 AM

ok

A

Austin9675•2/1/24, 1:22 AM

its still working fine for me , i have not ran into any issues, using 10 and hitting y prints the first statement for me

C

ChinpokiOP•2/1/24, 1:22 AM

wait rlly ?

C

ChinpokiOP•2/1/24, 1:22 AM

What is the answer when you do so

C

ChinpokiOP•2/1/24, 1:22 AM

when you hit 10 and "y:

A

Austin9675•2/1/24, 1:25 AM

1062.5
the problem is how you have ur code

A

Austin9675•2/1/24, 1:25 AM

this is how it works for me

int textbook;
char cover;
double rprice;
double fprice;

Console.WriteLine("Enter number of books");
textbook = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Do you want hardback? y/n");
cover = Convert.ToChar(Console.ReadLine());

rprice = textbook * 125;

if (cover == 'y' && textbook > 4)
{
double discount = 0.20; // 20% discount
double tax = 0.05; // 5% tax

fprice = rprice - (discount * rprice) + (tax * rprice);
Console.WriteLine(fprice);
}

C

ChinpokiOP•2/1/24, 1:27 AM

The syntax looks the same though , just you assigned variables for discount and tax

and yes variables is how i got the progam to work, i was running into the same issue

CChinpoki what is this

ChinpokiOP•2/1/24, 1:30 AM

You only have one if statement though and it will obviously only execute the said statement

M

mtreit•2/1/24, 1:32 AM

Start with that code. Does it work for you or not?

M

mtreit•2/1/24, 1:32 AM

If so, start building back to the full program.

M

mtreit•2/1/24, 1:32 AM

Go piece by piece to figure out what's going wrong.

M

mtreit•2/1/24, 1:33 AM

It's usually best to test your code a little at a time and make sure each part is already working before you move to the next piece.

C

ChinpokiOP•2/1/24, 1:34 AM

I did try it many times and got hopeless and came here

M

mtreit•2/1/24, 1:34 AM

Well, step back, take a deep breath and first try the code that @Austin9675 posted.

ok

mtreit•2/1/24, 1:35 AM

Also, step through the code line by line in a debugger or add print statements to print out the values of your variables to make sure you understand exactly what your code is doing.

trust me coding isnt easy it isnt really meant to be

Austin9675•2/1/24, 1:36 AM

theres plenty of times where i cant figure something out, thats why im in this discord

C

ChinpokiOP•2/1/24, 1:36 AM

Ok lemme compare your code and mine hopefully find whats wrong

C

ChinpokiOP•2/1/24, 1:37 AM

Ohh i get it

C

ChinpokiOP•2/1/24, 1:38 AM

You cant skip the if statements? thats why you printed the calculation in each statement ?

M

mtreit•2/1/24, 1:39 AM

Moving the print to the end (outside all of the if and else checks) should also be fine.

Austin9675•2/1/24, 1:42 AM

When you use 20 / 100 or 5 / 100, the result will be truncated to an integer in C# because both operands are integers.
you should use floating-point literals or explicitly cast one of the operands to a double
