Need a little help!!
Hi, i'm doing my assignment and i dont know this particular coding.
Well to sum up my question....
i need to know what is the code to find the balance of a number after it has been deducted to 10 percent.(this is only a small part from the whole assignment)
Anybody would like to tell me?
I need a full code if you don't mind.
Thanks.
oh and i need it like ASAP!!

You need to read our homework policy ASAP!!

I have read it and my question is not against the policy.
My question was about one particular code. And the code i'm asking is not for the entire assignment. it's just apart of it. I have done the other code(assignment's) except for that . So that's why i'm asking.
The code part is irrelevant, as it almost exactly equivalent to the math of it.
How would you remove 10 % from a number?
I note that you wrote: "I need a full code if you don't mind."I have read it and my question is not against the policy.
Anyway... if I am reading it correctly, it is so trivial that the bulk of the code is a one liner. If you have a number x, what is ten percent of x, expressed as a fraction? What about expressing it in decimal?

ok let say a person's salary is $2345.
my program identifies whether the salary needs to be deducted 10 percent or not.
if it needs to be deducted,I just need to know the salary balance.
that's all.
I have tried to put this code into my coding but it wont show up anything on the black screen after the data has been entered.
Code:total_salary=salary-salary*0.10
Ah, now we're seeing something. Okay, that looks like it will work. Perhaps you carelessly forgot to print total_salary, hence "it wont show up anything"? It would be good to provide the smallest and simplest (compilable) program that demonstrates the problem.

Sorry, can't help but post my one-liner:
Code:#include <stdio.h> #include <stdlib.h> int main() { char buf[20]; int n; printf("%d\n",(n = strtol(fgets(buf, sizeof(buf), stdin)?buf:"0", 0, 10))?n -= n / 10:0); return 0;}
This is a piece of code to subtract 10% of a number, not the full specs of your code. [And I would suggest that you DON'T use this code as part of your homework - it is not for homework level use [in fact, I wouldn't suggest using this sort of thing anywhere, except when the goal is to make one-liner code].

how should i do that?
i'm kind of new to C.
how do i print the total_salary
You have probably been taught how to use printf(), methinks. Use that.i'm kind of new to C.
how do i print the total_salary

ok, take a look at this....
is that correct? or do i need to put another printf?Code:total_salary=salary-salary*0.10; printf("your new salary balance is%f",salary);
printf seems about right, but perhaps you should consider WHAT you are printing in that printf.

err come again?
You are printing salary instead of total_salary.

it would be helpful if you show me the right printf code instead of making me confuse, don't you think?
