how can i save a value if i don't want to do as follows:
printf("Enter the hours parked: ");
scanf("%f",&a);
because i don't want the output to have the sentence "Enter the hours parked:"
the output required is as below(must be exactly the same):
cars hours charges
1 1.5 2.00
2 4.00 2.50
3 24 10.00
TOTAL 29.5 14.50
the charges value are determined by the hours...
and the user are only required to enter the hours...
please kindly assist...
thank you..
You can get the user to enter the number of hours parked on the command line, then parse the command line arguments.

what is parse line arguments??
the question is suppose to be answered by using function...
so, is parse the command line arguments meant for functions?
thanks..
I am talking about command line arguments.what is parse line arguments??
That's secondary to the problem. The problem is how you want the user to enter input.the question is suppose to be answered by using function...

yup..
i agree that it is the secondary to the question i asked..
and i browse through the link you have attached but i can't understand..
apparently my lecturer haven't taught me about that topic...
could you please generously elaborate more on how the user should input the data, please?
thanks in advance..
In that case, your lecturer probably would not want you to use command line arguments. You should either check with your lecturer, or simply do not use it.apparently my lecturer haven't taught me about that topic...
You could read the input from a file.could you please generously elaborate more on how the user should input the data, please?
Of course, you do not actually have to print "Enter the hours parked: ". You could just read the user input and assume that the user knows that it is for hours parked.
What exactly did your lecturer say, anyway?

the request by my lecturer is as postes in my other thread...
the title is assistance in function...
and i included my code in there...
please help me to have a look at it and i know that my code is terribly wrong as the output is not what i want...
thanks in advance again...
Your other thread does not state what the lecturer actually said, only your interpretation of the problem.
Did your lecturer specify what would be the format of the input?

my lecturer just said that the output must be the same as posted...
no adding.. no reducing...
the output should only be in this form (no extra sentences):
car Hours Charge
1 1.5 2.00
2 4.00 2.50
3 24.0 10.00
TOTAL
I see. Then just assume that the user knows what to input, and read input accordingly. Pretend that you printed "Enter the hours parked: ", but do not actually print it.

i'm finding trouble how to obtain the value for hour since i can't printf and ask the user to input it there..
please help..
thank you very much..
Precisely. If you do not print anything extra, the output will be the same as required.my lecturer just said that the output must be the same as posted...
Do not printf() anything other than the required output. Just start reading immediately. The user is assumed to know what to input.i'm finding trouble how to obtain the value for hour since i can't printf and ask the user to input it there..
This is an example:
Sure, it looks strange, but perhaps your lecturer will do I/O re-direction (if you do not know what that is, just ignore it for now).Code:#include <stdio.h> int main(void) { int x; scanf("%d", &x); printf("You entered %d\n", x); return 0; }

but i still encounter problem(s)...
are my code in the previous thread wrong?
ya.. i know it is wrong..
but i can't figure out where's those wrong that makes the output not what i want...
Yes. Don't you get warnings when compiling? Fix those warnings.are my code in the previous thread wrong?
Look up a C++ Reference and learn How To Ask Questions The Smart Way
but i really don't understand the warning:
possible use of 'p' before definition in function main ()..
no matter how i put it there's still warnings around..
is that warning mean that i should initialize it first inside the main..??
but i already did that...
yet it is wrong..
