tough question
Write a program that uses a user defined function called 'truncate()' which separates the integer and the decimal part from a float value.
The prototype for this function is as follows :
void truncate (float);
The function accepts a float value from main () and truncates the decimal part of the variable
plz help
Read this, in particular, the homework section.
When all else fails, read the instructions.
If you're posting code, use code tags: [code] /* insert code here */ [/code]
Please don't just post your homework questions, at least try to solve them and be able to prove it or you won't get help here. I will offer suggestions to get you started though, try printing the float value cast to an int and see what you get.

My best code is written with the delete key.
i tried. it was wrong, which is why i am here. so what, the rules are i cant be helped?
my output:
Enter a decimal point number : 12.60
After truncating the variable, the values are : 12.00 and 0.75
Do you want to run the operation again [Y/N]? n

wrong.
>i tried. it was wrong, which is why i am here.
Then you'll need to describe what the output should look like in all cases because this works just peachy for me and I can't see you needing to handle values that would overflow an int for homework:
>so what, the rules are i cant be helped?Code:void truncate ( float val ) { std::cout<< (int)val <<std::endl; }
No, the rules are that you will not be helped if you don't bother trying to solve the problem on your own. We assume this to be the case if you do nothing but post the problem you were given and not any solutions you have tried that didn't work.
-Prelude

check it out.
//
//
//
#include <iostream.h>
void truncate (float);
void main ()
{
int a;
int b;
float c;
cout<<"enter your number"<<endl;
cin>>c;
cout<<"values are "<<a<<"and"<<b<<"<<endl;
}
void truncate (float)
{
int a= float c;
int b=(c-a);
return a,b;
}
Well, for one thing, where in main do you call truncate()?
For another, how are you returning two values?
For that matter, why does truncate() have a data type but not a data variable? etc...
I'm not trying to pick on you, but you need to spend some time learning about functions and passing arguments; forget about actually splitting the integer and decimal parts for now.
