hi i am trying to passing arthematic expressions through command line arguments but i only get result of addition and multiplication cant get result of
subtraction and division:
//c:\jdk1.6.0\bin \javac mentalmath
//compilation is successful
c:\jdk1.6.0\bin \java mentalmath 12 6
**result** 72 18 // only give result of multiplication and addition of above numbers. but not give result of subtraction or divsion.
Code:
class mentalmath
{
public static void main(String args[])
{
int multiply= 1;
int sum=0;
// int minus=0;
for(int i=1;i<=args.len gth;i++)
{
multiply=multip ly*Integer.pars eInt(args[i]);
sum=sum+Integer .parseInt(args[i]);
// minus=minus-Integer.parseIn t(args[i]);
}
//System.out.prin tln("the minus is"+minus);
System.out.prin tln("The product is " + multiply);
System.out.prin tln("the sum is"+sum);
}
}

2.) Where in your code did you instruct the program to subtract or divide?

You should start your loop at i= 0, not i= 1 and you should stop one loop pass
earlier; like this: -
for (int i= 0; i < args.length; i++) ...

Hi,
if you want to get the result for minus, u need to use below code:
minus=Integer.p arseInt(args[0])-Integer.parseIn t(args[1]);
For the division also u need to use as above.
cheers,
Sateesh

OK, I want to scan a file for lines matching a certain regexp. I'd
like to use an assignment expression, like
for line in file:
if (g := re.match(pat, line)):
croggle(g.group(1))
Since there are no assignment expressions in Python, I have to use a
temp var. That's a little more messy, but bearable:

Bear with me, as I am not a "professional" programmer, but I was
working on part of program that reads parts of four text files into

top down, moving the bottom items back to the new re-allocated

Then when I've read all four files, I sort the top and bottom items

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
