"It occurs in C as well so it's moot?" Isn't C++ is supposed to be an improvement over C? Surely there was a point to duplicating the C library functionality beyond keeping the status quo. I'm sure...
Sure, but it works pretty sloppily.
Try getting a line of input from cin. As we all know from C, scanf() is error-prone and we should be getting whole lines with fgets() and parsing that. So...
In C, ^ is bitwise XOR. You indeed need pow().
Furthermore, you aren't faithfully representing the summation; there are two errors. Try using a debugger to step through each line while watching...
Indeed. I have to second this notion.[/QUOTE]
I'd want to use it because iostream provides no genuine advantages over stdio, and several disadvantages.
Because that's just the way the language is designed.
C can have arrays like that, mind you.
We actually have a board for game programming.
I didn't read the code, but the smart-alecky summary would pretty much go like:
"Singleton Considered Harmful etc. etc.".
"Premature...
In this instance it would be vastly more readable to say return s != 1000;.
When you do the a-b, a is promoted to unsigned int, and so the expression result of -1 overflows to INT_MAX. Your platform has 32-bit ints, so this is 4,294,967,296. Assigned to a float, this...
And nothing of value was lost.
There's actually one for Windows: Visual Prolog.
And of course you can always fall back on Vim and Emacs plugins.
Find-String(T,P)
1 n ← length(T)
2 m ← length(P)
3 for s ← 0 to n - m
4 do if P(1 .. m) = T(s + 1 .. s + m)
5 then print “Substring found with shift” s
This pseudocode which I...
You can use strtok() to chop up the data, especially if your delimiters are no more complicated that a single comma.
If your C library is POSIX, you can use regex.h functions to parse it (but then...
You are assigning 'false' to 'search' in the while loop, not testing for equality.
In the future, turn up compiler warnings.
Some style notes:
Pupils and students are the same thing.
It's rather redundant to qualify a drop-down menu with "choose only one of the following".
"Qt" is a GUI toolkit made by Nokia. "QT"...
The straight answer is no, he means upgrade his hardware to PCIe or something.
It is where I'm sitting, at least:
$ c++ try.cc
try.cc: In function `int main()':
try.cc:9: error: invalid conversion from `int' to `main()::enum_t'
It's not an error in C. Maybe that's...
Because he doesn't want an enum, which restrict what you can assign to a variable to a number of identifiers, but something that can be assigned to at will, just not anything other that 0 to 4....
Your development suite doesn't support ISO standardized functions. So god only knows what else it's deficient in.
Probably a good idea to get a better development environment.
The implication of using fflush() on the stdin stream.
There's PyQt and a fine book on it.
--------------------------------
lulz.
Yes.
The latter is a C++ header file for accessing the functions in the mathematics library.
The former does not exist.
For what it's worth, it is in BSD and OS X.
And at any rate, strtod is the better function.
(Also, gets is still supported by the C standards, so that's really a suboptimal argument to make.)
You need to #include <stdlib.h>. And #include <stdio.h> while you're at it. (Why you need to be told this, I don't know...)
And also, atof is deprecated in favor of strtod. Replace with...
