I tried explaining what was going on with the "extra set of parens". A int(*)[5] incremented by one, dereference this new pointer to look at the first element of this imaginary array, then move back...
#include <iostream>
int
main (int argc, char * argv[])
{
int x[] = {1,2,3,4,5};
std::cout << *((*(&x+1))-1) << std::endl;
}
void func1 (int &a) {
func2 (a);
}
void func2 (int &a) {
a = 3;
}
pass the arguments to 'playerMove' as references aswell if you want to be able to change their values.
class A {
public:
A (int x) {};
};
class B {
public:
B (int x) : m_A (x) {}
private:
I'm guessing you having been copy+pasting a bit wrong since the if-statements on line #14, #16 and #18 are still "wrong"*
You should also go through the logic of your program to find some other...
for starters, use else if instead of just using if (icecream == ""), if (sauce == "") and if (sprinkles == "").
edit
When I look closer to your source I see that there are more places where you...

if you want the input to be stored inside a std::string, read my post above.
...
read the input as you normally would (into a std::string-instance), then use std::string::find_first_not_of, passing a string with all valid characters . If the function doesn't returns...
>Will increasing xincrease (ie, 'b') increase the probability of the statement being true?
No, decreasing it will increase the probability of the statement being true.
rand() % 1 == 0, true for...
I'm a slowpoke but:
the *this-pointer inside a class is good for many things, for example if you got a class-function where you have a parameter with the same name as a class-member, when you want...
Why don't you write a simple program to check just that?
if ((&(A[5]))-3) == (A+2)) {
printf ("same addr!\n");
} else {
printf ("doh!\n");
}
yes, delete[] should have been used. I was in a hurry catching my ride down to Gothenburg (Sweden) (and it was 3:41 am). no sleep for 38 hours + stress = bad combination
And since OP wanted to...
No, you will have to make char *route point to a location where you can write data read from stdin (std::cin)
char *p = new char[1024];
std::cin >> p;
std::cout << "input: " << p <<...
you can make your std::string return a valid 'char *' to itself by calling it's <string>.c_str();
std::string path ("./my_file.txt");
std::ifstream f (path.c_str(), std::ios::binary);
...
true, but as written earlier - I'm only writing examples. and this time it was to show that you cannot always trust std::map's default usage of std::less - even though it can be trusted when dealing...
<- slowpoke, read post above (edit)
It is easier to read the code if you do some consistent indentation:
do {
db.insertionSort(); // insertion-sort...
Since I hardcoded this small "application" to add my value to '_map', and since it was only a demonstration of using std::pair as a key in a std::map I didn't see any reason to check if it was really...
Something like this?
#include <iostream>
#include <utility>
#include <string>
#include <map>
typedef std::pair<char,char> p_key;
You should close open file-descriptors that are lying around.
If this is important or not is up to you, but if your process has a lot resources open at the same time and the OS the process is...
Pretty much nothing. As long as you check if the return-values from fork and exec~ functions are satisfying you will be alright.
(For example, don't forget to exit the child if exec~ was...
An easy approach would be to alter your recursivefunction to make it work in a different way. You could, for example, do something similar to the code below. Since the function is not recursive the...
I'm sorry but I haven't read any C-book in my life, so I got nothing to recommend. For me trial and error has worked fine, and I also think that it is the best way of learning.I'm not saying that...
If I understand you correctly you would like to do something like this(?):
#include <stdio.h>
#include <assert.h>
int
main (int argc, char **argv)
{
unsigned short op_code, tmp;
There are many ways of doing this. if you are looking at a school-assignment your teacher might want you to read on about loops and such. Just picture how you would do this math in your head, and...
if you are thinking of the C++ STL type "std::map" you are in the wrong forumsection, otherwise: read on.
