I have program. I need programing one game.
char girl;
char computer;
cout << "Girl choose one of symbol x or o";
so girl choose x.
problem : i need random symbol genetation. so if random symbol are x, than girl start play. if random symbol ar o, than computer start game. who to do this?
I am making a random number generator. I have fixed all issues except for one. I am supposed to ask the user for how many digits the user wants the numbers to have. How many numbers does the user want. Then randomly generate numbers according to what the user entered. So if the user said 2 digits and wanted 4 numbers then it would output 4 random numbers in the range of 10 to 99.
My notes from class show this working correctly. And it does work correctly. But I don't understand the math here or how the modulus effects it. I was able to get 1 and 2 digits to work but once I get to 5 it doesn't generate numbers correctly. it will only generate number s
Code: int min =1;
int max = 9;int number1 = rand();
cout << number1 % max + min << " "; h
Here is the 3 digit code I have. I also need to figure out how to make it unique so no number generates more then once. I think the issue may be that the numbers are not unique and it is generating the same number and that is somehow effecting the numbers it is outputting. It is either that or my math is wrong.
Code:
if (intLength == 5) {
for (int i = 0; i<intQuantity; i++) {
[Code]....
I've researched this quite a bit and the overwhelming answer I've been seeing for a loop generating the same pseudo-random number is that you're seeing the random number generator inside the loop, but that is not the case with me . . . At least not that I can see.
Basically, as I mentioned, I have a loop "birthing" new bunnies in a loop. And all the new bunnies are being created with the same name and other details.
Here is the code:
void BunnyGraduation::breed() {
for (unsigned int male = 0; male < colony.size(); male++) {
if (colony.at(male).getSex() == Bunny::Sex::MALE && colony.at(male).getRadioactiveMutantVampireBunny() != true && colony.at(male).getAge() >= AGEOFCONSENT) {
for (unsigned int female = 0; female < colony.size(); female++) {
[Code] ....
srand(time(0)); is seeded ONCE in the constructor of the bunny object itself. . . Now, come to think of it, the constructor is called every time an object is created . . . And the constructor contains the srand() . . . and the constructor is being called in a loop. . . So therefore, yes, the srand() is being called inside the loop.
I've attached a pic of the program im trying to make, i'll explain in a few steps what it's supposed to do and what my problem is:
-User types in the amount of each material used.
-User click's the "Add" button, to add the materials to the bill.
-The bill is supposed to be shown like this:
material1 3x 1340
material2 2x 930
material3 7x 240
material4 1 840
Total 3350
-My problem is that i have like 100 different Materials, and how i should make the program only write the Materials used on the bill, instead of writing all the materials Down, even those which havent been used.
-every material has their own double variable, and a another double variable for the total Price of used material.
-right now it Works as shown on the Picture, i can add amount of each material, and calculate the total Price, and clear all the textboxes.
So I am writing a map generation algorithm (with SFML), and it seems the problem is in here:

But when I run it I get: Unhandled exception at 0x69791f34 in sfmlproject.exe: 0xC0000005: Access violation reading location 0x001b5000.

I'm doing a homework assignment where I have to calculate monthly interest from a starting balance. I've pulled several sections of the code from various parts of the book. So my problem may be that I'm not combining them correctly.
I'm getting the following error:

The ios flags are new to me and that may be part of the problem. As soon as I can get a working program, I'm going to make the starting balance and interest rate user inputs. But I get seem to get past this error.

this is a win32 console application, like the books says, the book i am working from that is.
I'm building a cross-platform library which links to some other 3rd party libraries at run time (i.e. on Windows, the other libs will be available as DLLs whereas on Linux / OS-X etc they'd be shared objects, which are similar). For the sake of argument, one of those libraries is called "jack".
Obviously, our app can't guarantee which version of the other libs will be on the user's system (or even that they'll be installed at all). So our code is littered with statements like this:-
Code:
if (!jack_port_type_get_buffer_size) {
warning << _("This version of JACK is old - you should upgrade to a newer version") << endmsg;
} else {
some_var = jack_port_type_get_buffer_size();
}
We link to the latest version of jack, where that symbol is declared like so:-
Code:
size_t jack_port_type_get_buffer_size();
One problem is that it doesn't even seem to be an exported symbol (although that wouldn't affect the other platform builds). But apart from that, our customer might have an old copy of jack installed or even no copy! We seem to be making the assumption that if our customer has an up-to-date version, jack_port_type_get_buffer_size will be set to a valid address - but in all other case it'll be magically set to zero (there's nothing in our code that sets it to zero).
If there are two projects A and B. A is created as .dll, while B is created as static library.
project A has a class "classA"
classA: public classB {
public:
testA();
};
project B has a class "classB"
classB {
public:
testB();
} ;
I want to make a symbol of classB::testB() in A.exp (like ?testB@classB@@QAEXXZ), can I do it by using __declspec(dllexport)?
Also if I make classB as a template class, can the symbol of classB::testB() be generated automatically in A.exp when building project A?

I have such task. There is such alpahbet as {a, b} in markow algorithm concept. So I need to find out which letters (a or b) are more in word "p". If a then to retrieve the word with letter a, if-b-then word with letter "b", if there is equal quantity then 0. How to do it. Where to find such example, at least some clues how to begin.
