Consider:
Code: template<unsigned int N>
class Test
{
private:

I just cannot understand why (clearly, we are calling <0, 0>, not <0, 8>). If I replace "N" with 8, it works as expected (at least for the beginning of the loop). I only tested on MSVC.
Is there any possible way of calculating some values at compile time? I have the following code of genereting upto 2000000010 palindrome numbers.
Code:
#include <iostream>
#include <string>
#include <sstream>
#include <string.h>
#include <stdlib.h>
[Code] .....
As you see, I have taken input from the user just after calculating the whole palindromes. So cant we calculate this at compile time? because runtime of this program is extremely slow.
Another qs. I first tried to use array but It didnt allow 2*10^9 sized array. so what should I do whenever I need that size of array?
My question is this: Is it possible to determine where functions are stored at compile time, so that at run time you can pass the memory address as a pointer to the interrupt handler so that it can directly call the function at memory location 'X'?
The newest project I'm working on would require to either somehow capture these addresses or to find a work-around so that instead of passing the pointer to the interrupt handler, the software would then need to be able to be non-interruptable.
Would there be anyway for the compiler, or the language, to provide a unique ID during compilation?
I've been using UUID generators, but I've always found the approach of copy pasting from a program to code to be kind of... limiting. If I want a random number, can't the compiler guarantee this for me?
It already does the same thing for anonymous namespaces, so...
I am working on a project, where I have to be able to exclude some code fast and dynamicly at compiletime.
I got a scheduler running and actually I just want to remove some of the tasks from it - but at compile time so that the code wont take up space in my microcontroller.
I know that I can use macros like #ifdef #endif etc. But I think that method makes the code unreadable and complicated.
How to archive such functionality a more elegant way?
So I made a library for a whole bunch of functions and when i compile it, it says"Unresolved external symbol_(Name of function here) referenced in function main.
View 1 Replies View RelatedI would like to have a program with a 5 mb string embedded in it kind of like this:
Code:
const char *c;
c = (const char*)"BEGIN_STRING_HERE, (5 MB of arbitrary values here)";
Is it possible to generate this string at compile time? Maybe with a macro? I'm trying to avoid a source file with a 5 mb string in it.
How do I set the size of a member array via the class constructor if I know the size at compile time. I can do this with templates, see below, but this leads to code bloats, I think.
So one class declaration but objects with different array sizes.
Can't use constexpr.
Can't use STL.
Can't use new.

so i have a loop that will run x number of times and each time it will produce a prize which is a certain sum of money. I need to a way to sum all the money earned. I am thinking there should be a way to extract the prize one for each time the loop runs but i am not sure how to do that.

i have two loops ie.
if (n==null)
{
do loop 1
}
else //(n=!null)
{
do loop2
}
now i have to update the above code, with a single loop ie. when n==null or n!=null do the loop 1
how can i update.?
can i do like this
if(n==null ||n=!null)
{
do loop 1
}
is || operator above does the job what i expected
I want to create a specific number of for loops each in another loop, as in example:
for(i=0;i<9;i++)
{
for(j=0;j<9;j++)
{
for(k=0;k<9;k++)
{
//some stuff
}
}

In this example there are 3 loops, but what if i want to create e.g. 10 such loops, and program reads a number of loops from a txt? It is needed for checking numbers.
I'm using an animation program. In this program I've simulated a particle system. The particles are flying around at different and varying speeds. I've attached birds to the particles and I want to be able to control each bird's flapping animation based on its velocity; so birds moving faster will be flapping faster.
Initially, the bird's flapping animation is controlled by a parameter that goes from 0 to 100%. So not only do I need to drive the speed at which the animation goes from 0 to 100%, I need to set it on a loop so once it reaches 100%, it loops back to 0%. I'm extremely new to code so I don't think it would be wise for me to even provide a jumping off point, not that I could.
I'm trying to make a percentage counter inside a loop, printing each completed percent of the loop as it goes. I've managed to write such code, but when I run it the percentage output breaks down (becomes negative!) for large loops. I have an example below.

Compiling and running the above yields the output:

If I change the value of N to 1e7 instead of 1e8, the output is correct however!

I am trying to make this while loop cut out / self break after 3 seconds. It is part of a simple game I am creating that gives the users 3 seconds to react otherwise it moves on to the next part.
while(1) {
key=getch();
if(key=='a'||key=='k'||key=='g') {
break;
}
}
All I need is it to end after 3 seconds, the rest of the code is working fine.
This sort of thing:
long startTime = System.currentTimeMillis(); //fetch starting time
while(false||(System.currentTimeMillis()-startTime)<10000)
If it IS for C, then I implemented it wrong or something.
I don't understand why my Do While loop skips over the input the second time round?

one of my project involves loop inside loops and creating random numbers. Here is what I have so far:#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
[Code]....
so the program will create a random value for the inflow. The idea is that the internal for loop will continue to run until the fill_level of the reservoir, which starts at 0, hits the capacity. The process of simulating how many years (each iteration of the internal for loop representing a year) is to be repeated 10 times by the parent for loop of the water_level simulation for loop.
The problem is that the random number that is supposed to created are the same number. THey are different every time I run it, but they are the same every time the loops repeat to make a new simulation.
We were discussing how to find average time complexity of different algorithms. Suppose I've a the following nested loop
for(int i=0;i<n;i++)
{
min = i;
[Code].....
Now the outer loop will iterate N times. the inner loop will always iterate 3 times no matter what the value of N is. so the worst case time complexity should be O(n^2) but what about the average case and the best case? I mean in terms of searching we can figure out and distinguish between the worst,best and average as it depends upon the number of comparisons. But here how can the average and best case be different then the worst case.

Consider the following:
Code:
float foo( float const *bar )
)
{
float temp;
temp = *bar;
...
}
Something I am noticing is that temp right after the assignment to *bar, is not the same value as *bar. This is for a project at work and the code runs on an embedded board with an ARM processor. I've copied the function into a standalone program for both Visual Studio and Code::Blocks and it works correctly there.
I'm writing a program that shows check fees for different amounts of checks. My other fees are showing up right but the .10 cents is not. It's showing up as .08 cents per check when I run the program.
Oh yeah the + 10 is for a $10 fee
Code:
else if (checks < 20 || checks >= 0) {
fee = .10 * checks + 10;
cout<< "Bank service charge for the month is $ " << setprecision(4) << endl;
}
For an assignment I have to create a random array of four integers, and then I have to allow someone to input up to ten guesses to guess the array in the correct order. I also need to be able to display whatever was generated by inputting -1. Finally, after every guess I have to tell the inputter how many of the guessed integers are correct and in the correct position, as well as how many integers are correct but not in the correct position.
So far I've been able to get the random array to generate properly, but inputting negative one has no effect, although if I input it four times in a row I get to my 'lose' condition. Also, it only seems to allow the user to input 4 guesses and not 10 before going straight to the 'lose' condition. I need to get these issues sorted out before I can move on to showing how many guesses are right etc....

I've even tried reversing the byte order of the test data, and I don't get the right result. I've tested the same data using C++ with CryptoPP on Linux, and I get the expected result, but I'm porting this code to run on .Net, and this is my main stoppage in the process at the moment.
