I am guessing this is a string representation of a number. How can i remove these symbols. Since i need to reorder the integers, and print o...
My little brother is just getting into programming, and for his Science Fair project, he's doing a simulation of a flock of birds in the sky. He's gotten most of his code written, and it works nicely, but the birds need to move every moment. Tkinter, however, hogs the time for its own event loop, and so his code won't run. Doing root.ma...

Is it possible to find the greatest of two integers without any comparison? I found some solutions: if(!(a/b)) // if a is less than b then division result will be zero. { cout << " b is greater than a"; } else if (!(a-b)) // we know a is greater than or equal to b now. check whether they are equal. { cout << "a and b are equa...

I want to write a function that reverses the given string passed into it. But, I can not. If I supply the doReverse function (see code below) with a character array, my code works well. I can't figure out why this does not work. I am able to access str[0] in doReverse, but I can't change any value of the array by using a char pointer. A...
I am taking a beginning c++ class, and would like to convert letters between hex representations and binary. I can manage to print out the hex numbers using: for(char c = 'a'; c <= 'z'; c++){ cout << hex << (int)c; } But I can't do the same for binary. There is no std::bin that I can use to convert the decimal numbers to binary. H...
