Not completely sure what you mean.

where are you defining the userIn1 in your main function?

Your porblem was : [code] Shapes::Shapes(char shape, int x, int y, int width, int height); <--THIS SEMICOLON { cout << "You created a: " << shape " shape. At X: " << x " At Y: " << y " Width: " << width " Height: " << height << …

"What the diffrent bettween while looping, conter-controlled while loop, sentinel-controlled while loop,flag-controlled while loop, do while loop and For loop. " Their syntax and spelling:)

short answer : change [code] void printtext(char **lotsoftext,int m,int n) [/code] to [code] void printtext(const char **lotsoftext,int m,int n) [/code] Just a side note, when your function does not change the content of its arguments thats passed, then make them const.

Yes, and if your compiler does not support the keyword export, then it has to be in the same file. (note not tested) For example : [code] //pair.h #ifndef PAIR_H_ #define PAIR_H template<typename Type, template Type2> class Pair { private: Type first; Type second; public: Pair() : first(0), second(0) { …

Its simple as this [code] float a = 3.1234567; float b = int (a * 1000 ) / 1000.0f // now b = 3.123 [/code]

Lets see what you are doing : [code] #include <iostream> #include <cmath> using namespace std; int main() { int a, result, factorial(a); //declare 'a' as an int //declare 'result 'as an int //declare 'factorial' as in int, initialized to //the value of 'a' which is ? junk... { cout << …

"I just want to have random numbers which are unique." So whats the problem. Are you stuck somewhere, trying to implement this? How about a trial and show us where/if you have problems. Since its only 5 numbers, you can create an array that holds say 5 elements. Then fill …

What you are doing is very dangerous! [code] bool *dat; //create a bool pointer dat=new bool; //set bool pointing to a address, i.e pointer-to-bool dat=true; //give value to the pointed address ++dat; //increase the address of bool. Huh-oh, but where is the //next address. Even worse, what does that address …

Now try a recursion functions for this job. 1) Find a base case. 2) Find a pattern. 3) Recurse pattern until base case is reached. Also no need to worry about the little details right now. Just keep it in mind.

not sure what you are asking for. Maybe some code would help.

when your display value reaches 60, you add 1 to minutes, and keep doing this until your minutes adds to 1 hour; Try this circular loop : [code] displayValue = ++displayValue % 60; min = displayValue % 60 + displayValue/60 hour = min % 60 + min/60 [/code]

Here is one way of doing it. [code] int Array[5] = {0}; int num(0); //the number the use will input; for(int i = 0; i < 5; i++) { cout<<"Enter value# "<<i<<": "; cin >> num; if( num >=5 && num <= 15) //put number into array only if its …

Yes its normal. The first window is from your compiler, and the second is where you render you objects. It will be useful when you need to debug you application.

common mistake : [code] while (qAnswer = 'y'); [/code] should be [code] while (qAnswer == 'y'); [/code] You understand the difference between '=' and '==' right?

Could you give us more information , so we can answer your question better. Not that most will hand you the answer without seeing you suffer:)

You might want to try a more general approach, where the user gets to input the number of rows for the tree.

Not sure what you mean. Maybe an example would help

I tried to install the devil library but I am getting some errors. Here are the steps that I am taking to install it : [code] Let me see if I did this correctly : Steps : 1) download DevIL 1.7.8 for windows 32 bit 2) extract the info to …

use ifstream then : [code] int main() { cout<<"Enter file name (with extension): " char filename[1024] = {0}; cin >> filename; ifstream iFile(filename); ...//do some stuff } [/code]

just to help start you off (from how I interpret the problem ): Steps : 1) declare variable for input 2) get user's input via cin 3) have a class ready to pass the variable to its consturctor 4) inside constructor decide which class the students get 5) print the …

I am using c++/opengl. Can someone help me with a wrapper for a 2d ball representation. I have one but its not complete. I need other stuff like momentum and collision response. Can you help me implement this?

How could one share a .exe that loads textures. I am using c++ and openGL. I want to share the .exe that I made using rapidshare.

Is there a way to reset the clock function?

I know that it returns the remainder but what happens when say : x% y, where x,y is int and x<y. I see that results in x; For example, 3% 101232 = 3 and similarly 3%y, where y is greater than 3 yields 3. Why is that> Just wonder the …

What you want to achieve will take a lot code than what you might expect. I would recommend to use '*' as un-fliped mode so the user wont get confused.

I just started a few days ago. I am troubled with the input in c#, even though I got it to work. Any comment would be helpful. Its a Number Guessing game and a tic-tac-toe game. [code] using System; namespace GAME { #region NUMBER GUESSING GAME public class Number_Guess { …

I am trying to rotate the object by a input of key. I dont know why the object is not rotating. I used glRotatef(x,0,0,1); //where x is declared as float : here is my code : [code] #include<GL/glut.h> GLfloat x = 10; void initGL() { glEnable(GL_DEPTH); glDepthFunc(GL_LEQUAL); glClearDepth(1.0f); } void …

Know : C/C++ Python java OpenGL DirectX Depending on you situation, your son should learn the list above , although c++ and opengl/directx should be more important than others. Also check out community colleges, and talk to them for what courses they offers, with regards to programming. Or even check …

how would you seperate a character in a string. For example : string ="2x^2+8" how would i seperate the string into '2' 'x' '^' '2' '8'. so I could find its derivative.

example of cin.get(). say a file called num.txt contains the following : 12345677700234. using cin.get() would first get the number 1, then it may be easier to imagine an arrow pointing to the number 2 , because the number 1 has already been extracted. Then using cin.get() again would ger …

hey, I am just learning textures in OpenGl, from a certain tutorial site : [URL="http://www.spacesimulator.net/tut3_texturemapping.html"]http://www.spacesimulator.net/tut3_texturemapping.html[/URL] the site had a good tutorial for texture, but after loading the .bmp picture, it goes to create its own function for vertex3f and such ( I think). In any matter, I have not learned …

i am writing a code that will rotate the polygon but it seem as if it is not working any help? [code] #include<iostream> #include<Gl/glut.h> #include<cstdlib> using namespace std; GLfloat fPent = 0.0; // for rotating pentagon; GLfloat fSqr = 0.0; // for rotating square; void handleKeyPress(unsigned char key, int x, …

I am practicing lighting and smooth shading. THe problem is that this code only shines the light for front and the right side , but when the objected is rotated, it shines at constant position (the front and right) and not to the side that are on the positioned light. …

You should look at the unit circle. So obj 1 has a velocity of 0 in direction 3pi/4(south) and you want it to face northeast towards the obj 2. so you need to rotate obj one anti clockwise on the angle pi/4. this is a hint try to figure it …

first off iostream.h is not standard so dont bother using it. use #include<iostream> instead. to solve your problem try doing this : [code=cplusplus] #include<iostream> using namespace std; //important. int main(){ cout<<"Hello world."<<endl; return 0; } [/code]

your problem is your cout statement. instead of cout<<mat[l]; it should be cout<<mat[l][k];

#include<iostream> #include<fstream> #include<cmath> #include<iomanip> using namespace std; /* 215 = 32768 and the sum of its digits is 3 + 2 + 7 + 6 + 8 = 26. What is the sum of the digits of the number 2^1000? */ //my logic is to export 2^1000 into a text …

hi, I am curious, how can I read a int from a text file( ex. num.txt). but this text file contains numbers without spacing (ex.1212132132313... 23156897984969.. 583852935792...) The problem is that this file has no spaces between numbers and when i try to read it into an arry, the result …
