C++ :: Program That Can Draw Total Of Passed Value
Feb 4, 2014
Draw the total of a passed value, or value in general, without checking how many values there are individually.
Here's a pseudo-example:
int aliens = 10; // This should be changed as desired.
void drawaliens(int value) {
aliens.draw(value); // Instead of having a test of how many to draw, draw the amount there is from one check
}
I want to draw the amount of aliens passed or called to the alien draw function.
However, I don't want the function to check every possible value of aliens which could be passed before drawing, and just check the value once and draw that value.
IF x ALIENS, DRAW x ALIENS instead of...
IF 1 ALIEN, DRAW ALIEN(1);
IF 2 ALIEN, DRAW ALIEN(2);
IF 3 ALIEN, DRAW ALIEN(3);
.... and so on.
If there can be hundreds of aliens, it seems impractical to check every single possible value before drawing, and just check the value and draw that value.
I missed last class on doing void functions because I got sick and im completely lost! ive being using the texts book example for a reference but its not running !
The output should look similar to this:
how much was your shirt? 20 shirt 20.00 tax =1.20 the total 21.20
Code:
include <iostream> #include <iomanip> using namespace std;
I am posting this simplified piece of code that is a bit confusing for me. There are two functions that I call. One shows the expected results but the result of the other one rather puzzles me.
Calling the function sum1 does not change the values stored in the variables val1 and val2. The output of the program is as follows:
val1= 1 ## val2= 10 // before the call of function sum1 val1= 1 ## val2= 10 // after the call of function sum1 sumOfVals= 22
This is quite obvious and as expected and I just pasted this piece of code as an example for better clarification.
However, if I call the function buildLaplacianPyramid and apply a function for Gaussian Blurring, this also effects the cv::Mat passed to the function. The line imshow("M1, after buildLaplacianPyramid",M1); therefore shows an image that is blurred. Since I am not passing a pointer to the cv::Mat I do not understand why this should be happening. I was assuming that there would be a copy of the cv::Mat M1 to be used within the function. Therefore I was expecting the cv::Mat M1 to retain its original value. I was expecting that all changes applied to cv::Mat inputmat within the function would not have any influence on the cv::Mat M1. Just like in my other example with the sum.
I need to create a program that will find the total of all the elements in array. I need to use for loop and the array size is 10.The output should be like this: i used user input
Write a program that calculates the total grade for N classroom exercises as a percentage. The user to input the value for N followed by each of the N scores and totals. Calculate the overall percentage (sum of the total points earned divided by the total point possible) and output it as a percentage. Sample input and output it as a percentage. Sample input and output is shown below.
How many exercises to input? score1: 10 total points possible: 10 score2: 7 total points possible: 12 score3: 5 total points possible: 8
Code: # include <iostream> using namespace std; int main () { double N=0, score, total, totalScore=0, totalGrade=0, GRADE; cout<<"How many excersices will be scored?/n";
I would like to make a program for calculating the total price of a game station, and a game. I made a program like this for just the price of a game in class, but I want to make one that does the game system as well.
I am fairly new to c++, and I want to be able to draw a polygon. When I have searched for how to draw one, the only thing i can find is scripts doing things like this:
* ** *** **** *****
I doubt that c++ is that primitive, and I'm looking for something like the c++ equivalent of this python script:
I'm trying to create a grid using the following characters: !, @, #, $, &.
It's an 8 x 8 grid, and should contain the characters in no particular order (trying to create a Bejeweled-like game).
I already defined the width and length to be 8, so:
#define WIDTH 8 #define LENGTH 8
Code:
void makegrid(char grid[]) { int j; int k; for ( j = -1; j < LENGTH; j++ ) { for ( k = -1; k < WIDTH; k++ ) { /* I don't know what to type here anymore :( */ } } }
This is my first time using opengl and I am experimenting with adding/drawing polygons/points/etc. on top of a PPM image. The image is already loaded when the application runs. My attempt to draw a square is from lines 30 - 35. The program runs but the square is not present. Just the image.
I want to write a function called DrawLineSegments.This function must change the color of lines at every corner where the corner angle is greater than 60 deg (Assume that there is a function called checkangle). The color sequence must be black, red, green, blue, and repeat this sequence after the fourth color.
I want to draw a magnifying glass using graphics.h which is used mostly as "Search" icon. But, I am having problems in making the rectangle attached to the two circles (one inscribed on another) . I have also included the screenshot (made in powerpoint) on how the output will look like, enen I've made most of the part, except the search icon (magnifying glass).
I used the following code. I called a method named lets_draw
private void lets_draw() { int i,z; z = 40; Line[] line = new Line[20]; for(i=1;i<=10;i++) {
[Code] ....
But it showed the following message
"An unhandled exception of type 'System.NullReferenceException' occurred in SkeletalTracking.exe Additional information: Object reference not set to an instance of an object."
Let's say there are three slots in my array (3 pieces of hardware to be used). If one worker comes in, it takes an instrument, and I tag it as used on random basis. Next, the next worker comes in, it takes another unused instrument randomly and so on. When the first worker finishes using that instrument, he returns it back to the inventory. How should I write such code in C++?
I am trying to create a program that reads my file filled with random words, it then compares the words after they are put into a 2d array and sees if there is any matching words.. unfortunately the count is not working for me (in function2 and function3) and I am not sure why..
Code:
#include<stdio.h> #include<string.h> char function1(char words_array[][17]); int function2(char words_array[][17]); void function3(int pairs, char words_array[][17]); int main( void ) { char words_array[20][17]; int x = 0;
I am writing a code that creates a deck of cards using a doubly linked list. One function, newDeck(), is made to create a new deck if the user wants. I don't have any problems creating the deck and it all seems to work fine, but when I run the whole program and a separate function needs to utilize the nodes in my deck, I get an error. Trying to find where there was a problem, I tried displaying the values of a card node in random parts of my code. At the end of the newDeck function, after the whole deck has been created, the card still displays correctly, yet when I return back to main immediately after newDeck has been called, I noticed that the values of my cards changed to either random values or they became null. I found this strange because in between the end of my newDeck function and at this point, there is no extra code so it doesn't seem as if there is any way the pointers could have been changed. Maybe It's because I don't have a complete understanding of pointers yet but is there any way that pointers can change values when returning from a function to main?
newDeck(head, tail, n); //this is how I call the function from main. void newDeck(Card* head, Card* tail, Card* n) //this is my function body { for (int i = 0; i < 4; i++) {
Im new to c#. In c++ I have made a window and painted it with dots and concentric circles, like a radar PPI screen. Trying to do this in c#, I can't find how to draw a single pixel on the window.
Also, what should I be drawing on: the form, panel, picturebox...?
I have a question about SDL and drawing sprites (SDL surfaces). My idea is that the user can create a wall of separate sprites by create one sprite each time in the current mouseX and mouseY position, when the user push down the e-key. The problem is that I have no idea how I could draw the same sprite multiple times without to delete the previous one.
I would like to draw a border arround a cell in a TableLayoutPanel but without also making a connection between the columns. I just want an outer border.
private void tableLayoutPanel1_CellPaint(object sender, TableLayoutCellPaintEventArgs e) { if (e.Row == 0) { e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Right, e.CellBounds.Top)); e.Graphics.DrawLine(Pens.Black, new Point(e.CellBounds.Left, e.CellBounds.Bottom), new Point(e.CellBounds.Right, e.CellBounds.Bottom)); e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Left, e.CellBounds.Bottom)); } }
This line
e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Left, e.CellBounds.Bottom));
also paints connections, where i don't want them. How can i just make a outerb order arround a cell and is there a easier way to do it? Here's also an image of what i want. I don't know if i described it right.
