C++ :: Calculating Sum Of Square Of Numbers Between Two Inputs
Mar 28, 2014
Write a function which takes two parameter of integer type and both parameters are positive integer. These number should be provided by the user of your program. The first parameter is lower than the second parameter. You function should be able to calculate the sum of the square of each of the numbers between the two inputs and should display that. Please write a main function to display the working of your function. Call the function at least three times by using some loop in the main function.
This is what I came up with but it is not correct:
#include <iostream>
using namespace std;
void sumsquares(int number1, int number2) {
int sum = 0;
for(int i = number1; i<number2; i++)
sum =sum+ i*i;
cout<<"The Result is: "<<sum<<endl;
How to calculate the values between numbers that a user types in.

Display the remainder of the square of numbers from 100 to 10. This square of numbers must be divisible by the numbers from 100 to 10 respectively. what i need to in this
I'm currently trying to write a program that takes an integer input from the user and displays that number of square-free numbers. I've gotten most of the program to work, but I encounter an error during the noSquare function that causes it to print incorrectly.
A square-free number is a number that is not evenly divisible by the square of any prime number. It's hard to see the bold in the code area, but it begins after the "//I think below is where the problem is"
#include <iostream> #include <vector> using namespace std;
I'm currently trying to write a program that takes an integer input from the user and displays that number of square-free numbers. I've gotten most of the program to work, but I encounter an error during the noSquare function that causes it to print incorrectly. I have bolded the area where I believe the problem is what I am doing wrong.
The problem with the program is that it prints ALL numbers from 1 to the input number instead of just the square-free.
A square-free number is a number that is not evenly divisible by the square of any prime number ....
#include <iostream> #include <vector> using namespace std; bool noSquare (int num); //Function to determine if the number is square-free vector<int> getPrimes(int num); //Function to get a vector of all primes below num bool isPrime (int number); //Function to determine if individual numbers are prime int main()
[Code]...
By the way, the in the middle of the code was me trying to bold a section, not an actual part of the code. I can't seem to find where to edit my original post.
I want to make program to square the numbers from 1 to 20. i have written this program, it's running but not giving the required answer.i think it is giving a garbage value...
void main(void) {int a; int b; b=a*a; for (a=1; a<21; a++) {printf("%d",b); printf("the square is%d=b"); } getche();}
I tried to check the rational or irrational numbers after we take the square root. i dont get the formula. for eg. squareroot of 64 is 8 and it is rational. square root of 2 is irrational. how to check it in c++..
Write a program that computes a running sum of inputs from the user, terminating when the user gives an input value of 0
Using a while loop - no problem. Its only when I try to code it with a for loop that the program doesn't terminate with a 0 input. It terminates with a -1 input!!
while loop
#include <iostream> using namespace std; int main() { float input=1; float sum = 0;
I have tried writing a code which takes two numbers from the user and calculates their square root then the roots are added up to return the sum. The program is coming out with loads of errors.
#include<iostream> #include<cmath> float main(){ using namespace std; float m1,m2,m3,m4,m5;
I am able to display a filled and hollow square by themselves, but I can't seem to be able to get them side by side.
So this is my code so far:
[/ #include <iostream> using namespace std; int main()
[Code]....
I can get the hollow square to show up, but the first square just shows up as a single line instead of a square. It seems that it ignores the first if statement in the second loop. I've tried not using an if statement in the second loop but it didn't seem to work either.
I've been working on this code that should be looking like
1 3 5 3 1 3 5 7 5 3 5 7 9 7 5 3 5 7 5 3 1 3 5 3 1
but mine appears like this
1 3 5 3 1 3 5 7 5 3 5 7 9 7 5 3 3 5 7 9 1 3 1 3 5
This is the code I've got for now, I just don't know which logic I need to fix
int main(){ int r; cout << "Rows?" << endl; cin >> r; for (int i = 1; i <= r; i+=2){ for (int j = i; j <= r+i; j+=2){ cout << j<< " "; } for (int k = i+2; k >= i-1; k-=2){
i have written a function that gives me the square root of a number. Yes i know there is already a function in <cmath> that gives square roots but i thought it would be pretty challenging (and therefore fun) to try writing one on my own. I wrote my code while i was in school, listening to my Irish teacher ramble on and on about useless shit, so it's probably not the best possible way of finding the square root of a number.
Having trouble getting my square to move to the left my code and instructions of what i am suppose to do is below. No sure how to move my square or if I am even going in the right direction as to writing code to do so. Note that it is only part of my code ( part 2 of project)
Part 2:
Write a graphical application that draws a square and then moves it.
Get the x and y coordinates for the top left corner of the square from the user using the get_int() member function of cwin. Get the length of a side of the square from the user using get_int() as well. Now draw the square to cwin according to the user input.Ask the user how many units to the left they want to move it using get_int() again. Then move the square, clear the screen, and draw it again.
// Part 2 // /* command output to declare the x,y value and 1 side length of a square through user interaction( Has user input intergers) */ int x_value = cwin.get_int("What is the x_value of the top left of the square?"); int y_value = cwin.get_int("What is the y_value of the top left of the square?"); int side_length = cwin.get_int("Input the length for one side of the square:"); /* Data type for the 4 corners of the square */ Point e; Point f;
My university assignment requires us to create a magic square. The definition of which can be found on Wikipedia and such, but essentially it's a (n) times (n) grid where all the row, column and diagonal totals meet the formula [n(n2 + 1)]/2. So a 3x3 would provide totals of 15 for example.
It's been requested that we use brute force for this, nothing mathematically fancy. I've succeeded in the task and initially during testing was coming up with a result of a 3x3 magic square after between 10 million and 1 billion attempts over a few minutes to nearly an hour.
I proceeded to refine my code and have as little as possible in the while loop which I'd break out of once the function had found a magic square, nothing really made much difference until I moved the declaration of my random to just before my while loop instead of within.
Random RanGenerator = new Random();
Once I'd done this I was getting 3x3 magic squares after a few thousand iterations in less than a second, which has completely baffled me. I can understand if it would save time, but how could that reduce the amount of attempts required to solve the magic square?
Found a good beginner's tutorial to learn Visual C++: [URL] ....
How to change the drawing so that instead of squares, the game draws circles. Can figure out that using Ellipse in the code results in circle outlines, but the fill remains as square color shapes.
The drawing code from the tutorial is below. How to substitute filled circles for filled squares.
Code:
// CSameGameView drawing void CSameGameView::OnDraw(CDC* pDC){ // First get a pointer to the document CSameGameDoc* pDoc = GetDocument(); ASSERT_VALID(pDoc); if(!pDoc)
I'm doing a project and I need to draw a square into a pgm image if certain conditions are met, but I'm not sure how to draw the square into the image.
I can't find a way to square and cube the number I want, which the number will show in the notepad. Is there a way to cube and square a number in my program??
I have an assignment that I have to make a 3x3 magic square that sums up to 15 on all sides. I can't use arrays, just Loops and If and Else statements.
My first attempt was like this
//Program for printing magic square that sums up to 15.
#include <iostream> using namespace std; int main() { int a, b, c, d, e, f, g, h, i; int r1, r2, r3; int c1, c2, c3;
[Code] .....
I can't think of a way to loop that when it prints out, it will have a sum of 15 on all sides and/or print one of the 8 solution for a 3x3 magic square.
In this assignment, you are required to write a function called largest square. Your function should take a 2 dimensional array, 2 integers which represent the number of rows and columns in the array, and prints out a 2 X 2 array which represents the largest square in the array. The largest square means the square for which the sum of its elements is the greatest in the array. Submit your function in a file called largestSquare.c
Example: Given the array 1 2 3 4
5 6 7 8
9 10 11 12 the output should be 7 8
11 12
Example 2: Given the array 8 2 6
3 7 3
6 1 1 the output should be 8 2
3 7
The prototype of your function is void largestSquare(int[rows][columns], int rows, int columns).
Am I anywhere close with what I've started?
// // main.c // largestsquare //
#include <stdio.h> #include <stdlib.h> int main(int argc, const char * argv[]) { int rows, columns;
