C :: Program To Get Series Of Integers From A User And Storing Those Values Into Array
Feb 10, 2013The problem deals with writing a program to geta series of integers from a user and storing those values into an array. Then use a function called selection_sort, when given an array with n elements, the function must sort the array from smallest to largest values.
I have code, and im trying to get it to compile but im getting these implicit declaration errors and conflicting types. Here is my code and the compiler errors.

C++ :: Calculate Angle Value In Form Of Trigonometric Functions - Loops And Void
Jul 24, 2013This is an assignment which the purpose is to calculate an angle value in form of trigonometric functions. These are the codes that I've wrote so far.
#include <iostream>
#include <cstdlib>
using namespace std;
void menu(double &value) {
system("cls");
cout<<"*****Trigonometry Program*****"<<endl;
[Code] ....
I have completed the codes for the interface part. Before I proceed with the formula for the trigonometric functions, I would like to make sure the program is Error-free, which if there is accidental invalid input from the user, the program would the user to enter another input until it is a valid response.
The only problem I have encountered for this matter was in menu(value)
If I enter an integer, the program will proceed without error. However, If I enter a character, the program will slip into an endless loop which constantly shows this
*****Trigonometry Program*****
Please enter an angle value => Is the angle in Degree or Radian?
Type D if it is in Degree
Type R if it is in Radian
Your response=> 0 //my initial input for value
Do you want to continue?
Type Y to continue
Type any other key to stop
Your response =>
Where is the source of the problem? I'm pretty sure it's the loop, but I don't know what to do.
C++ :: Menu Program Broken Down Into Series Of Calls To Function For Each Of Menu Items
Aug 19, 2013I am trying to write a menu program that will be broken down into a series of calls to function for each of the menu items. Two of the menu items will be simple programs which I wrote.
I want two of the functions to run one of the two programs I am trying to include as items in the menu.
So far I am only familiar with variables, loops, if statements, and I just learned how to write functions.
The problem I am have is that I don't quite understand how to write a function that will run one of the two programs. Also I am having a hard time writing the program in away that would allow the user to select the menu items.
C++ :: Loop With Taylor Series
Feb 25, 2015Write a function that computes the Taylor series expansion of ex using the following formula, where x is the exponent, and n is the number of discrete trials to run:
ππ₯=1+π₯+π₯2+π₯3+π₯4+β―+π₯π =βπ π₯π 2! 3! 4! π! π=0 π!
NOTE: This formula will NOT work if you calculate the numerator and denominator separately and then add the division result. You must use your knowledge of algebra to make sure youβre not calculating the entire exponent and factorial, but rather their factors per loop iteration.
Input prompt
Enter the values for x and n:
Output Prompt
Taylor series estimation is XXXX.XXXX
This is what I have so far for the function:
void getTaylor() {
double estimation
cout << "Enter the values for x and n:" << endl;
cin >> x >> n;
cout << "Taylor series estimation is" <<
}
I now need to create the loop so that I can enter in for my function.
C# :: Approximating Value Of Pi Using Leibniz Series
Oct 1, 2014Write a program that approximates the value of Ο using the Leibniz series and compares the Leibniz series approximation against the known value of Ο and two other common approximations of Ο (22/7 and 355/113). The program must prompt the user for the desired number of terms (n) to use in the approximation (as an integer) and calculate the approximate value of Ο to the given number of terms. The program must display each approximation of Ο and display the difference between each approximation.
I understand how to prompt for the number, what I don't even get how to start is to use it to approximate the value of pie in that given number. Also how to tell the difference between each approximation...
C/C++ :: Pi Approximation With Fibonacci Series?
Oct 11, 2014I can't seem to get the math portion right. It is supposed to approximate pi using (sigma,i=-1 to infinity)(-1)^(i+1)(4/(2i-1))=4(terms of pi). And what I have does some math but it is incorrect because I get a negative value for pi and one that is entirely too large at that. The precision is also to be at 20 decimal places. I also need it to end immediately after if I get an invalid input, but I can't seem to get it to end after trying a few different things it will say that it is an invalid number, but will continue to run the math loop. I also need the final cout to print all the terms that is multiplied by 4.

Visual C++ :: Calculate PI Value Using Series
Mar 3, 2013in code my prompt said :
(computing Ξ (PI) ) You can approximate (PI) value by using the following
series:
Ξ = 4( 1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 + ... - 1/(2i -1) + 1/(2i + 1)
Write a method that calculate value of Ο by using the above series, using
the following header:
public static double pi()
assume i = 1000000
ok so I have been testing it but I really did get any far :
for ( double i = 1; i< 1000000; i+=2) {
// with these I try to increment the value of i to get to the series. I did these after and test it and the output is all wrong and I know it
sum = (1/((2*i)+1));
sum = sum + (1/((2*i)-1));
sum ++;
double pi = 4*(sum);
// I know is wrong I but I can't figure it out what to do.
C :: How To Create A Program That Take AVI File
Jan 26, 2015I want to create a program that would take an AVI file, alter each frame (ex: change contrast, invert colors, etc.) and dump a new AVI. I've wrote a simple program for this experiment that loads up the header information from the video and dumps it. It also dumps a list of the frame data chunks within the 'movi' chunk.
The info I've gathered from coding this:
1. The recommended buffer size for each type of stream (vids, auds, etc.) is the size of the largest frame of corresponding type, plus 1 or two extra bytes.
2. numFrames in main header is the total number of frames for all types of data (video,audio,etc.) The 'length' value within stream header of type 'vids' is the number of video frames. The sizeImage value within BITMAPINFOHEADER is 921600 (==640*480*3) and the specification states that, quoth, "This can be set to 0 for uncompressed RGB bitmaps."
3. This video uses DIVX encoding.
Now my problem is this: How do I get the data within each video frame in a simple BMP like format? Even the uncompressed frames (with chunk id 'nndb') have variable sizes...let alone the compressed ones.
Information about a software that converts AVIs to a format with fixed sized uncompressed frames. Or at least some information about the frame decompression techniques.
Here's a dump made by the program for a 9 sec, 640x480 video I recorded from Pokemon. (Without the frame dump that is, it'd have made the post too long.)
Code:
AviMainHeader
-------------
size = 56
usecPerFrame = 66666
maxBytesPerSec = 7680000
padSize = 0
flags = 0x00000810
numFrames = 162
initialFrames = 0
numStreams = 2

C :: Program To Create 2D Array For Each Row
Feb 14, 2013What I am trying to do is to have the program create 2D array that for each row, no two numbers are the same and only consists numbers between 1-9. The array lists out every possible combinations. Supposely I do not know the number of possible combinations, I had it keep adding new rows until there are no more possiblities left.
The problem with my code is when I print out the completed array, it gives out really, really large numbers. But when I print the array from inside the first loop, it gives correct values. I do not know exactly what happened.
Code:
#include <stdio.h>
int main(void) {
int double_digit[1][2];
int a = 1;
int b = 1;

C :: Algorithm To Find Kth Term Of A Series
Dec 8, 2014I want to write an algorithm to find the kth term of a series given by the following recursive formula:
a_0=1 and a_(k+1)=a_k+1/k!
My code (part of it responsible for calculating the value of a series) does not want to compile:
Code:
float series(int n)
{
float F0 = 1;
float F;
unsigned int i;
if (n == 0)
return(1);
[Code]...
thus my question is why it does not want to work properly and what should i change (for certain factorial function is OK)?
C/C++ :: Print Series Of Text From Loop
Sep 29, 2014I'm attempting to print a series of text from this loop, but for some reason all I am getting is the sum total and the number 1, like this
1 5175.11
When I want to get it for each iteration of the loop. I've cycled over this and compared it to my other loops I've used and I'm lost as to why this isn't working. I also tried using a do while but that didn't work as well.
for (double total1 = 0; total1 < goal; total1 + save_amt) {
total2 = ((factor - one) * save_amt);
total3 = (total2 / fr_interest);
total1 = total1 + total3;
months_dis = (months_dis + one);
cout << months_dis << " " << total1 << endl;
}
C++ :: Lowest And Highest Number Of A Series?
Feb 26, 2013I'm having trouble, I want the inner loop to display the lowest and highest score. If I assign initial values for the high and low score, it won't always work (because if no/ all scores are above/ below my initial values...)
But without assigning initial values for highscore and lowscore, One of them will always be undefined during the first runthrough.
#include <iostream>
using namespace std;
const int AGRADE = 90;
const int BGRADE = 80;
const int CGRADE = 70;
const int DGRADE = 60;
int main() {
[code]....
how do i set this up so it stores a low and high score, and then compares those to each next number in the series?

C++ :: Create A Program Using Nested Looping?
Nov 5, 2013You are to create a program using nested looping. Your program is to have a menu asking the user to select which pattern to create and how many rows to use (it should accept 1 to 10 rows and keep the aspect ratio of the pattern). The patterns are 1 - Box, 2 - V, 3 - Inverted V. Note, if I select pattern 1 with 10 rows, the box will have 10 asterisks in the first row.
Okay so i came up with the box but i have been getting stuck at getting the V or inverted V.
