C :: How To Create A Program That Not Allow Negative Numbers
Sep 2, 2013I have a homework assignment due that told me for the "input specification" that "n" is an integer greater then 0. How would I put this in and where?

C++ :: Program That Uses Negative Numbers In A Conjecture Algorithm
Mar 6, 2013 I have to write a program that uses negative numbers in a conjecture algorithm. The program terminates when a number is reached that was already outputted. I can not get it to work and I have been racking my brain for a week.
#include <iostream>
using namespace std;
int main() {
int x[1000], y[1000], i=0, j=0, count=0, w=0, z[1000], t = 0;

C :: Program Crashes And Returns Random Negative Numbers
Mar 1, 2014I having some issues with two different programs here... One of them crashes and returns random negative numbers whenever it reaches a "fscanf" function and the other displays a "Polink fatal error: access denied" error.
Code:
/* Evan Wentz */
/* Pike - ET2560 */
#include <stdio.h>
#define MAX_ACCTS 100
int accounts [];
double balances [];
[Code] ....
I thought the reason this kept crashing before was because I didn't type the data into the text file it was writing too correctly, but I made another program to do that, and it crashed whenever it got to fprintf. Program works perfect besides the file stuff...

This program was made to allow students to enter as many test scores as they want and the program will show them in ascending order and then will calculate the average of all test scores. It works wonderful until you enter a negative test score and then it throws the averaging process off. I can't seem to be able to make the program not accept the negative numbers.
Visual C++ :: Ignoring Negative Numbers When Trying To Add Only Positive Numbers?

C++ :: Create A Program That Reads Numbers And Calculate Them On A Separated Subroutine
Nov 15, 2013I need to create a program that reads some numbers, and calculate them on a separated subroutine, and the return of this subroutine must be the sum of all the numbers. I'm getting an error but I can't figure out why =/

C :: Ignore Negative Numbers In Array
Feb 15, 2014So i have this program that takes in user input and stores them into an array and then prints them, removes duplicates, and sorts in ascending order. The user can also stop by inputting a sentinel value (in this case -1). But i am also supposed to ignore any negative value besides -1. When i input any other negative value into the program it messes up. How would i go about ignoring the negative values?
Code:
#include<stdio.h>
int main()
{
int input, nums[20], i, j, k, temp, count=0, count2=0;
for(i=0;i<20;i++)

C :: How To Correctly Multiply With Negative Numbers
Jul 24, 2013I've been working on this program to create a simple desk calculator for a school assignment, and I managed to finish. All we had to do was add, subtract, multiply, and divide positive integers - and I was able to do that just fine. This program got me thinking though, because I do not know how to write commands to multiply/divide negative numbers.
In fact, when I divide a number like 21 by 4, it comes out to 5 because I don't know how to allow it to compute remainders (which wasn't a requirement for my program). This intrigued me so I've been trying to figure it out for the last few days but to no avail. Here's my code:
Code: void flush_buffer(){
int ch;
while ((ch = getchar()) != '
' && ch != EOF);
[Code]....
And just know that my code works perfectly fine, I'm not here for troubleshooting it. I just want to know what I can change to allow negative values to be correctly computed.
C :: Negative Numbers Are Biased In Two Complement?
Mar 2, 2014I am reading one of the exercise solutions for C Programming Language: The C Programming Language Exercise 3-4
In it, it states that negative numbers are biased by (2^n - 1) (i.e. -I is represented by (2^n - 1) - (+I). So:
Code:
Bias = 2^8 - 1 = 255 = 11111111
Subtract 25 = 00011001
Equals = 11100110
what is meant by the "bias" here and what is the value of "I" here. It just suddenly uses "I" without explaining what it is.

C++ :: How To Get Rid Of Negative Number From Randomly Generated Numbers
Oct 21, 2013I have a error with one of my programs. I'm supposed to get rid of negative numbers when there are numbers that are randomly generated. Here is the middle part of the code.

C++ :: Average Negative / Positive Numbers And Total Average?

result.push_back(x);

array is a one-dimensional array of integers and n is the number of elements in that array that contain valid data values. Both of these are input parameters to the function. The function must calculate 1) the average of the n integers in array, storing the result in ave; 2) the average of the positive numbers (> 0), storing the result in avePos, and 3) the average of the negative numbers (< 0), storing the result in aveNeg.
void avgs (std::vector &array, int &ave, int &avePos, int &aveNeg) {
int sum = 0, pos_sum = 0, neg_sum = 0, pos_count = 0, neg_count = 0;

C++ :: Create Two Vectors With 10 Elements And Input Random Numbers
Feb 9, 2014I can't compile this code as I am at work and the computers are security protected, So i''l have to wait until i get home to test this, but I am pretty sure I am wrong. The problem is I have to create two vectors with 10 elements and input random numbers into it, then pick one of the elements of the second vector at random and append it to an element from the first vector at random. This has to be done 10 times and the I am assuming i have to print the 10 results. This is what I have:
