C++ :: Add Or Remove Integer To A Chain Of Integers Created By User
Mar 25, 2014
I got everything in this code running except for my remove function. What the project does is adds or removes an integer to a chain of integers created by the user. My add function works the first time but after that if I try to remove or add I believe it is pointing to the improper location and I don't know how to fix this....
Here is my code:
Header:
// adds "number" to the array pointed to by "arrayPtr" of "size".
// Note the size of the array is thus increased.
void addNumber(int *& arrayPtr, int number, int &size);
// removes a "number" from the "arrayPtr" of "size".
// if "number" is not there -- no action

I'm trying to find a way to remove an item that has been dynamically added when I change my drop down list selected user. The way this works is I add an edit and delete button dynamically when I select a user. I need to have the existing one be removed when I change users. Here is the code I'm using to build the two buttons. How do I remove them? Do I wipe out the columns and then add the columns again?
try {
dgvBG.DataSource = this.bgDataTableAdapter.GetData(cbPatientID.SelectedItem.ToString());
try {
Image editBGImg = Properties.Resources.editor;
Image delBGImg = Properties.Resources.del;
DataGridViewImageColumn btnBGEdit = new DataGridViewImageColumn();

I am having some problem with my quick sort problem. My program is supposed to create 5 arrays with 5,10,15,and 20 random integers, respectively. Then it should sort those arrays, where the numbers are bigger or smaller than the middle element in the original array! The program I wrote should do that but, its not! The program just keeps running infinitely!
#include <iostream>
#include <cstdlib>
using namespace std;
void p(int k[],int left, int right) {
int i = left, j = right;

How i can concatenate two integers into one integer. I have code that concatenate two integers but if the 2nd integer is zero it won't work. How can i modify it so that it can cater the case of y=0 too.
Code:
int concatenate(int x, int y) {
int pow = 10;
while(y >= pow)
pow *= 10;
return x * pow + y;
}

Using a do-while loop, for loop, or while loop. This is what I have so far but i don't know what to do after that.
#include <iostream>
using namespace std;
int main() {
int num;
int min = 2;
int max = 256;
}
Also the results should be printed out with 10 integers per line, right justified in a 5 byte field.

So I have a simple calculator that does a few operations (+ - * / %) Pretty basic stuff
I declared int x, y for the numbers, char operation, and float result.
the code is based on switch(operation)
The program is running alright, but when I divide 8/7 it returns 1 as the result, I tried changing the x and y to float but that won't work because of the case '%'
I also tried making local float variables in the case'/' but it won't compile "E2126 Case bypasses initialization of a local variable"
How can I make the division work and return a float value?

Write a program that reads four integers from a file ‘input.txt’.
The program will then create a single integer number from the four integers. The output of the program will be the single number and single number + 600.
#include <iostream>
using namespace std;
int main () {
int number , a;
cout<<"enter en integer number";
cin>>number;
cout<<"add 600 to the number"
cin>>a=number+600;
return 0;
}

a) Write a C-program that creates a chain of 10 processes and prints out their process ids and relationships. For example, process 1 is the parent of process 2, process 2 is the parent of process 3, process 3 is the parent of 4 and so on. Each child has to print out all her ancestors identified by the process ids.
b) Write a C-program that creates a fan of 10 processes. That is, process 1 is the parent of prcocesses 2, 3, 4, 5, 6 and so on.
I'm assuming that he means c++ since that's what we've been using. how to start this and what it means? Or where I can learn how to do this.

i have a work to do that consists on a given char pointer to a chain and a also given char pointer to a string. i have to search that chain in the string, and return the position where the beginning of the two it's equal. but only if they are equal.
example: string is "abcd" and the chain is "bc". want to find the chain, and if it exists, the position return will be 2. in the work it says that we should use sprintf() too. here is my code, which is incomplet yet.
Code:
char* pos(char* C,char* S){
char *str = S;
char *chain = C;
int i, j, temp;
int lengthStr = strlength(C);
int lengthChain = strlength(S);
}
[code]....
my doubt is how to use sprintf() and where. if i have to use malloc() and free(),
other examples:
pos(AGA,CTGCA)
return:
0
pos(AGA, ATAGATA)
return:
3
pos(AGA AGATAGA)
return
1 5

Ok, I got everything else to work in a two part exercise except for the 2nd part.
The first part had me take up to 20 grades, calculate total, average, and then list the grades with a '*' next to ones that were lower than the average... good to go.
Now in the 2nd part of the exercise I have to also associate a letter grade with the grades in the list. I have done a "if else" chain, but am having an issue with multiple arguments and not sure if I have gone the right route.
Code:
//Cameron Taylor
#include <stdio.h>
#include <math.h>
#define MAXARRAY 20

-Write a program using while loops that prompts the user for a set of integers.
-Your program will ask for one integer at a time. If the number 0 is entered, the list is complete and your program will output two results: the sum of the even integers and the sum of the odd integers.
-After each integer is entered by the user, your program will print out whether the integer entered by the user is less than, equal to, or greater than the previous integer. Assume for the first integer entered by the user that the “previous integer” was 0.
-Your program must handle a variable number of inputs (in other words, you cannot hard code for the test cases).
This is what I have so far:
#include <iostream>
using namespace std;
int main() {
int a;
int b;

For my code, I want the user to enter 4 integers, which get stored in an array. Here are the lines I wrote relevant to this part:
Code:
printf("Enter 4 integers:
");
scanf("%d %d %d %d," &a, &b, &c, &d);
z[4] = { a, b, c, d};
Would this be correct?

I know it would be easier to create an int array, but I want the program to create integers as the user requests. For example, if the user enters 4, the program creates 4 integers with the names input. Each integer is better as an individual integer, not an element in an array.I'm not sure if this is a possibility with C++.

This is the problem :- Write a program that keeps reading integers until user enters -1, then it prints the maximum and the minimum among all numbers (-1 should be ignored).

Write a program that asks the user to type 10 integers of an array. The program will then display either "the array is growing", "the array is decreasing", "the array is constant", or "the array is growing and decreasing."
(Hint: compare consecutive numbers in array and check whether it is increasing or not or constant) I wrote the program very well, but do I have to use "bool" like in c++ ? I haven't known how to code in c++ yet.So, I don't want to use "bool" in C.
I also wrote code about it but it looks like backslash and one,two,three,four,five how can I do it like this ?

So I'm supposed to write something that will output a multiplication table from two user input integers between 2 and 10.
For example it should display like this is the user inputs 4 and 5
1 2 3 4 5
2 4 6 8 10
3 6 9 12 15
4 8 12 16 20
I was hinted to used two for loops and this is what I have thus far, what I can't figure out is how to display it like the example.
#include <iostream>
using namespace std;
int main() {
int num1;
int num2;
cout << "Enter two numbers between 2 and 10." << endl;

Write a C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.
This is a sample output. Notice how the program prints a counter (1, 2, 3, ) for user keep track of how many numbers were entered so far. Include this feature in your program.
I have tried different ways to get the result from while loops, do while, and if-else statements. We have not done any max/min problem in class and the book was kind of vague. We have not learned arrays yet in class and I can't figure a way to compare the integers the user inputs as it is an infinite(from what I am reading) amount aloud. The problem I am seeing is the loop works and stops with the sentinel value but the INT_MIN is using the sentinel value. I also have not addressed the input of negative numbers yet with the first program I wrote, maybe one of my problems.
Code:
/*File:HW2Q3.c,
A C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.*/
/*header files*/
#include<stdio.h>
#include<limits.h>
/*****start program*****/
int main() {
[Code] ....
I have also tried this way as well, min value still comes back as -1 the sentinel value, and the else statement is being ignored. I am sure it is something silly but I am lost and confused at this point.

The 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.

I need to allow the user to input an integer of any length and print out the word of each number in the integer. So the user would enter "324562" and then the output would be "three two four five six two". I'm struggling to understand the best way to do it in C. I know I need a loop that goes through the int but I don't know how to do it

A problem that lets the user enter any positive integer, but you do not have to check for this, and then calculates the sum of the digits and displays this to user. For example, if user enters 14503, the outputted sum of the digits would be 13.
Here is my program
#include <iostream>
int main(void) {
int integer, sum=0;
while(integer) {
sum += integer % 10;
integer /= 10;
} cout << "The sum of the integers numbers is " <<sum;
return 0;
}

Return the digit at the user specified index of an integer. If the integer has n digits and the index is NOT in the range 0 <=index <n return -1 Start the digit numbering at 0. Example, if user input is 4 (index) and the integer equals 123456790 the return value for the function is 5 (start index at 0) ; if user input is 40 (index) and the integer equals 123456790 the return value for the function is -1
