C/C++ :: Find Minimum Difference Between Two Pairs Of Integers In A List / Array
Jan 18, 2015
I'm trying to write a simple program that finds the minimum difference between two pairs of integers in a list/array. Of no surprise, it not work the first time I ran it so naturally i chucked in a whole bunch of print statements to debug
I encountered a peculiar error that is really stumping me.
#include <iostream>
using namespace std;
int closest_pair(int arr[]) {
int i=0;
int j=0;
int size=0;
int min=0;
I'm printing the size of the array in main and inside the function...and inside the function its giving me a size = 2 which is incorrect though the size printed in main is correct (size = 20). I further narrowed down the discrepancy to this statement: sizeof(arr)
So I am trying to find the min, max, range, mean, median, and mode. The max number is right but the min isnt. Once that is corrected, i can get range and mean easily. Also, how to get mode and median. I am guessing the values in the arr2 would have to be sorted. This refers to the values in arr2 which are the calculated values in the formula. You can enter -2 and 2 for userMin and userMax.
#include <iostream> #include <iomanip> using namespace std; int main() { cout << fixed << setprecision(1); float userMin;
Develop a function that finds the greatest difference between two consecutive elements stored in an array. Develop a 9 element array of doubles to test your code. Print to the screen which two numbers have the greatest difference as well as the value of the difference. Finally include an overloaded version of the function that will work if the array is composed of integers. Include your code used to test this function.
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.
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>
The method doesn't work properly, the point of the code is to tell the minimum value in the given matrix "m", it's supposed to take the first value of the matrix store it in min_ and then compare it to every value of the matrix, if the value stored in min_ is bigger than the current value in the loop then it's stored as the new min_ and at the end it's supposed to print that minimum...
Code: #include <stdio.h> #include <stdlib.h> #define SIZE 3 void minimum (int mat[SIZE][SIZE]){ int r,c; int min_; printf("
I'm a beginner at c++ and I need to write a program that reads a set of integers and then finds and prints the sum of the even and odd integers. The program cannot tell the user how many integers to enter. I need to have separate totals for the even and odd numbers. what would I need to use so that I can read whatever number of values the user inputs and get the sum of even and odd?
The program is to find intersection,union and difference of two sets. The program take the input correctly but after it crashes with the message that some exe is not working...
Code: #include<iostream> using namespace std; void Input(int *A, int*B, int size1, int size2) //input function {
I am trying to make my program read a bunch of numbers in an array to find its maximum and minimum. the program will ask the user to enter in as much number as possible until they enter a non number/letter. i got my program to find the maximum value but the program couldn't read the minimum value. it always says zero. also everytime i enter the number 0, the program will just finish its loop statement. If i typed in a negative number, it'll read the negative number as its minimum.
Code: #include <stdio.h> int main() { //-------variables------------------ double list[1000]; // can hold 1000 items int i; char letter; int max = list[0]; int min = list[0];
Let's say that in a txt file named hot.txt, I have this:
12,23,32
And with ifstream I want to take those number, adding one by one as integers in a linked list.
ifstream myList; char* p= new char; cin>>p; myList.open(p);
if(myList.is_open()) { char* x =new char;
[Code] ....
I know this part is quite wrong :
myList.get(x,256,','); // dafaq int num=atoi(x); list->addOrdered(num);
What I wanted to do is to stop before each comma and take that character and store it in the linked list and continue until the end of the file, but I couldnt.
I have a problem set where i have to read in numbers from a file as strings, convert from strings to integers, and pass the integers into a linked list, where each integer is a node. This is what I have so far:
Code: # include <stdio.h> # include <stdlib.h> # define MAX_INT_SIZE 10000 typedef struct integer BigInt; struct integer {
I am relatively new to C++ and am trying to bubble sort my linked list that creates 100 random integers. Everything works, but I am unsure how to continue this to include a bubble sorting method.
#include "stdafx.h" #include <iostream> using namespace std; class Node{ public: int data; //set data
I am supposed to make a program that take a list of integers from the user and to delete the smallest part of it in order to make it sorted in non decreasing order ..
I have a project to do in C and coming form Java I miss all the included features that are missing from C! I need to be able to store key value pairs in an quick and memory efficient manner. I've looked up using hash maps but I'm very new to C so don't really understand even the basic ones. I've looked at using a multi-dimensional array as I'm more comfortable with arrays but I'm unsure if that would count as a memory efficient and quick method?
But how would I do this using parallel_for_each (C++AMP) ? I need this for some algorithm that works with very long arrays and I think GPU would do this faster than CPU (even if I use all threads).
I am attempting to combine two vectors into a vector of pairs. I want to be able to alter the first and second of each pair and have those alterations reflected in the original vectors. I thought the following code might work but get compilation errors about a lack of viable overload for "=" for the line with the call to std::transform:
void f() { std::vector<int> a = {1,2,3,4,5}; std::vector<int> b = {6,7,8,9,0};
Alexandra has some distinct integer numbers a1,a2...an.
Count number of pairs (i,j) such that: 1≤ i ≤ n 1≤ j ≤ n ai < aj
Input
The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows. The first line of each test case contains a single integer n denoting the number of numbers Alexandra has. The second line contains n space-separated distinct integers a1, a2, ..., an denoting these numbers.
Output
For each test case, output a single line containing number of pairs for corresponding test case.
Constraints
1 ≤ T ≤ 4 1 ≤ n ≤ 100000 0 ≤ ai ≤ 109 All the ai are distinct
Example
2 2 2 1 3 3 1 2
Output: 1 3
Explanation
Case 1: Only one such pair: (2,1) Case 2: 3 possible pairs: (2,1), (2,3), (3,1)
as I understand the problem is just counting how many Ai's are 1 <= Ai <= N and then apply ((R*(R-1))/2), R is the count of valid Ai's
Problem is i dont know n so the solution must be recursive. The possible splits are 2^(n-1)-1. I am really stuck and most of the code is complete for cart and i really don't want to restrict it to binary values.
I am trying to perform columnSum and rowSum, as well as twoDadd and twoDSubtract using the arrays defined in my driver. How would I do that using A and B in my driver?
