So I have an array portfolio [i][j] where i and j are determined by inputs by the user. I can get the code to fill the array with the correct values; however, I can not figure out how to output the array to csv.
Is there a simple way to output to a csv? Is it easier to create the csv file and just write to it?
I am writing a program where I read in data from a file into an array and a 2D array. However, when I cout that data to insure that it was all read in correctly, I get only the first full line of that input file(where there are actually 25 rows and 12 columns).
What am I doing wrong or should be doing differently?
ifstream fin; //open the input file fin.open("store_data.txt"); //If input file was opened, read input file data into array and 2d array if(fin){
At the bottom I have a loop that cout FI,XC,XL,I while going through the loop but when it prints its uneven and setw cant fix it. How do I print values of FI,XC,XL & I to an array so they are aligned.
I have an array of strings and a two dimensional array made up of floats. In the output for the strings (this array stores 10 divers numbers) I am getting only 8 of the numbers, then a core dump. What could cause this?
In the code that I am working on I am generating random numbers and assigning them a 2d array. But when I output the array in a separate nest of for loops the values are incorrect, but if I output the array in the same nest of for loops the values are correct
int spot[4][4]; int range[] = {1,16,31,46,61}, held[4]; void Generate() { for (int y =0; y<=4; y++) { for ( int x =0; x<=4; x++) { spot[x][y] = (range[x] + rand() % 15);
I want to create a function that will accept input from the user and return the input, to be used for further calculation. I know how to accept and return with integers as parameters , but how do i do it with arrays?
Suppose there is an array of numbers arr[]. Now, i want a function that accepts the input from the user, and return the array for further manipulation.
For example, if the array is arr[5], then i should call a function and accept the values from the user. Then, i should return the imputed values and print the same. How can i do this.
My program thus far is: (omitted code to shorten post and remove irrelevant information.
I don't know if it is because I have been working on other things and forgot how to proceed with the calculations and display, but I am just stuck. I'm not sure how to have the program read the numbers from columns 2 through 5 and then divide by 3. As you can see in my DisplayAverages() method I should have the ConsoleWrite and WriteLines done properly.
I have data that is coming into my buffer via popen (process data, not a file). Every seven records is a new set [0-6]. I am trying to 'print out the array line/element value' and 'change the value of element [2] to 0', but my loop appears to be looping through every character and not just every line?
so i got this piece of code today having some slight errors with it, how its actually done as i want to know where i have gone wrong here is the code .. Using a for loop to input and output array values
*/ #include <stdio.h> int main(void) { /* Declare an array of integers */ int Grades[5]; int nCount; /* Populate the array */ for(nCount = 0; nCount < 5; nCount++)
I tried to make this code to output an array in Ascending Order but the output is showing weird output like 001fgc123 multiple times instead of the array.
What is wrong with my code?
#include <iostream> using namespace std; void ascOrder(int Array[],int length) { int n=0,i,orderNum=0; while(n<length) { for(i=0;i<length;i++)
Here is my code and everything works except i can not get the highest array number to be output. it always says 10.
My instructions are:
(1) Create a 10-integer array called data (2) Set a pointer ptr to point to array data (3) Output the elements in array data using pointer ptr (4) Find the largest element in the array data using pointer ptr
#include <iostream> #include <cstdlib> using namespace std;
I have a 3x3 array which is filled up of random numbers, the limit being set by the user. So if the user chooses 3, the array will be filled up of 1s, 2s and 3s randomly. That bit is fine.
So when I display the array I use:
Console.WriteLine("The values in the 2 dimensional array are: "); foreach (int number in twoDimensional) Console.Write(number.ToString() + " ");
The output will then be 3 3 2 1 3 1 2 3 3. Is there a way I can display it like:
Write a program to read in a sequence of characters one by one. Print out the characters in reverse. You should use a char[]. (Remember single quotes are used for char)
For example:
Please enter characters one by one: (Enter 0 to exit) h e l l o 0 You entered: hello. The reverse of that is olleh.
and this is currently my code
#include <iostream> #include <cstdlib> #include <cstdio> #include <ctime> #include <cmath> using namespace std; int main() { char entry[20];
[code]....
im just not sure how to set that value and still make the for loops work

I've been in a strange problem. Im in need to have a dynamic character size, but that increases the outputsize of my program by almost 50kb. (while the program was 11kb previously).
How to traverse through this array and output each student and score that falls below the average. I think I may have the method down for traversing through the list to find the "total score" however, before proceeding under a possible wrong presumption, I would like confirmation as to whether or not I'm understanding this or botching this concept.
void dispLowScore(struct payload *arrayStart , //first element of array struct payload *arrayEnd ) //last element of array { int studentCount; //total number of students in list/array int totalScore ; //accumulated value of all scores added together float averageScore; //totalScore / studentCount
I have this code that im stuck on what i need to do is Extend the code such that when it starts the user is asked to input values to specify each of the three ranges before moving on to accept and tally the main values how do i do that Using a for loop to input and output array values Also calculate the average
*/ #include <stdio.h> int main(void) { /* Declare an array of integers */ int Grades[5]; int nCount; int nTotal = 0; /* Declare and initialise the value */ float fAverage;
I am writing this program that is supposed to read a file, put the data into an array, alphabetize, count how many times each word appears and print to an output function. I posted before on how my program had an error when I ran it but I have fixed that. Now my outputArray file is empty. It gets created but there's nothing in it.
How to output vector contents using the push_back function. My program reads in values just fine, but it does not output anything and I've been stuck on why.
here is my code:
#include <iostream> #include <array> #include <vector> using namespace std; int duplicate( vector < int > &vector1, const int value, const int counter)
