this is what i have so far

im trying to get the program to print this as an example if the user enters 5 (the rounding of the decimal is optional).
1 1.41 1.73 2 2.24
1 1.41 1.73 2
1 1.41 1.73

why its not reading my for loop for rows its only doing columns ...
I have tried writing a code which takes two numbers from the user and calculates their square root then the roots are added up to return the sum. The program is coming out with loads of errors.
#include<iostream>
#include<cmath>
float main(){
using namespace std;
float m1,m2,m3,m4,m5;

I am looking to create a table somthing like this output below but I am very new to this and my code is abit everywhere.

for example having input "12345556asf87" we get "123456asf". I need to do this task with getchar and putchar, and the with strings. My programs aren't working

Directions:Write a program that reads an integer n from the user.
Display the first 100 numbers, with newlines every n numbers, using % operator
#include <stdio.h>
int main(void){
int a = 0;
int b = 99;
printf("Enter a number: ");
scanf ("%d", &a);
[Code] ....
When I run this code it asks me to enter a number. It doesn't matter what number I enter it gives me the numbers from 1 to 100 in one horizontal line.
I want this program to do something like this:
for example if the user enters n=6 the program should give:
0 1 2 3 4 5 6
7 8 9 10 11 12 13
and so on
how to make the it all work later...but in the mean time how can i get this to display this? Note it has to be made using as a console program. The "Description" and "Cost/ib" collums will be referenced through use of a header file. all else is done by user input and calculations.

So far when I write the code I get 4 8 12 16 20 .... 96 all on the same line.
This is what I expect the code to look like if done correctly.

So I made a text file which goes like this
word word word word

(word is actually word I just didnt type them)
Now i figured out how to get the rows to work
#include <iostream>

#include <istream>
#include <stdio.h>
int main()
{
FILE* fp;
int countLines = 1;
int i;

I cant figure out column to work... Is it the same method cause im getting confused a lot!
How i draw such a thing in .TXT file using file handling. This output must be in columns and rows and in well arranged form.

Here's my code for adding the rows and columns. My problem is that my program displays an incorrect output.
main() {
int a[20][20],r,c,y,x,sum=0,rn,cn,cs=0,rs=0;
cout<<"Enter number of columns : ";
cin>>cn;
[Code] .....
This should be the output
Enter number of columns: 4
Enter number of rows: 3
Enter twelve numbers: 9 2 3 4 2 3 1 2 5 6 7 8
The numbers are:
9234

Sum of number 1 column is: 16
Sum of number 2 column is: 11
Sum of number 3 column is: 11
Sum of number 4 column is: 14
Sum of number 1 row is: 18
Sum of number 2 row is: 8
Sum of number 3 row is: 26
Im using apmatrix and im inputting values into a 4 by 4 matrix and im getting all these errors that have nothing to do with my cpp file so im guessing its apmatrixies fault. Also I put in the cpp and header file of both apmatrix and apvector into my project folder. Heres my code:

#include <iostream>
//cout, standard output
// <<, stream insertion operator

I am trying to sort a Report Table by which the user can enter any column or row number and output the results. And also sort by names as well. And from my code

#include <stdlib.h> /* srand, rand */
#include <time.h> /* time */

I know I need to start somewhere with a void function and put in a selection sort.
I have a N queens (actually 8 queens to be specific) program that accepts the numbers in order by row. I need to get it so it accepts the numbers in order by column. At first glance I thought it was just one space different, but it turned out not to be and how to get the one space difference in there. My current code (which I'm aware isn't doing the column accepting right) is:
Code:
#include <iostream>
using namespace std;
int main() {
int board[8];
cout << "Enter the columns containing queens, in order by column: ";
for(int i = 0; i < 8; ++i) {
cin >> board[i];
[Code]...
What the output should be:
Code:
Enter the rows containing queens, in order by column:
7

4

I am writing a program that deals with 2d arrays. The program inputs the number of rows and columns and asks for the entries. When the program run and compiles it works perfectly until it outputs then it gives me a warning.
Here is my code:

using namespace std;
int main()
{
int row1=0,col1=0,i,j;
//int a[row1][col1];
int** a= new int*[row1];

I am learning how to do this before I can move on so it can read a text file of numbers.
Also I am having problems with ////delete [] a[];///// I took it out because it made my code compile and run but when I add it in, it gives me an error:

I know this expression is suppose to deallocate the array.
I want to select three columns from my text file i.e. Empl No, Start Date and Created Date. After selecting this, I want to insert the data into a database.

{
string[] lines = File.ReadAllLines(filename);
for (int y = 0; y < lines.Length; y++) {
Console.WriteLine(lines[y].ToString());

I am trying to iterate a matrix in order to exchange rows and columns element by element. Although the function that exchanges the rows has come out well, i don't seem to figure out how to do the same on columns.The columns switch for a matrix like

1 2 3
if i try to switch column 3 and 2,is:
1 3 2

You will write a program that uses a multidimensional array having 3 rows and 8 columns and sorts each of the rows using both a bubble sort and a selection sort.
You must declare the array inside of main. You will have a for loop containing the calls to bubbleSort and selectionSort. You need to pass into function bubbleSort and selectionSort the following: 1) each column of the multidimensional array, 2) the size of the column, and 3) a particular row number of the multidimensional array to be used for printing out the "pass" shown on the following pages.
I keep getting an error that the identifier for bubbleSort and selectionSort is not found. (Error C3861)
Also, I feel like I'm missing something in int main() to get it to sort properly.
Code:
# include <iostream>
using namespace std;
int main() {
const int SIZE1 = 3;
const int SIZE2 = 8;
int arr [SIZE1][SIZE2] = { { 105, 102, 107, 103, 106, 100, 104, 101 },

how should i start?

Display the remainder of the square of numbers from 100 to 10. This square of numbers must be divisible by the numbers from 100 to 10 respectively. what i need to in this
View 3 Replies View RelatedWrite a function which takes two parameter of integer type and both parameters are positive integer. These number should be provided by the user of your program. The first parameter is lower than the second parameter. You function should be able to calculate the sum of the square of each of the numbers between the two inputs and should display that. Please write a main function to display the working of your function. Call the function at least three times by using some loop in the main function.
This is what I came up with but it is not correct:
#include <iostream>
using namespace std;
void sumsquares(int number1, int number2) {
int sum = 0;
for(int i = number1; i<number2; i++)
sum =sum+ i*i;
cout<<"The Result is: "<<sum<<endl;

I'm currently trying to write a program that takes an integer input from the user and displays that number of square-free numbers. I've gotten most of the program to work, but I encounter an error during the noSquare function that causes it to print incorrectly.
A square-free number is a number that is not evenly divisible by the square of any prime number. It's hard to see the bold in the code area, but it begins after the "//I think below is where the problem is"
#include <iostream>
#include <vector>
