C/C++ :: Printing Asterisk Along A Function Of Y Columns
Jun 18, 2014
The assignment is to plot the functions, by implementing a function having the following prototype:
void plotPoint(double y);
This function should print a single "*" symbol, in a position determined by the value of y, and then a newline. The position of the * symbol can span over 80 columns: each column should represent a delta of length 0.1 in the value of y, and the zero should be placed on the 40-th column.
For example:
• placePoint(0) should print the * symbol on the 40th column
• placePoint(0.1) should print the * symbol on the 41st column
• placePoint(1) should print the * symbol on the 50th column
• placePoint(-1) should print the * symbol on the 30th column
Here is what I have so far:
#include <iostream>
#include <cmath>
int a;
int b;
int x;
int y;
int Func1(double a, double b )/>
[Code] ....
I'm lost now as to where to go to plot. I know that depending on the option chosen I call the corresponding function to return a value for y which is just then plugged into a function to plot it on columns of y.
I'm working with arrays and I get them column by column and need to print them. I as there a way to print in columns?
For example: I produce an array of A, B and C from a loop and then need to print them in one column and the go to the next column ....
so in the end I shall have an output like this:
A E B F C G D h ... ...
My arrays are too long (over 50K) so I cant just store the arrays and then print them. I need to produce each column array, print them and delete it and go to the next column.
From my understand the cast (reg8 *) applies to the result of the bitwise OR. But what is the left most asterisk doing?Is it just dereferencing the casted pointer?
i have to make a programs that prompts the user to enter quiz grades and add them up. For examples the user enters 6 test grades they are out of 5 so he enters 0-5 and i store them in the array. This part works great but now i have to print out a bar of vertical asterisks for every part too. So if at the end we have one test grades that are 2 grades of 1 points, 1 grade of two point, 2 grades of three point and 1 grade of 5 point it will have to display them as this
There are 2 grades of 1 There are 1 grades of 2 There are 2 grades of 3 There are 1 grades of 5
i need to do for loops but i am stuck on what to count too and what to print i know i will need cout << "*" and a couple of spaces.
#include <iostream> using namespace std; int main (){ int size; int tests; int a[6]={0};
cout << "How many quiz scores will you enter: "; cin >> size;
i have my basic C program here (i'm new to C language):
Code:
#include <stdio.h> int main() { int grade; int A=0; int B=0; int C=0; int D=0; int E=0;
[Code]....
As you can see, it's only for counting how many students got the grades from A to E, but the problem is that i need to change it from numbers into asterisk
for example: 4 students got the grade A, and 3 students got the grade B
I have to convert a binary value from an input file (the name of which is given by the user) and then convert the binary to decimal value and print that in an output file.
Right now it is compiling just fine with no error messages, but when I run the program, it doesn't end or print to the output file.
So, I'm going to write a recursive function for a asterisk pattern but I'm stuck figuring out how to create a stopping case for it, better yet, I'm unable to describe the pattern completely.
* Every odd row has 1 * with 1 incremented white space
* Every "pair" of asterisks equals 8 total (EX. 8 one pair *'s, 4 two pair *'s, 2 four pair *'s)
Unfortunately, that's all I got. how I can represent this as I function. Once I figure out what my stopping case should be, I think I can do the coding on my own.
-Write a recursive function that prints an integer with decimal separators. For example, 12345678 should be printed as 12,345,678.
The problem is that I don't know how to modify the integer in such way. I was thinking to convert it into a string, do an algorithm and then turn the string back to integer.
This program needs to display a vertical graph of asterisks showing production for each plant in the company ...
Here is what I have so far:
*********************************** This program will read data and display a vertical graph showing productivity for each plant. Reference Display 7.8 pg. 401-3 *********************************** */ #include <iostream>
I have this code it sums the rows now I need it so it would sum all the columns in the output and put it in row 8 of the outcome. How would I go about doing that?
Code:
#include Code: "stdio.h" #include "stdafx.h" int main(void) { int number[8][7]; }
I have this code down except I'm very confused how to make the output come out in 3 columns.
#include<iostream> #include<fstream> using namespace std; int main() { int i, j, n, flag = 0, prime_number = 0, temp; cout << "Enter first prime numbers that will be used or -1 to end:" << endl; [Code] ......
My output right now is:
Enter first prime numbers that will be used or -1 to end: 20 Twin Prime Number : (3,5) Twin Prime Number : (5,7) Twin Prime Number : (11,13) Twin Prime Number : (17,19)
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.
I have a basic question regarding 2d vectors. The following code makes a 2d vector and fills it with a matrix of integers. The vector tempVector3 gets added as a new row to the matrix. But what if I wanted to add the tempVector3 as a new column instead. How would this be done in the simplest way?
#include<iostream> #include<vector> int main(){ std::vector<std::vector<int>> numbers; std::vector<int> tempVector1; tempVector1.push_back(2);
I have a file that can range from 100 rows to 10000+ that is comma delimited with 8 columns. The first 32 rows (also comma delimited) will always be ignored (geographical header information). I will be wanting the data from column2 and column3.
For this I believe I would need (2) For Loops as such:
I have this code down except I'm very confused how to make the output come out in 3 columns.
#include<iostream> #include<fstream> using namespace std; int main() { int i, j, n, flag = 0, prime_number = 0, temp; cout << "Enter first prime numbers that will be used or -1 to end:" << endl; cin >> n;
[Code]...
My output right now is:
Enter first prime numbers that will be used or -1 to end: 20
Twin Prime Number : (3,5) Twin Prime Number : (5,7) Twin Prime Number : (11,13) Twin Prime Number : (17,19)
But what I want is: 1. {3;5} 2.{5,7} 3.{11,13} 4. {17,19}
I'm having trouble trying to get my loop program to display multiples of 4 in rows and columns. My objective is to print multiples of 4 that are less than 100 in a 4 by 4 format.
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.
Ok so I'm working with a windows form in C# and sql server database. I'm trying to do something like what is in the image below using a datagridview. My question is how do I 1) ensure only 1 checkbox is checked per row 2) do math that 'links' a checkbox column with another column, and add the totals. I understand that asp.net and web forms would be easier but we have not reached that point in the course yet. Would this be on the right track:
foreach (DataGridViewRow row in dataGridView.Rows) { if ((bool)(row.Cells["Checkbox"]).Value || (CheckState)row.Cells["Checkbox"].Value == CheckState.Checked) { // Do something } } Attached image(s)
