Okay so I have to draw a square using "c" that draws according to the user input. Also, this has to be a function, and here is the code I have so far:
#include <stdio.h>
void DrawSquare(int length, char symbol);
void DrawSquare(int length, char symbol) {
int row;
int col;
[Code] .....
When I run this program it compiles fine but when the user input is recorded it just draws nothing but makes tons of spaces.
I have to make a program that displays a square of asterisks based on the users input. Here is what I have so far.
#include<iostream>
using namespace std;
int main(){
int number;
cout << "Enter a number: ";
cin >> number;
for (int i = 0; i < number; i++){
[Code] ....
But the square needs to be hollow like this. So if the user enters 5 then the following square will be shown.
*****
* *
* *
* *
*****
How to make it do this.
I know how to draw a square hollow or filled but i need to draw an alternating pattern ....
ex
iPatternHeight = 1
X
iPatternHeight = 3
OOO
OXO
OOO

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.

float m1,m2,m3,m4,m5;

I am trying to draw a grid for checkers. I could draw a square at the starting point from origin with the code below(attached the pic below how it looks) however I am not being able to draw a grid when the program runs.

// Shows how to place a piece accurately on a grid after a mouse click.
#include "ccc_win.h" // for graphics classes and functions
using namespace std;
int ccc_win_main(void) // main function for graphics program

I am doing an assignment that is to calculate the federal tax based on the users input. I am not entirely sure what it is doing, but it is definitely not what I want it to do. I commented out the loops because they seemed to have caused a problem, but there is still problems that are making the program do something else. Here is my code:
#include<iostream>
#include<string>
using namespace std;
double getData();
double taxAmount();
[Code] ....
Functions just seem like they are not my thing. It never gets to the second function to do the calculations and then return to main to display the results.
I tried changing the code to a switch(status) with a default: at the end that looped the "please try again" but for some reason, that was a fail, it created an endless loop.
My assignment is to pixelate an image based on users input. I have a structure that stores the image, and in this structure I'm storing the height and width and a dynamic array of RGBA struct.
This is my function. my main issue (that I've found) is offsetting and figuring out a way to handle the "edge" if the dimensions don't add up to the set pixelation size.
// @------------- Pixelation X
bool filter_pixelation(float percentageX, float percentageY, Picture& pic) {
// URL
/* 50% of 80 = (50/100) * 80 = 40 */
size_t perX = percentageX * (float)pic.width;
size_t perY = percentageY * (float)pic.height;
[Code] ....
Here is the getIndex function:
int getIndex(int x, int y, int width) {
return y * width + x;
}
how to stop outputting data based on a user input. The text file is as follows:
1. a
2. b
3. c
and the code I'm using is as follows:
int main (){
string line;
int search;
cout << "Enter a number from 1-3" << endl;
cin >> search;
search++;
ifstream myfile ("example.txt");
[Code]...
What I want to do is to just output number 1 (the whole line) if the user enters number 1. However, I get an error on the second condition w/c is the "&& line!= search"
I'm trying to create a function where it allows the user to type in multiple amounts of integers, so if the user wanted to have 3 different storages that hold different integers, the input would look something like this:
5
97 12 31 2 1 //let's say this is held in variable "a"
1 3 284 3 8 // "b"
2 3 482 3 4 // "c"
2 3 4 2 3 // "d"
99 0 2 3 42 // "e"
Since we don't know what number the user will input every time, I'm not sure how to create a dynamically allocated array that will create an x amount of arrays every time.. I want to be able to access each index of a, b, c, d, e or however many arrays there are.
So far, this is what I have, but I'm having trouble creating the arrays since it's unpredictable. I'm purposely not using vectors because I don't really get how pointers work so I'm trying to play around with it.
int* x;
int length, numbers;
cin >> length;
x = new int[length]
for (int i=0;i<length;i++)
{
cin >> numbers; //this doesn't work because it only grabs the first line for some reason
x[i] = numbers
}
I am trying to create a program that will calculate pi based on a user input for accuracy. If the user input .3 then when the leibniz infinite sum value at a particular i becomes less then the input of .3 then the loop will exit.
I have looked at a number of examples on the internet but I feel lost. I have put together working code that will infinitely output sums but I need the loop to stop when the sum value is less then the accuracy value.
My question is what is wrong with my while loop, why will it only give me infinite summations? How do I make it so that the loop will exit when my accuracy input is greater then the sum?
int main () {
double accuracy;
cout<<"Give an accurate number." << flush;//looks nice
cin>>accuracy;
int d;//initialize denominator
double pi = 0.0;
while(accuracy < d){

i want to display all the contents of a file excluding one based on user input say i have 4 records in the file numbered 1 to 4....the user chooses 2 to exclude it outputs records 1,3,4,4 when it should be records 1,3,4 what am i doing wrong here is the code.its basically displaying the last record in the file twice

I need to create a program that prints a certain number of asterisks based on user input. The user inputs 5 and I want my program to output "*****". How would I do this in C? I've tried printf("%#**", myvariable) but this does not work it only prints "*".

The program must be written to use the enum class_level :
enum class_level {FRESHMAN, SOPHOMORE, JUNIOR, SENIOR } ;
and define two namespace globalTypes (tys and fys) for the function :
class_level deriveClassLevel(int num_of_credits) ;
The function deriveClassLevel should derive the class_level of the student based on the number of credits earned.
The first namespace globalType tys should derive the class level based on a two year school policy.
and the second namespace globalType fys should derive the class level based on a four year school policy.
Four Year School Policy:
Freshman 0-29 creditsSophomore 30-59 credits
Junior 60-89 creditsSenior 90 or more credits
Two Year School Policy:
Freshman 0-29 creditsSophomore 30 or more credits
NOTE : use ignore() function with ifstream objects whenever you want to ignore the newline character.
For example :
ifstream transferSchoolFile ;
transferSchoolFile.open("student_status.txt", ios::in);
while( !transferSchoolFile.eof()) {
getline(transferSchoolFile,name) ;
transferSchoolFile >> id >> credits;
transferSchoolFile.ignore(); //Used here to ignore the newline character.

I am able to display a filled and hollow square by themselves, but I can't seem to be able to get them side by side.
So this is my code so far:
[/
#include <iostream>
using namespace std;
int main()

I can get the hollow square to show up, but the first square just shows up as a single line instead of a square. It seems that it ignores the first if statement in the second loop. I've tried not using an if statement in the second loop but it didn't seem to work either.
How can i repeat a loop based on the number inputted by the user?

I have an extra credit project where I'm supposed to calculate an approximate the user's age based on the current date and their birthday. My problem is that I am not getting the proper date and time. C++ keeps giving me some random date. I looked up c++ time format on the internet because this is extra credit and not in my book.

I will sketch the scenario I would like to get working below. I have one main application.
That application, based on user interactions, can load other applications in a secure shell. This means these child applications cannot interact with the OS anymore, nor with each other.
The parent program can at any time call functions of these child programs.
The child program can at any time call functions of these parent programs.
How to implement this in C++? Preferably both parent and child should be written in C++.
The performance of loading the child applications doesn't matter. The only thing that matters is the performance of the communication between child and parent.
I just don't understand how you would have it count how many negatives and positives there are based on the user's input? Here's the problem and the code it provides:
Modify the program so that is displays the average of the positive and negative numbers. (Hint: be careful not to count the number 0 as a negative number.)

#include <stdio.h>
