C++ Project

[Natasha05]

Hi everyone, I have this project to do which I am unsure of how to approach. I need lots of helP. Thank You


Background: The project is a simplified view of micro-array data analysis. Micro-arrays and the analysis of their data are important endeavors in computational biology. Some of the computations are also similar to those used in digital signal processing and various forms of pattern processing (image, picture, photo, biometric, etc.)
Project Description:
1. In each of the following cases, the input data can be hard coded, obtained interactively, or read from input data file(s).

2. Write a C++ program that has as input data an M x N array (M > 64 and N > 64), with {0, 1} entries; hence such an array is called a (0, 1)-matrix; also used to represent adjacency, incidence, relationship, indicator, signature matrices. The program performs the following calculations:
a. Compute the number of 0’s and number of 1’s in each row
b. Compute the number of 0’s and number of 1’s in each column
c. Compute the number of 0’s and number of 1’s on main diagonal
d. Compute the number of 0’s and number of 1’s on the off diagonal
e. Compute the number of 0’s and number of 1’s on each diagonal parallel to main diagonal.

3. Write a C++ program that has as input data two M x N arrays, A and B, (M > 64 and N > 64), with {0, 1} entries. The program creates an M x N array C, with the following property. One of the arrays A or B can be regarded as a filter (mask) for the other.

a. Each C(i, j) entries are computed as follows:
C(i, j) = 0, if A(i, j) = 0 and B(i, j) = 1
1, if A(i, j) = 1 and B(i, j) = 0
2, if A(i, j) = B(i, j) = 0
3, if A(i, j) = B(i, j) = 1
b. Compute the number of each value in {0, 1, 2, 3} in the C array.

4. (Extra Credit) 3. Write a C++ program that has as input data one M x N array A, and one m x n array W, (M > 64, N > 64), (m < 10, n < 10). Both A and W have {0, 1} entries. W is to be used as a sliding window over A, by positioning or centering W(1, 1) over each entry A(i, j). In each case, the program computes the number of positions where the entries in A and W match.

This code might get you started with assignment 1. Seriously, you habe some nerve asking this on here. These tasks are not trivial problems and you don't even have any starting code to show us that you have actually attempted to try and create a solution, whether it's pseudocode or pure code.

class array2D
{
	public:
	array2D()
	{	
		array.resize(64);
		for (int i = 0; i < array.size(); i++)
			array[i].resize(64);
	}

	pair<int, int> ReadRows()
	{
		int ones = 0;
		int zeros = 0;		

		for (int i = 0; i < array[i].size(); i++)
		{
				for (int j = 0; j < array.size(); j++)
				{					
					if (array[i][j] == 1)
						ones++;
					else
						zeros++;
				}
		}
		return pair<int,int> (ones,zeros);
	}	
	
	private:
	vector< vector<int> > array;
};

Thanks a lot for ur help
btw im new on this n i thought this is the general C++ category...not beginners
n as u can c in my caption i said im unsure of how to approach it which is y i didn't put up a pseudo code
It ur gonna help you should at least do so genuinely ....

I never try to come off as an assface but you listed some seriously non-trivial problems. They aren't extremely difficult but they are also not extremely easy.

Is this for a job or is this for a school project?

[Natasha05]

So I should've posted it in the beginners forum?
Its for a school project.
Your reply looks like foreign language to me...thtz how i feel abt C++
I use Dev C++ normally.....is tht what you used

[IceThatJaw]

Dev C++ is just an IDE. IDE = Integrated Development Environment


C++ is all the same no matter what program you use to create a program.

If you don't understand my code than it's not the end of the word. Is it the "vector" parts that confuse you?

[BHX]

Is this for a job or is this for a school project?

Either way that is rather sadistic for giving a person who is fairly new to programming and C++. I actually got lost in what that was asking because of what all it said to do lol. I can completely understand Natasha05's frustration.

[Natasha05]

To me the entire thing is confusing.
Idk

Yah my professor is really harsh

[IceThatJaw]

2D arrays are pretty harsh.

If you play around with this code you might get a better understanding or 2D arrays. I apologize for using vectors. Vectors are actually easy to learn but you need to understand arrays first imo.

Play around with this code: ( put in cout statements everywhere)

int main()
{
		
	const int col_size = 5;
	const int row_size = 5;
	int array[col_size][row_size];

	for(int i = 0; i < col_size; i++)
		for(int j = 0; j < row_size; j++)
			cout << array[i][j];
		
		

	return 0;
}
