Array Manipulation - Transpose of a Square Matrix: This program reads a matrix (two dimensional array), displays its contents, transposes it and then displays the transposed matrix. And here's the code
Basically i need to encrypt a message into ascii values & i also need to allow the user type some ascii values thus decrypting the values into characters that are placed within the code.
char array1[Q]={"A gentle, dull flickering flame, burns in the marble hearth. Its dim light scarcely illuminates the small, cozy room with its quiet elegance. The dismal light plays softly causing shadows over the solitary figure of a wooden desk at which Allen was roaming through his memories. Thinking back in the past where he once had a friendship which was out righteously incredible. She was the girl of his dreams, in a way which she had everything he had ever sought out in a beautiful and clever girl. Most of all she had his heart. Her style was incredible in the way the outfits she would wear would match perfectly giving a deep vibrant lively feeling."};
int S[Q]; char S1[Q]; int x; int i; char e, d; cin>>x; if(x=d){ cin>>Q; for(i=0;i<array1[Q];i++) cout << S[i]<<endl; for(i=0;i<array1[Q];i++) cout << S[i]<<endl; }
Consider a program that simulates a card game, with multiple player hands and a deck to draw from. Each hand can use an array to represent the cards it contains; sometimes it is useful to also declare an additional variable for each hand (or deck) indicating exactly how many cards are present.
1) Describe a simple function that would manipulate both the array representing a hand and the number indicating the size of the hand.
2) Describe a simple function that might be able to manipulate the array without referring to the hand size variable at all.
3) Generally, if the array was passed as a parameter to a function, how often would the hand size be included as a parameter?
I am having trouble understanding the mantissa of a floating point number. I have divided up the floating point number into the sign bit, the exponent and the mantissa, I have found the exponent, but I am not sure what to do with the mantissa? From what I have gathered so far i divide the mantissa by ten until I get a number between 1 and 10. after that i convert the number into a decimal with everything after the decimal point (or radix) being a fractional number. But when I do that on paper I dont get my intended number. How do i put the exponent and mantissa together to make a decimal from my floating point?
ex. input is 00111010000111111111011000001000 sign is 0 exponent is 01110100 which is 64+32+16+4-127=-11 mantissa is 00111111111011000001000 which would be 1.11111111011000001
When i convert that i get 1.99756622314 i dont know what to do with the -11 exponent and the answer i want is 6.1e-4
I'm trying to find the errors in my emulation of VGA VRAM concerning graphics modes.
(I'm testing it by doing plotting of all colors from x=0 to x=xsize-1 (where the color is relative, so 0=0 and xsize-1=maxcolor (in the case of 16 colors it's 15, etc.)))
VRAM Graphics management:

Why my output screen for this program does not want to stay open. It only opens for a split of a second and it's gone. The program is supposed to take numbers from a input file and display and save the manipulation in the output file. Here is the program.
I work on a system that communicates with other systems via messages. Those messages are defined in a spec and every word must be exactly as defined. To accomplish this Ada allows me to define the fields of my record to specific words in memory.
Code: word = 4; type Msg_Type1 is record x: Some_Type; y: Another_Type; z: Another_Type; end record;
1. Input an dimension and elements of an array from the keyboard. Count the odd elements of an array and that number join to variable K, then sort the last K elements in decreasing order.
Code: #include <stdio.h> main () { int A[100], i, n, j, K = 0; printf ("Type in the dimension of an array: "); scanf ("%d", &n);
Q.Write a program using user-defined function which accepts an integer array and its size as arguments and assign the elements into a two dimensional array of integers in the following format: If the array is 1,2,3,4,5,6, the resultant 2D array is
I just want to know the code of the program: Write code to accept matrix as aurgument and display its multiplication matrix which return its multiplication matrix.
I'm trying to copy my array 'block' to a 'dummy' 3D matrix so I can take out some arbitrary smaller matrix. Shouldn't this be possible with std::copy, where I'm certain the number of elements in the 1D array are equivalent to those in the dummy?
int dummy[210][210][1000]; std::copy(&block[0], &block[block.size()], &dummy);
but if the matrix is compressed_matrix type, there's something with it. the error log as below:
Check failed in file boost_1_48_0/boost/numeric/ublas/detail/matrix_assign.hpp at line 1078: detail::expression_type_check (m, cm) terminate called after throwing an instance of 'boost::numeric::ublas::external_logic' what(): external logic Aborted
Essentially what I need to do is take a text file, ("input.txt"):
4 4 1 0 0 1 1 1 1 1 0 0 1 0 0 0 1 0
And take the first two values on line 1 (4, 4) and use them as length and width. Number of rows: 4 Number of columns: 4
Then I need to print out the matrix and further manipulate it. I need to find the sum of the 1's per column and then take that number and replace each 1 with the 1's in each column.
The part that's mostly troubling me is that my instructor will be giving me the input file with random values, so I don't know what the matrix dimensions will be.
I can read the 2D array but can't seem to use it after. I need to find a way to skip the first line, and then read in the matrix and be able to use it mathematically to add up each column.
I have an array matrix called tmat,,and i know that in every row of tmax there are values which repeat two times...and am writing a code to extract the values WHICH DOES NOT REPEAT into another matrix called tcopy...the codes compiles fine...and it writes nicely to file...but without the desired result...
One last question...how can i get the array tcopy written to file in the form 5x3...and not all the figures in line one after the other? i mean i wish to see the matrix like a matrix on file..not like a list of numbers....
Code: #include <iostream> #include <fstream> #include <vector> using namespace std; const int R = 5; const int C = 5;
Use the linkedStackType class (Array implementation of stack) and write a function reverseCols to reverse the order of columns in the matrix. Note that reverseCols is not a member function of the Matrix class therefore only the public interface of matrix can be used.
//Implementation of Stacks as Array template<class Type> class stackType: public stackADT<Type> { public: const stackType<Type>& operator=(const stackType<Type>&);
[Code] ....
What is the correct solution must be to reverse the columns of the matrix?
First index of the second line tells the number of non-zero entries of the first row and second index tell the column number where the non zero entry is placed
