Algorithm to print a matrix diagonally Let A be a matrix of dimension M x N. Minor diagonal of a matrix, divides it into two sections. A cell of the matrix will be *, if row count and column count are same. Given a matrix of n*n size, the task is to print its elements in a diagonal pattern. If we run the above program then it will generate the following output −. Given a matrix of n*n size, the task is to print its elements in diagonal pattern. If all elements in lower-section consists of zeros, it is a upper-triangular matrix and If all elements in upper-block consists of zeros, it is a lower-triangular matrix. The problem suggests we have to give a number n and generate a matrix of n x n and then we have to traverse the matrix in a diagonal pattern and store the values in a separate matrix.

For example, in the below matrix, the elements should be printed in the marked (in red) order, and the final output should be as shown below: Solution: We did a similar question yesterday, that was to print two diagonals of the matrix. See your article appearing on the GeeksforGeeks main page and help other Geeks. Given a matrix of M x N elements (M rows, N columns), return all elements of the matrix in diagonal order as shown in the below image. This cycle continues until the last element is reached. C program to Find Transpose of a Matrix. Program to print a matrix in Diagonal Pattern. For example, consider the following 5 X 4 input matrix. Program to print a pattern of numbers in C++. edit For Principal Diagonal elements: Run a for a loop until n, where n is the number of columns, and print array[i][i] where i is the index variable. For example: the matrix and its 2 diagonals are given below: In the above diagram, I have colored the elements in first diagonal as red and elements in 2nd diagonal as green. If n is 3 then to print a matrix in Diagonal pattern is −. It consists of N rows and columns (where N is the number of rows to print). I have matrix a[i][j] for example i = j = d (for example 3) . Similarly after upper-left half, we start from each cell of last row to print / diagonal for lower-right half of matrix. Print lower triangular matrix pattern from given array in C Program. (Please refer Example Input/Output section for more details). I have a simple program in which I want to print all of the elements in the secondary diagonal of the matrix - these are the numbers 5,9,13,-21,12 but the program does not work as expected. The idea is to start from each cell of first column of the matrix to print / diagonal for upper-left half of the matrix. Input Format: The first line contains R and C separated by a space. I am an embedded c software engineer and a corporate trainer, currently, I am working as senior software engineer in a largest Software consulting company . Step by step descriptive logic to print X star pattern. Example: Above is the source code for C Program to print diagonal elements of a Matrix which is successfully compiled and run on Windows System.The Output of the program is shown above . Hence run an outer loop to iterate through rows with structure for(i=1; i<= count; i++) (where count = N * 2 - 1). The pattern consists of exactly N * 2 - 1 rows and columns. If A=[a ij] be a matrix of order m x n, then the matrix obtained by interchanging the rows and columns of A is known as Transpose of matrix A. Transpose of matrix A is represented by A T. 1 2 3 4 5 6 7 8 9 10 11 12 How to print diagonals in c language, print diagonals in c program. Approach: From the diagram it can be seen that every element is either printed diagonally upward or diagonally downward. Multiplication of both Matrix is: 38 34 19 89 88 49 132 146 81. Hi i need to write c program to print the matrix elements in diagonal order, for example, int mat[3][4] = [ 0 1 2 3 4 5 6 7 8 9 10 11 ] output print s For each row stars are printed in four conditions. Program to swap upper diagonal elements with lower diagonal elements of matrix. Similarly, if the column number is equal to (size - row - 1), we will print one *. This article is contributed by Sahil Chhabra. Move to the next column or row (next starting row and column. Print Star Triangle in C - In c language you can print any star pattern, here you need nested loop first loop for print star and inner loop is used for line break. Entered second matrix is: 5 6 2 3 8 7 9 4 1. Almost all examples that I found were for c++ but I need to do it in C. I thought about cycle but I don't know how to use it. Do this till all the elements get traversed. Given a M x N matrix, print all its diagonal elements having positive slope. Program to check diagonal matrix and scalar matrix in C++. Create a matrix of size N X N which will store the pattern before printing. C Language Source Codes (C Programs) – Program to read a matrix and print it's diagonals.

HOME C C++ DS Java AWT Collection Jdbc JSP Servlet SQL PL/SQL C-Code C++-Code Java-Code Project Word Excel Given a matrix of order N*N, write code to print both the diagonals of that matrix. ; row and col – are the number of rows and columns respectively. For Secondary Diagonal elements: Run a for a loop until n, where n is the number of columns and print array[i][k] where i is the index variable and k = array_length – 1. Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above. Print Matrix Diagonally or Loop diagonally through two dimensional array or Traverse an array diagonally or print elements of Matrix in Diagonal order. You have to print the matrix in diagonal order. Read more Powered by Blogger Theme images by badins. First, we print the Upper Triangle. For example, for the first row, * is printed for the [first row,first column] position, for the second row, * is printed for the [second row,second] etc. What am I Write a program to input and display a matrix of size m x n, where m is the number of rows and n is the number of columns of the matrix. Next R lines contain C … The above pattern is a simple hollow square star pattern if we remove diagonal. Store the elements in the upper triangle of the pattern. Once the upper triangle is completed then store the elements of the lower triangle in a similar way as the upper triangle i.e. Alternate Implementation: This is another simple and compact implementation of the same approach as mentioned above. The task is to print the matrix of n x n of the diagonal pattern. Given a 2D matrix, print all elements of the given matrix in diagonal order. The task is to print the matrix of n x n of the diagonal pattern. How can I fill it with random numbers and then I need to show main diagonal and another diagonal over and below matrix. Writing code in comment? Our main mission is to help out programmers and coders, students and learners in general, with relevant resources … Given a matrix M of n*n size, the task is to complete the function which prints its elements in diagonal pattern as depicted below.
