Given two user input matrix. Our task is to display the addition of two matrix. In these problem we use nested List comprehensive. Algorithm Step1: input two matrix. Step 2: nested for loops only to iterate through each row and columns. Step 3: At each iterationshall add the corresponding elements from two matrices and shall store the result. Example code # Program to add two matrices using nested loop A=[] n=int(input("Enter N for N x N matrix : ")) #3 here #use list for storing 2D array #get the ... Read More
C++ is a middle-level language. It was developed by Bjarne Stroustrup in 1979. It is just an enhancement to C language and an object-oriented language. C# is modern and object-oriented language developed by Anders Hejlsberg. It is a part of the .NET framework. It is designed for Common Language Infrastructure (CLI). It is also a popular language. Difference between C++ and C# Both languages are object-oriented languages. C++ has low level of abstraction while C# has high level of abstraction. In C++, the program can be coded for any platform while in C#, the program is targeted towards windows ... Read More
To debug your code, you need methods or properties, which are provided by Debug Class in C#. The debugger class is used to set communication with the debugger. Debug Class The Debug class inherits from System.Diagnostics. The syntax is − public static class Debug The following are the properties of the debugger class. Sr.No Property & Description 1 AutoFlush Gets or sets a value stating whether Flush should be called on the Listeners or not. 2 IndentLevel The indent level is set 3 IndetntSize The number of spaces in the ...

To access the UNIX shadow password database, we should use the spwd module. We need enough privileges to access this file. The shadow password database entries are like tuple like object. To use the spwd module, we should import it using − import spwd The attributes of the shadow password database are − Index Attribute & Description 0 sp_nam The Login Name or the username of the user 1 sp_pwd The Encrypted password 2 sp_lstchg Date of last change 3 sp_min Minimal number of days ...

In 8085 Instruction set, DCR is a mnemonic, which stands for ‘DeCRement’ and ‘R’ stands for any of the following registers, or memory location M pointed by HL pair. R = A, B, C, D, E, H, L, or M This instruction is used to decrease the content of register R. Also we can say it will subtract 1 from the register R content. And the decremented value will be stored on to the register R itself. As it is an arithmetic instruction, so all flags, except Cy flag, are affected depending on the result. In those assembly ...

To verify UNIX password, we should use the crypt module. It has crypt(3) routine. It is basically one-way hash function based on the modified DES algorithm. To use the crypt module, we should import it using. import crypt Method crypt.crypt(word, salt) This method takes two arguments. The first one is the word and second one is salt. The word is basically the user password, which is given in the prompt. The salt is a random string. It is used to perturb the DES Algorithm in one of 4096 ways. The salt contains only Upper-case, Lower-case, Numeric values ... Read More
Var is strictly typed in C#, whereas dynamic is not strictly typed. Var declaration var a = 10; Dynamic declaration dynamic a = 10; A Var is an implicitly typed variable, but it will not bypass the compile time errors. Example of var in C# var a = 10; a = "Demo"; // gives compile error Example of dynamics in C# dynamic a = 10; a = "Demo"; // won’t give error
The termios module provides an interface to the POSIX for tty I/O control. It is only available for Unix system. To use the termios module, we should import it using − import termios All methods in this module, takes the file descriptor as an argument. There are some modules of the termios module, these are − Method termios.tcgetattr(fd) This method returns a list of tty attributes for the given file descriptor. The attributes are iflag, oflag, cflag, lflag, ispeed, ospeed, cc. Method termios.tcsetattr(fd, when, attributes) This method is used to set the attribute from the list of attributes. ... Read More
To change the terminal controls in the Unix system, we can use the tty related methods in Python. Using the tty module, we can set two different modes of the terminal. The raw Mode and the cbreak mode. To use the tty module, we should import it using − import tty There are some modules of the tty module, these are − Method tty.setraw(fd, when = termios.TCSAFLUSH) This method is used to change the terminal mode to raw mode. In the raw mode, the cursor moves to new line but the carriage return operation is not performed. Also ... Read More
In 8085 Instruction set, SBB R is mnemonic used for multi-Byte subtraction. Let us consider the following example on such subtraction In this above example, the subtraction of 62H and F1H will result in 71H with a borrow of 1. Next, we have to subtract 44H and 13H along with this borrow value of 1. In the above tracing we have shown you how the internal calculations are being done. Now in 8085, to facilitate such an operation, SBB instruction has been provided to subtract two numbers along with the borrow value. SBB is a mnemonic that stands for ... Read More
