Chapter 2.4, Problem 2.53PP
Practice Problem 2.53 (solution page 160)
Fill in the following macro definitions to generate the double-precision values + ∞, –∞, and –0:
#define POS_INFINITY
#define NEG_INFINITY
#define NEG_ZERQ
You cannot use any include files (such as math. h), but you can make use of the fact that the largest finite number that can be represented with double precision is around 1.8× 10308.

c program question:Write a program to add elements of two 3x3 matrices and store it in third 3x3 matrix. Algorithm: 1-Read elements for Matrix A (3x3 Matrix). 2- Read elements for Matrix B (3x3 Matrix).3- Add elements of each matrix and store it in Matrix C (3x3 Matrix). 4-Display the elements of the Third Matrix Do the same procedure as that of Exercise 2.1. Input: Matrix A Input: Matrix B Output: Matrix C
Task - Encode a string (C Language)
Modify Project #2, Task #1 (given below) so that input characters are command line arguments.
Requirements
Name your program project5_encode.c.
Input characters are command line arguments. There can be any number of command line arguments.
Assume the total number of input characters is no more than 1000.
Character handling library functions in ctype.h are allowed.
The program should include the following function:
void encode(char *input, char *output);
The function expects input to point to a string containing the string to be encoded, output to point to a string containing the result.
The program should also check if the number of arguments on the command line is greater than or equal to 2. If the number of arguments is 1, the program should display the message "Invalid input!".
Examples (your program must follow this format precisely)
Example #1
$ ./a.out 7 + 8Output: 3_4
Example #2
$ ./a.out usf.eduOutput: ayl_kja
Example #3
$…
[Python (py3)]
Using import numpy as np, import sys, and def functions
Please create a code that solves for matrix addition, matrix scalar multiplication, and matrix multiplication
The input will come from file1.txt, and the output should be printed to output.txt
Note for matrix addition: When the dimension of Matrix A is not equal to the dimension of Matrix B, print "Matrix addition cannot be performed; dimensions are unequal."
Note for matrix multiplication: When the number of columns of Matrix A is not equal to the number of rows of Matrix B, print "Matrix multiplication cannot be performed; number of columns of Matrix A is not equal to number of rows of Matrix B."
Format of the input from file1.txt:First Line: type of operation (add or scalmultiply or multiply)Second Line: matrix A dimension (example: if 3 rows and 2 columns, type 3 2)Third Line: matrix A elementsFourth Line: matrix B dimension (or the scalar number for the operation of scalar multiplication)Fifth Line: matrix B…

- Objectives: practice with math, while-loops, sentinels, input validation, functions Starting with the provided file circles.py, write a program that uses functions to compute the area and circumference of a circle of a user-specified radius. The program consists of a main () function and two other functions, as follows: main (): Asks the user for the radius of a circle (floating point number). If the user enters a radius of zero, the program prints “Goodbye!" and ends. If the user enters a negative radius, the program prints “Invalid radius!", and asks again for a radius, and keeps asking until the user enters zero or a positive number. If the user enters a positive number, the program calls the two other functions and prints: A circle of radius R has circumference C and area A. (where R is the radius number, C is the calculated circumference, and A is the calculated area.) After printing the circumference and area, the program asks again for a new radius.
