(a && b) || (c&&d) only gives true when: any of a, b, c, d is true both a,b are true all, a, b, c, d are true a,b is ture or c.d is true O None of above

Need some help with example 4 please and thank you

4: Format.cpp) Write a program that gets two real values from the user, prints their sum and product in scientific notation, and prints their sum and product in fixed point notation. Print answers to three decimal places.

char, int, float and double 2. Given the expression b*b-4*a*c, write down its prefix notation and postfix notation.

68. Which one of the following have the same precedence? a. Addition and Subtraction b. Multiplication and Division c. Both Addition and Subtraction AND Multiplication and Division d. None of the mentioned

*Please help in javascript*   Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80     import java.util.Scanner; public class LabProgram {public static void main(String[] args) {/* Type your code here. */}}

Q1) Write a C code that outputs in the form of square matrices given as an example below according to the number of "N" entered. (“N" value presents size of (N x N) square matrix.) The only input should be the number "N" and output in the required order. Note: Be careful when the "N" value is even and odd.

Please code in python Kiki is making “Happy National Pizza Day” (February 9th) cards for all of her friends. She’s a bit disappointed with the cards not looking special enough, so she decides to add glitter to them to make them look more special. However, she’s short on glitter, so she decides to add glitter selectively. She uses a box with N*N divided sections to store her cards. Each section is huge and each card is small, so she can put multiple cards in a given section and they will never overlap. We model the way that she organizes the cards and adds glitter using two commands: Command 1:       1  x  y: add a card to the box in section (x, y). Command n:       2  x1  y1  x2  y2: Add one unit of glitter to each of the cards in the sections from (x1, y2) to (x2, y2). Help Kiki determine the total number of units of glitter that she placed on the cards. Input The first line will contain N (1 <= N <= 500) and C (1 <= C <= 500 ), the square size of the card storage box…
