C++
1)Define a boolean variable and initialize it to true.
2) On the next line, display the value of the boolean
variable.
Example: The value of true is x
3) Set the above boolean value to false.
4) On the next line, display the value of the boolean
variable.
Example: The value of false is x
here is the C++ code for the following problem --
#include "iostream"
using namespace std;
int main(){
bool var = true; // step 1
cout << var << "\n"; // step 2
var = false; // step 3
cout << var << "\n"; // step 4
return 0;
}

[C++] Declare three Boolean flags and initialize it as with false value. Ask the user to enter a number, if the number is even make the first flag true, if the number is odd make the second flag true, and if the value entered by the user was not a number make the third flag true. Print out the values of the three flags along with a proper message telling the user about what he/she entered.
this is java 4. (2 point each) What value will be assigned to the "answer" variable below? If the expression will not compile in Java, explain why. Write your answer on the line to the right. a. boolean answer = 6 < 2 || 7 > 3; b. boolean answer = true && false; c. boolean answer = ! (87 == 80); d. boolean answer = true > false; e. String name = "Daniel" ; boolean answer = ! (name.equals("Charles"));...
C language not C++ 1. Write the statements to do the following: (2 pts) a. Define a struct with member variables width, height, topleft x, topleft y all floats). Use a tag to call it Rectangle. b. Declare a variable struct type Rectangle 2. Consider the following variables: struct int x; float y; char zi var1; union nt x; float y; char[20] z;) var2 f float and int are stored using 4 bytes each, what is the size (in bytes)...
Given a boolean variable a, are the following expressions equivalent? !( !a ) a 1) No answer text provided. 2) true 3) false 4) No answer text provided.
/** * Returns an array of booleans that are set true or * false based on the associated values in the array * arr using the following rules: * 1. If arr[i] is divisible by three then the boolean * value in the the array returned at the same position * should be true * 2. Unless the values in arr[i] is also divisible by 5, * then the value returned...
C++ pointers and linked lists 1. Declare an integer pointer variable intPointer. Initialize it to point to an int variable named someInt. Assign the value 451 to someInt and output (cout) the variable someInt and output (cout) the value pointed to by intPointer. Write an assignment statement that indirectly stores 900 into the value pointed to by intPointer. Output (cout) the value pointed to by intPointer and output (cout) the variable someInt, 2. Declare a pointer variable charArrPointer and initialize...

[III.4] You are given a boolean expression consisting of a string of the symbols 'true', 'false', and', 'or', and 'xor'. Count the number of ways to parenthesize the expression such that it will evaluate to true. For example, there is only 1 way to parenthesize 'true and false xor true' such that it evaluates to true. Complete the following tasks. [III.4a] Show the parenthesization of the example such that evaluate to true. 'true and false xor true' [III.4b] Show the optimal substructure...
