Max Function

Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.

Power Function

A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:

Question

C++ program to check if a

// number is power of 2 or not

#include <bits/stdc++.h>

using namespace std;

bool isPowerOfTwo(int x) { return x && (!(x & (x - 1))); }

// Driver code

int main()

{

if (isPowerOfTwo(32))

cout << "Yes\n";

else

cout << "No\n";

if (isPowerOfTwo(31))

cout << "Yes\n";

else

cout << "No\n";.

(Civil eng.) Write a C++ program to calculate and display the maximum bending moment, M, of a beam that’s supported on both ends (see Figure 3.8). The formula is M=XW(LX)/L, where X is the distance from the end of the beam that a weight, W, is placed, and L is the beam’s length. You program should produce this display: The maximum bending moment is xxxx.xxxx The xxxx.xxxx denotes placing the calculated value in a field wide enough for four places to the right and left of the decimal point. For your program, assign the values1.2,1.3,and11.2toX,W,andL.

In C++ Language (please use hint) : Write a function which will swap its arguments if the first argument is greater than its second argument, but will not interchange them if the first argument is samller than or equal to the second argument. The function should return 1 if a swap was made, and 0 otherwise. (Hint: Make sure to use call by reference.) Write also a short test driver (i.e. a main() invoking your function).
1.)Implement a program using the if-else selection structure. Develop a C program that computes the different roots in a quadratic equation, aX + bX2=0. r = -b ± √ (b2 – 4ac) , r1 is the root when the + is used in the equation and r2 is the root when 2a the – is used. The roots r1 and r2 can only be computed when the discriminant (b2 – 4ac) is greater than the zero else the quadratic equation does not have any roots and therefore the program should display “no roots”. NOTE: sqrt is a built in function in C to extract the roots. The program will prompt to input the values of a, b and c and output the roots r1 and r2 or no roots at all. Check your answer manually. 2.) Implement a program using the if-else selection structure. Input two numbers. Determine and print the larger number, smaller number. Also, print the two numbers in ascending and descending order. Test data: Enter 1st number: 4 /*inputs */ Enter 2nd number: 2 Smaller number : 2…
