- (Numerical) Heron’s formula for the area, A, of a triangle with sides of length a, b, and c is A=s(sa)(sb)(sc) where s=(a+b+c)2 Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of sand[s(sa)(sb)(sc)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A=1. The value of A should be returned by the function.(Statics) A beam’s second moment of inertia, also known as its area moment of inertia, is used to determine its resistance to bending and deflection. For a rectangular beam (see Figure 6.6), the second moment of inertia is given by this formula: Ibh3/12 I is the second moment of inertia (m4). b is the base (m). h is the height (m). a. Using this formula, write a function called beamMoment() that accepts two double- precision numbers as parameters (one for the base and one for the height), calculates the corresponding second moment of inertia, and displays the result. b. Include the function written in Exercise 4a in a working program. Make sure your function is called from main(). Test the function by passing various data to it.(Numerical) a. The following is an extremely useful programming algorithm for rounding a real number to n decimal places: Step 1: Multiply the number by 10n Step 2: Add 0.5 Step 3: Delete the fractional part of the result Step 4: Divide by 10n For example, using this algorithm to round the number 78.374625 to three decimal places yields: Step1:78.374625103=78374.625 Step2:78374.625+0.5=78375.125 Step3:Retainingtheintegerpart=78375Step4:78375dividedby103=78.375 Using this algorithm, write a C++ function that accepts a user-entered value and returns the result rounded to two decimal places. b. Enter, compile, and run the program written for Exercise 11a.

The valid operations of the calculator are: + add - sub * mul I div The program must contain a function fact with one input parameter that returns the factorial of a number, a function add that performs the addition of two numbers, a function sub that performs the subtraction of two numbers, a function mul that performs the multiplication of two numbers, a function div that performs the division of two numbers. The program must also check for bad input data. Make sure when you pass parameters you pass the addresses (not the value). • All function return type must be of type void. • Take inputs in main function. • Pass the addresses of the operands and the address of the result to each function. Output must be displayed as follows: 1: Addition 2: Subtraction 3: Multiplication 4: Division 5: Factorial 6: Quit Enter the choice => 1 Enter two numbers => 2, 3 Sum => 5-Functions Write a function int nth_Prime(int x) in C++ that takes a parameter x and returns nth prime number.
