- (Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.(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.(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.
- Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)(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.*You need to have at least one user define function *Language: C programming Write a C Program to print half pyramid using numbers shown below.

- Functions & Loops : Case Studies Prompt the user to input two positive integers. Variables: firstNum and secondNum (firstNum must be less than secondNum) (use while loop); create a user-defined function called validateUserInput() to validate the user's input. Use Call-by-Value. validateUserInput() is a value returning function. Output all odd numbers between firstNum and secondNum. (use while loop); create a user-defined function called oddNumbers(). Use Call-by-Value. oddNumbers() is a void function. Output the sum of all even numbers between firstNum and secondNum. (use while loop); create a user-defined function called sumEvenNumbers(). Use Call-by-Value. Declare a variable called sumEven in the main() for the sumEvenNumbers(). sumEvenNumbers() is a value returning function. Use sumEven to hold a returned value. Output the numbers and their squares between 1 and 10. (use while loop): create a user-defined function called displaySquareNumbers(). Call-by-Value.…C Programming Problem : Write a C program with a function that takes an integer value (1 <- integer value < 9999) and returns the number with its digits reversed. For example, given the number 6798, the function should return 8976. Those two- original number and reversed number- numbers will pass to another function as parameters and calculate their sum. The program should use the function reverseDigits to reverse the digits and SumOriginalReverse to calculate their sum. Your output should appear in the following format: Output reverse digiS 4321 Main Enter a number between 1 and 9999: 6798 The number with its digits reversed is: 8976 6798 + 8976 - 15774 12.34 JomoriginalRevers Enter a number between I and 9999: 6655 The number with its digits reversed is: 5566 6655 + 5566 = 12221 Enter a number between 1 and 9999: 8 The number with its digits reversed is: 8 8 + 8 = 16 Enter a number between 1 and 9999: 123 The number with its digits reversed is: 321 123 + 321 = 444 Enter a number…: Write a function that adds two numbers.
