Program Plan Intro
Approximation of pi
Program plan:
- Include necessary header files.
- Declare the namespace.
- Define the “main()” function.
- Declare the necessary variables.
- The “while” loop to execute the block of code at least once.
- Declare and initialize the necessary variables.
- Get the input from the user.
- Use “for” loop to iterate the “pi” value.
- Print the “pi” value.
- Declare and initialize the necessary variables.
- Get the “choice” from the user.
- The “if” loop checks the condition.
- True, “break” the statement.

Q 2 : Write a C++ program which inputs a number from the user, and classify it as even or odd.For sample output, use the last two digits of your registration number.
Using function(s), write a C++ program that computes the positive and negative sums of a set of MAXNUMS user-entered numbers(5 numbers), and displays the average of the positive and negative numbers. (Hint: be careful not to count the number 0 as a negative number.) Manually, test your program by entering the numbers 17, -10, 19, 0, and -4. The positive average your program displays should be x, and the negative average should be y.

- Numerical analysis) Given a number, n, and an approximation for its square root, a closer approximation of the actual square root can be found by using this formula: newapproximation=(n/previousapproximation)+previousapproximation2 Using this information, write a C++ program that prompts the user for a number and an initial guess at its square root. Using this input data, your program should calculate an approximation of the square root that’s accurate to 0.00001. (Hint: Stop the loop when the difference between the two approximations is less than 0.00001.)arrow_forward1- Write a C++ program to compute cosh z, given that: Assume the user inputs the value of z, and the series terminates at =66, Hint: xy can be found in c++ by pow(x,y).arrow_forwardThe ancient Greeks classified numbers geometrically. For example, a number was called “triangular” if that number of pebbles could be arranged in a symmetric triangle as shown in the figure below.

- (a) Write a C++ program to print all prime numbers within a given range (e.g., 1 to 100) by using afor loop and print all the possible prime numbers in the given range. Then print the total numberof primes. Third sum all the primes numbers within that given range. Use only for loop and print the output. Example output:Find prime number within a range:--------------------------------------Input number for starting range: 10Input number for ending range: 100The prime numbers between 10 and 100 are:11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97The total number of prime numbers between 10 to 100 is: 21The sum of all the prime numbers is = 1043arrow_forwardWrite a C++ program that calculates the Diagonal of a Square.

- (Computation) Among other applications, Pascal’s triangle (see Figure 7.22) provides a means of determining the number of possible combinations of n things taken r at a time. For example, the number of possible combinations of five people (n = 5) taken two at a time (r=2)is10. Each row of the triangle begins and ends with 1. Every other element in a row is the sum of the element directly above it with the element to the left of the one above it. That is, element[n][r]=element[n1][r]+element[n1][r1] Using this information, write and test a C++ program to create the first 11 rows of a twodimensional array representing Pascal’s triangle. For any given value of n less than 11 and r less than or equal to n, the program should display the correct element.
