[Calculate grades’ average for a student] write a program that calculates the student grades’ average for a semester for the number of courses taken in that semester. Your program should do the following:
1.Read from user the number of courses (n)
2. Then, read the courses’ grades for n times (Hint: use a loop)
3.If a grade is grater than 100 or less than 0, ask the user to enter the grade again.
4.Calculate the average of grades using the following formula:
average = (sum of grades) / n
5.Print out the average grade on the screen.
Note: Always use appropriate data types.
(Financials: currency exchange) Write a program that prompts the user to enter the exchange rate from currency in U.S. dollars to Rupees PKR. Prompt the user to enter 0 to convert from U.S. dollars to Rupees PKR and 1 to convert from Rupees PKR and U.S. dollars. Prompt the user to enter the amount in U.S. dollars or Rupees PKR to convert it to Rupees PKR or U.S. dollars, respectively. Use c++ program.

- (Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input. Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number because 1 + 2 + 3 + 4 = 10 and 1 + 0 = 1, while 1235 is not (1 + 2 + 3 + 5 = 11 and 1 + 1 = 2). Write a program that prints out the first N magic numbers, seven on each line. Here is the sample output: You are required to use the following function prototype: bool isMagic(int value); // Returns true if value is a magic number The outline of this function will be as follows: Step 1: Calculate the sum of digits of value Step 2: Repeat Step 1 until we get a single digit Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise notarrow_forward(Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input.

- (Geometry: distance of two points) Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them. The formula for computing the distance is: Square root of ((x2 - x1) squared + (y2 - y1) squared) Note that you can use pow(a, 0.5) to compute square root of a.

- (Demonstrate cancellation errors) A cancellation error occurs when you are manipulating a very large number with a very small number. The large number may cancel out the smaller number. For example, the result of 100000000.0 + 0.000000001 is equal to 100000000.0. To avoid cancellation errors and obtain more accurate results, carefully select the order of computation. For example, in computing the following series, you will obtain more accurate results by comput- ing from right to left rather than from left to right: 1 1 1 1+ + 3 + ... 2 п Write a program that compares the results of the summation of the preceding series, computing from left to right and from right to left with n = 50000.arrow_forward(Count positive and negative numbers and compute the average of numbers) Write a program that reads an unspecified number of integers, determines how many positive and negative values have been read, and computes the total and average of the input values (not counting zeros). Your program ends with the input 0. Display the maximum, minimum, and average as a floating-point number. Here is a sample run:Enter an integer, the input ends if it is 0: 1 2 -1 3 0The number of positives is 3The number of negatives is 1The maximum is 3.0The minimum is -1.0The average is 1.25arrow_forward(Convert Celsius to Fahrenheit) Write a program that reads a Celsius degree from the console and converts it to Fahrenheit and displays the result.
