- a. Write a c program that asks a user for an integer. Declare a variable num3. Let num3 = --x; Display the values of x, and num3.b. Write a c program that asks a user for an integer. Declare a variable num4. Let num4 = x--; Display the values of x, and num4.a. Write a c program that asks a user for an integer. Declare a variable num1. Let num1 = ++x; Display the values of x, and num1 b. Write a c program that asks a user for an integer. Declare a variable num2. Let num2 = x++; Display the values of x, and num2.Write a program in C++ that lets the user input an odd number of positive integers ( each separated by one space). Assume that each integer except for one, the exclusive integer, appears an even number of times in the input. The program should output the exclusive integer. Example: Enter integers: 2 1 55 3 2 1 4 4 2 2 55 Exclusive: 3
- Write a simple program in C++ that lets the user input a single integer n where 1 ≤ n ≤ 100000. The program should print the sum of the first n prime numbers. In the first example below, the first 5 prime numbers are 2, 3, 5, 7, and 11. Example #1: Enter integer: 5 Prime sum: 28 Example #2: Enter integer: 100000 Prime sum: 62260698721In C++, write a program that inputs three integers from the keyboard and prints the sum, average, product, smallest and largest of these numbers. The screen dialog should appear as follows: Input three different integers: 13 27 14 Sum is 54 Average is 18 Product is 4914 Smallest is 13 Largest is 27Can you write a new code in C ++ language with the values I sent you, just like this output? There are two files named group1.txt and group2.txt that contain course information and grades of each student for each class. I will calculate each course average for each group and show in simple bar graph. Use "*" and "#"characters for group1 and group2, respectively. I will see the number -999 at the end of each line in the input files. This value is used for line termination and you can use it to verify that you have arrived at the end of the line. The averages of each group should also be calculated and printed at the end of the file. All of the results will be printed to the file. There will be no screen output. Sample output is shown in Figure 1.

- In C++, write a program that assk the user to input five decimal numbers on the same line, then do the following: Print out the five numbers (with spaces or tabs between them) Calculate and print the sum, average, and product of the numbers. All values should be rounded to two decimal places. Format the output such that all the values are right-aligned.In C++, write a program that checks whether there are duplicated numbers within three user inputted numbers, and return if "all the numbers are distinct", "all numbers are the same", or if "there are two are duplicated numbers."In C++ Please Write a program that repeatedly reads an integer value from the keyboard until the user enters a value that is divisible by 3 (it should not read additional values once a value divisible by three has been entered). The program should then output the sum of the values that were NOT divisible by 3. Sample Input 10 4 12 Sample Output 14
- In C++, an int is in the range 0 to 65535. But what if we need to add larger integers? Compute the sum 2345566777844567 + 9999988777765768009998. Write this function:string add(string a, string b) where a and b are strings expressing integers and the function add(a,b) returns a string signifying their sum. Strings a and b can have at most 100 characters. Write a main program that loops, asking the user for a and b. The program should terminate if the user enters “done” what asked for “number” a.In C, Given a char variable c that has already been declared, write some code that repeatedly reads a value from standard input into c until at last a 'Y' or 'y' or 'N' or 'n' has been entered.How to write a c++ program and run it N= 250, 500, 1000 times etc?
