Write a program to check if a number is a prime number. 1) let user input a number 2) check if its legal input (must be greater than 1), if not, ask the user input again until the input is greater than 1. 3) check if the number is prime 4) print "it is prime" or "it is composite". (A natural number (1, 2, 3, 4, 5, 6, etc.) is called a prime number (or a prime) if it is greater than 1 and cannot be written as the product of two smaller natural numbers) prime number only has divisors, 1 and itself.

Loops, C++ Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 5 as long as the value is less than or equal to the second integer. Ex: If the input is: -15 10 the output is: -15 -10 -5 0 5 10 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last.
.Write a program that reads the integers between 1 and 50 and counts the occurrences of each. Assume the input ends with 0.
C++ Question Write a program that reads any 5 numbers as in the given sample of output below: Sample of output: Enter any 5 integer value. 1 2 -1 3 0 The number of positive value is 3 The numbers are: 1 2 3 The number of negative value is 1 The numbers are: -1 The 0 number is 1 The total is 5.0 The average is 1.25
1. Write a program that asks the user for the price of several items sold until the user answers with an “N”. The program should accumulate the total of all prices entered. After the loop is finished, the program is to compute the sales tax of all items as 7% [0.07]. Finally, the program is to print out the total of the items, the sales tax due, and the total amount due on three separate lines.
1_ Write a program that reads a character and prints it only if it is 'y' or 'Y' (Simulation of If-Else then structure). 2_Write a program that prints the odd numbers between 1 and 10 using loop (Number 1 ASCII code is 49).
Homework write a program that will add the terms of an infinite geometric series. The program should read the first term (a) and the common ratio (r) for the series. It should the compute the sum in two ways: by formula (s=a/1-r), and by adding the individual terms until the answer agrees with the formula to 7 significant digits. The print the formula answer, the answer found by adding terms, and the number of terms that were added. Print the sums to at least ten places. Verify input with a while loop. Two real values are equal to n significant digits if the following condition is true: |a-b|<|a*10^-n| Wrong test - this won't work if r is very near one. Try a=2, r=.99999 With smaller values of r, it is asking for too much precision. With a=2,r=.99, it is getting 10 significant digits. HELP ME FIX CODE.

Write a program that displays every integer between 1 and 100 that is divisible by 5 or 7, but not both. Write it using While and for.
2. a) Correct the code to print the following: 0 1 2 3 4 5 6 7 8 9 b) then rewrite the code with using the while loop. int[] numbers = new int[10]; for(int i=0; i < numbers.length; ++i) numbers[i] = i * 3; for(int i=0; i < numbers.length; ++i) System.out.print(numbers[i] / 2 + 1 + " "); System.out.println();
When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. The input begins with an integer indicating the number of integers that follow. Ex: If the input is: 5 30 50 10 70 65 the output is: 20 40 0 60 55 The 5 indicates that there are five values in the list, namely 30, 50, 10, 70, and 65. 10 is the smallest value in the list, so is subtracted from each value in the list. For coding simplicity, follow every output value by a space, including the last one. 272772.1571588
A word is called as a good word if all the letters of the word are distinct. That is, all the letters of the word are different from each other letter. Else, the word is called as a bad word. This can be continued based on the user input is 'Y'.
Write a program that performs arithmetic division. The program will use two integers, a and b (obtained by the user) and will perform the division a/b, store the result in another integer c and show the result of the division using cout. In a similar way, extend the program to add, subtract, multiply, do modulo and power using integers a and b. Modify your program so that when it starts, it asks the user which type of calculation it should do, then asks for the 2 integers, then runs the user selected calculation and outputs the result in a user friendly formatted manner.
