are odd.
a. Read in one number at a time.
b. Compute and display the number of even integers and the number of odd integers.
Hint: You can use the modulus operator (%) to determine if each integer is even or od.
Your output should look like this:
Enter integer: 2

Write a program that uses a random number generator to generate a two digit positive integer and allows the user to perform one or more of the following operations:
Double the number.
Reverse the digits of the number.
Raise the number to the power of 2, 3, or 4.
Sum the digits of the number.
If the number is a two digit number, then raise the first digit to the power of the second digit.
If the number is a three digit number and the last digit is less than or equal to 4, then raise the first two digits to the power of the last digit.
After performing an operation if the number is less than 10, add 10 to the number. Also, after each operation, determine if the number is prime. Each successive operation should be performed on the number generated by the last operation. Your program should not contain any global variables and each of these operations must be implemented by a separate function. Also,
your program should be menu driven.

A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…arrow_forwardSummary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Find the smallest value, and then subtract it from all three values, thus removing the gray.arrow_forward

- Write a program that calculates the equivalent resistance of a circuit. n electrical resistors with resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied across each. Their equivalent resistance Reg is related to the values R1, R2, ..., Rn by: 1 1 1 1 + +...+ R R R, R. "eq Write a program that prompts the user to enter the resistance of n resistors. The user should be prompted continuously by using a while loop until a zero or negative value is entered (the program should count the number of resistors n entered by the user and store the values in an array). Use another separate loop to print the resistance values entered by the user and the equivalent resistance Reg.

For example, (2, 2) is inside the rectangle and (6, 4) is outside the rectangle, as shown in the Figure. (Hint: A point is in the rectangle if its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its vertical distance to (0, 0) is less than or equal to 5 / 2.) Here are sample runs of the program: Sample 1: Enter a point with two coordinates: 2 2 Point (2.0, 2.0) is in the rectangle Sample 2: Enter a point with two coordinates: 6 4 Point (6.0, 4.0) is not in the rectangle Analysis: (Describe the problem including input and output in your own words.)
