2. Simple 12 Hour-Time Arithmetic. The program would accept the current time from a user (in hours and minute) and also accept the number of hours or minutes to add to the current time. The program should then output the result of the computation in hours and minutes using 12 hour format. Please enter current time (Hour): 12 Please enter current time (minutes): 05 Enter hour(s) to add: 3 Enter minute(s) to add: 55 OUTPUT = 4:00 %3D

Write a program that performs as a very simple calculator. Your calculator should be able to handle the four basic math operations — add, subtract, multiply, and divide — on two input values. Your program should prompt the user to enter three arguments: two double values and a character to represent an operation. If the entry arguments are 35.6, 24.1, and '+', the program output should be The sum of 35.6 and 24.1 is 59.7.
When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('{:.2f}'.format(your_value)) Ex: If the input is: 5 30.0 50.0 10.0 100.0 65.0 the output is: 0.30 0.50 0.10 1.00 0.65 python

Write a program that first reads the value n, which is the number of numbers to average. It should then read the n positive (float) numbers, average them, and display the average. ENTRYAn integer n and then the n floating numbers EXIT The average of the n numbers read. Example of program execution: Input 3 Entry 2.5 Entry 3.8 Entry 4.6 Output3.633333333333333
WRITE A PROGRAM TO CALCULATRE THE AREA OF A RECTANGLE OF LENGTH =5 CM AND BREADTH=8CM. CALCULATE THE PRICE OF AN ITEM COSTING 100 GHANA CEDIS AFTER A DISCOUNT OF 10% IS APPLIED TO IT. WRITE A PROGRAM TO CALCULATE THE SIMPLE INTEREST ON A LOAN AMONUT OF 50000 GHANA CEDIS AT AN INTEREST RATE OF 30% FOR A NUMBER OF YEARS WHICH WILL BE SPECIFIED BY THE USER. WRITE A PROGRAM TO CALCULAT THE AGE OF THE USER AFTER THE USER ENTERS HIS OR HER YEAR OF BIRTH.
In Python Write a program that computes the fuel efficiency for a multi-leg journey. The program will first prompt for the starting odometer reading and then get information about a series of legs. For each leg, the user enters the current odometer reading and the amount of gas used (separated by a space). The user signals the end of the trip with a blank line. The program should print the miles per gallon achieved on each leg and the total MPG for the trip
In 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 27
a.Write a python program that asks the user to enter two integer numbers and then perform addition,subtraction, multiplication, and division using these 2 numbers. Then display (print) the results. b. Write a python program that displays converts the binary numbers 100 and 110 to decimal anddisplay them. Then add the two numbers and display the result in decimal, binary, octal, andhexadecimal.
Write a program that computes the molecular weight of a carbohydrate (ingrams per mole) based on the number of hydrogen, carbon, and oxygenatoms in the molecule. The program should prompt the user to enter thenumber of hydrogen atoms, the number of carbon atoms, and the numberof oxygen atoms. The program then prints the total combined molecularweight of all the atoms based on these individual atom weights:Atom Weight(grams I mole)H 1.00794c 12.01070 15.9994For example, the molecular weight of water (H20) is: 2(1.00794) +15.9994 = 18.01528.
Two number systems, octal (base 8) and hexadecimal (base 16), are of interest to computer scientists. In fact, in C++, you can instruct the computer to store a number in octal or hexadecimal. The digits in the octal number system are 0,1,2,3,4,5,6, and 7. The digits in hexadecimal number systems are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E, and F. So A in hexadecimal is 10 in decimal, B is 11 in decimal, and so on. The algorithm to convert a positive decimal number into an equivalent number in an octal (or hexadecimal) is the same for binary numbers. Here, we divide the decimal number by 8(for octal) and by 16(for hexadecimal). Suppose ab represents the number a to the base b. For example, 7510 means 75 to the base 10(that is decimal), and 8316 means 83 to the base 16(that is hexadecimal). Then 75310 =13618 and 75310= 2F116* Write a program that uses a recursive function to convert a number in decimal to base 8 or base 16.
