Read the instructions for your favourite dish. Write a program to display the recipe on the screen but with a difference. The quantity of each ingredient must be multiplied by a value entered from the keyboard. For example, if the recipe needs 2 cups of flour the output displayed will be something like this Please enter the factor to multiply the ingredients with : 4 Recipe name Ingredients // other ingredients 8 cups flour Method The program has the following structure: • Declare an int variable named mFactor to store the value with which the quantity of each ingredient must be multiplied. • The program must make use of a cin statement to input a value from the keyboard and store it in mFactor. Submit both your program and output. COS1511/103/0/2022 3 Question A teacher at Leva Primary School needs to divide her class in different group sizes according to the activity they have to do. This will help her to prepare workstations for each group. For example, for art projects the class has to be divided in groups of 6; for science projects the class has to be divided in groups of 4. She asked you to write a program to determine the number of groups as well as the number of pupils who are left to form a smaller group. There are 56 pupils in the class. The program has the following structure: • Declare three int variables nrPupils, nrGroups, and nrLeft. nrPupils represents the number of pupils in a class, nrGroups represents the number of groups the class is divided into, and nrLeft represents the number of pupils, if any, who are in the remaining smaller group. • Assign the value 56 to nrPupils. • Declare an int variable groupSize that is used by a cin statement to input a value from the keyboard and store the size of the groups the teacher requested. Display an appropriate message. E.g. Please enter the size of each group? • Write the statement to calculate the number of groups of size groupSize. • Write the statement to calculate the number of pupils who are in the remaining smaller group. The output of the program must be displayed as follows: There are 9 groups consisting of 6 pupils There are 3 remaining pupils Submit both your program and output Question 3 . You are requested to write a very simple calculator. Your calculator should be able to handle the five basic mathematic operations – add, subtract, multiply, divide and modulus – on two input values. Your program should have the following structure: • Ask the user to enter two float variables named var1 and var2 • Ask the user to enter a character variable named operation to represent the operation to be performed on the two variables. • Perform the appropriate operation by using if-statements • The output must be given in fixed-point notation with two digits after the decimal point. A typical run is displayed below: Please enter the first float value: 35.6 Please enter the second value: 24.12 Please enter the operation required : + The sum of 35.6 and 24.12 is 59.72 Submit both your program and output.
