Write a program using pseudocode to create four functions add(a,b) to add a and b then return the result, similarly sub(a,b), mult(a,b), div(a,b) to perform mathematical operations. Provide a menu to choose which calculation to perform. Parameters a and b are inputs from user.

Given two numbers X and Y, create a program that determines the difference between X and Y using if-else. If X - Y is negative, compute R = X + Y; if X - Y is zero, compute R = 2X + 2Y; and if X - Y is positive, compute R = X * Y. Print the values of X, Y, and R.

The population of a town A is less than the population of town B.However, the population of

algorithmoutputs after how many years the population of town A will be greater than or equal to

flowchartthat prompts the user to enter the population and growth rate of each town. The

Population of town A =5000, growth rate of town A = 4%, populationof town B = 8000, and

town A is growing faster than the population of town B. Write algorithm usingpseudocodeand

the population of town B and the populations of both the towns at that time. (A sample input is:

growth rate of town B =2%)

Write algorithm using pseudocode and flowchart that uses while loops to perform the

following steps:

i. Prompt the user to input two integers: firstNum and secondNum note that firstNum

must be less than secondNum.

ii. Output all odd numbers between firstNum and secondNum.

iii. Output the sum of all even numbers between firstNum and secondNum.

iv. Output the numbers and their squares between firstNum and secondNum.

v. Output the sum of the square of the odd numbers between firstNum and secondNum.

b. Redo Exercise (a) using for loops.

c. Redo Exercise (a) using do. . .while loops.
