Answer to Question #301764 in Algorithms for ggfh

Question

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.

Answer 1

Start add(a,b):
  return a+b 
Stop
Start sub(a,b):
  return a-b
Stop
Start mult(a,b):
  return a*b
Stop
Start div(a,b):
  return a/b
Stop
Start main:
	Declare integer ch=-1
	Declare float number1
	Declare float number2
	Declare float sum
	Declare float difference
	Declare float product
	Declare float d
	while ch<>5:
		Display "MENU OF OPERATIONS"
		Display "[ 1 ] - Addition"
		Display "[ 2 ] - Subtraction"
		Display "[ 3 ] - Multiplication"
		Display "[ 4 ] - Division"
