Question

Using labview from national instruments

ator that can do the following: addition, subtraction, multiplication, division, (8) Design a calcul square, square root, sinO, coso. T to display results of the operation performed. he front panel should have controls for inputs and an indicator

Answer 1

Pseudocode:

program calculator

while(True) #main loop
{ #get choice until input="Q"

#print main menu
print("Welcome to the Calculation Program")
print("(1) Addition")
print("(2) Subtraction")
print("(3) Multiplication")
print("(4) Division")
print("(Q) Quit Program")
#finish print main menu

input=getinput from user (1,2,3,4,Q) #ask the user to input a choice and set input as the choice.

if input=="Q", then print("End Calculator"), break #if input is "Q", then exit main loop

if input==1 #Addition
{
while(True) #addition loop until user ends
{
print("Adds two numbers. Enter "Q" to quit") #print directions
x=getinput from user (first number) #Takes user's first input and stores in x
y=getinput from user (second number) #Takes user's second input and stores in y
if (x=="Q" or y=="Q") then break #if Q, exit addition
print(x+y) #print the answer
}
}

if input==2 #Subtraction
{
while(True) #subtraction loop until user ends
{
print("Subtracts two numbers. Enter "Q" to quit") #print directions
x=getinput from user (first number) #Takes user's first input and stores in x
y=getinput from user (second number) #Takes user's second input and stores in y
if (x=="Q" or y=="Q") then break #if Q, exit subtraction
print(x-y) #print the answer
}
}

if input==3 #Multiplication
{
while(True) #multiplication loop until user ends
{
print("Multiplies two numbers. Enter "Q" to quit") #print directions
x=getinput from user (first number) #Takes user's first input and stores in x
y=getinput from user (second number) #Takes user's second input and stores in y
if (x=="Q" or y=="Q") then break #if Q, exit multiplication
print(x*y) #print the answer
}
}

if input==2 #Division
{
while(True) #division loop until user ends
{
print("Divides two numbers. Enter "Q" to quit") #print directions
x=getinput from user (first number) #Takes user's first input and stores in x
while(True) #Loop to check for 0 denominator
{
y=getinput from user (second number) #Takes user's second input and stores in y
if (y is not 0) then break #if y is ok, then stop input y loop
print("Please enter a non-zero denominator") #send error message and get input again with loop
}
if (x=="Q" or y=="Q") then break #if Q, exit division
print(x/y) #print the answer
}
}
#Restart main loop and reprints main menu, etc.
}
