Help. Exiting program?

[bigman9]

Hey i just made this program.
i want if so that when you hit 0 it exits the program. can someone help me. thanks:)



var pick: real:=0
var number: real
loop
put "Please enter the number that you wish to expariment with"
get pick

put "Select your choice of calculation:"
put "1) Square of the number"
put "2) Square root of the number"
put "3) Reciprocal of the number"
put "4) Cube of the number"
put "5) Cube root of the number"
put "0) Exit program"
get number

if number = 1 then
put pick*pick
end if

if number = 2 then
put sqrt(pick)
end if

if number = 3 then
put pick/(pick*pick)
end if

if number = 4 then
put pick*pick*pick
end if

if number = 5 then
%put pick^1/3
end if

if number = 0 then
exit
end if
end loop

Enclose the whole program in a conditional loop which will exit if 0 is entered anywhere...

[bigman9]

it didnt work:/

Do you want the program to exit if the first input is 0?

[syntax]
Ask for first number

if number != 0

Display options

else choice = 0

then you if else conditions will automatically exit the program for you.

The second but i think i got it...



var pick: real:=0
var number: real
var chars : array char of boolean
put "Please enter the number that you wish to expariment with"
get pick
loop
put "Select your choice of calculation:"
put "1) Square of the number"
put "2) Square root of the number"
put "3) Reciprocal of the number"
put "4) Cube of the number"
put "5) Cube root of the number"
put "0) Exit program"
get number

if number = 1 then
put pick*pick
end if

if number = 2 then
put sqrt(pick)
end if

if number = 3 then
put pick/(pick*pick)
end if

if number = 4 then
put pick*pick*pick
end if

if number = 5 then
put pick**(1/3)
end if

if chars ('0') then
exit
end if
end loop

Turing:

var pick : real := 0 var number : real var chars : array char of boolean put "Please enter the number that you wish to expariment with" get pick loop     /*only show this menu if if pick is not 0     otherwise, set number to 0*/     put "Select your choice of calculation:"     put "1) Square of the number"     put "2) Square root of the number"     put "3) Reciprocal of the number"     put "4) Cube of the number"     put "5) Cube root of the number"     put "0) Exit program"     get number     if number = 1 then         put pick * pick     end if     if number = 2 then         put sqrt (pick)     end if     if number = 3 then         put pick / (pick * pick)     end if     if number = 4 then         put pick * pick * pick     end if     if number = 5 then         put pick ** (1 / 3)     end if     if chars ('0') then         exit     end if end loop

I want the menu to show so they see the option that 0 is to exit. then when they hit 0 then enter it exits the program?

[bigman9]

but now when i click any other nymber it exits the program

Simply throwing a question mark at the end of a sentence does not necessary turn it a question.

[bigman9]

okaaay...How come when i click numbers 1-4 it closes the program wehn i put if chars ('0') then exit?

[Tony]

Your program comes to the end via some other path.

[bigman9]

can you please hook me with the correct code for the end then?

The logic is alright.
I have forgotten the turing syntax and there is an extra end loop at the end....

I was editing that but then you replied
