C Pseudocode

[philmetz]

Hi, below i created some Pseudocode for a program i am writing in C. Could some please have a look at it and provide feedback whether the loop will work? Thanks

CHARACTER name [1..20]
INTEGER iso  0
CHARACTER aperture  0
CHARACTER menuNo  0
FLOAT exposureTime  0

Output ‘Exposure Time Calculator’

Repeat
	Output ‘MENU............................................’
	Input  menuNo

	If menuNo = 1 then
		Output ‘Please enter your name’, name
		Input name
	Else if menuNo =2 then
		Output ‘Please enter the ISO number’, iso
		Input iso
If iso != 6 || iso != 8 || iso != 10 || iso != 12 || iso != 16 || iso != 20 || iso != 25 || iso != 32 || iso != 40 || iso != 50 || iso != 64 || iso != 80 || iso != 100 || iso != 125 || iso != 160 || iso != 200 || iso != 250 || iso != 320 || iso != 400 || iso != 500 || iso != 640 || iso != 800 || iso != 1000 || iso != 1250 || iso !=1600 || iso != 2000 || iso != 2500 || iso != 3200 || iso != 4000 || iso != 5000 || iso != 6400 the
	Output ‘Error in ISO value’
	Iso  0
		
	Else if menuNo = 3 then
		Output ‘Please enter your aperture value’, aperture
		Input aperture
If aperture != f1.2 || aperture != f1.4 || aperture != f1.8 || aperture != f2 || aperture != f2.8 || aperture != f4 || aperture != f5.6 || aperture != f8 || aperture != f11 || aperture != f16 || aperture != f22 || aperture != f1.432 then
	Output ‘Error in aperture value’
	Aperture  0	
	
	Else if menuNo = ? then
		Output ‘welcome to the help menu’
	Else if menuNo = Q then
		Program ends
	Endif
Until iso != 0 and aperture != 0

So basically i want to be able to input in menu number at any time and once it has a value for iso and aperture it ends.

should work
aperture should be a char array or a float
iso needs to be put through a string to int converter

[philmetz]

aperture yes will be a char array.
but why should iso be put through the converter? its a int value??

[philmetz]

my if statement in aperture and ISO.
i dont need an else for that right? if i dont need one i dont need to put one?
thanks
