[C++] calculator using stacks

[ayu]

A very simple calculator made using stacks, that can perform very simple arithmetic operations.

Code: Select all

Example

Type a fully parenthesized arithmetic expression:
(((14*4) + 5) + ((4 * 6) + 10))

That evaluates to 95

hmmm sorry to be a knob but something doesn't look right in the equation above. Is it my eyes or is it just random to give a brief explanation?

Probably me smoked too much

hmm yeah you're right, this would be more accurate.

(((14*4) + 5) + ((4 * 6) + 10))


(((56) + 5) + ((4 * 6) + 10))

(61 + ((4 * 6) + 10))

(61 + (24+ 10))

(61 + 34)

95

Cats bravo.

By the look of the code you thought this through a little carefully. Most calculators let the cpu just compute the arithmetic value such as:

Code: Select all

int i,i2;
cin>>i; //Input first int.
cin>>i2; // Input Second Int.
int add = i+i2; //Results.

Which the code above is only limited to two integers or how many integers the programmer supplied, but your code goes beyond that level. And plus extra karma for using different libraries rather than just cheating and using the <math> library.

Is this one of your Uni assignments btw?

Jupp it's an assignment for tomorrow =)

Nice.

I've seen Uni has greatly improved your programming skills. Which is awesome man.

Good luck.
