✅ Calculator Help

Basically im making a calculator with 9 number buttons. How do i make it so that when 2 number buttons that are pressed in a row, ex. 1 and 1. Display and calculate as 11 as in eleven and not (1 + 1) as in 2

thx lmk if u need all the code so far

Simple. When you click numeric buttons, append that number to some variable. Perform calculations only when you press the math buttons

The exact way actual calculators work

Yes but so. If only numeric button 1 is pressed then the variable would have 1 in it. If its pressed again wouldn't the variable now have 2 inside? not 11? Help idk sorry

Oh wait uhhh

Mmm

You can use a list to store those numbers, and then calculate the actual number from that

Or use a string and later parse it

Basically what i was gonna do is store the 2 different numbers that the user wants to calculate, store tje result as an int, and then display the result in the form of a label using result.ToString();

but other than that

iii think i understand ill come back if it anything doesnt work out correctly

Alrighttt that works but how do i get the second number input after an operator button is clicked?

How about storing your current value before you clear the input?

i did label1.Text = num1.ToString();

Just to display

the number

as a string

but id need to convert it back to int if i do calculations with it

int.Parse() and int.TryParse() would like to introduce themselves

Did that

right after

got an error for some reason

public void button1_Click(object sender EventArgs) {
num1 = Int.Parse(num1.ToString() + "1");
label1.Text = num1.ToString();
num1 = Int.Parse();
}

no clue what im doing wrong

judging by that it's clear that you lack the fundamentals. I suggest studying those before jumping into a gui framework

Ehhhh i did some gui work on java so its fine

basically the same syntax

you clearly don't understand how methods and parameters work

what this line supposed to do ?

convert from string back to int to be able to do operations on it with num2

also gui frameworks are best used with bindings and reactivity, which is an abstraction that's hard to understand for beginners who lack basics, but it's the most efficient way to program guis

num1 is already an int

when you type "num1.ToString()" it doesn't change its type

o wait help im dumb

Did you solve @rei ?

yea all good

ty

Type "/close" then 👍
