#include <iostream>
#include <cmath>
int main()
{
    char op;
    int num1;
    int num2;
    int result;

    std::cout << "Enter operator:";
    std::cin >> op;

    std::cout << "Enter num1:";
    std::cin >> num1;

    std::cout << "Enter num2:";
    std::cin << num2;

    switch(op){
        case "+":
            result = num1 + num2;
        case "-":
            result = num1 - num2;
        case "*":
            result = num1 * num2;
        case "/":
            result = num1 / num2;
    }
    std::cout << result;
    return 0;
}

here's the code

the errors has lots of lines that i cant capture all of them in a pic

std::cin >> num1;

std::cin << num2;

oh sh

my bad srry

i cant remember the >> and <<

[humble flax]

It happens 😄

Why does a beginner need to see all that crap because they mixed up << and >>?

[brave robin]

i always mistaken cin and cout

[humble flax]

cout << x - x is printed TO cout
cin >> x - x is read FROM cin to x

[brave robin]

woww

that helps

tysm

Maybe I'm just used to it, but the error is decent. If you don't read beyond the first section, that is

[brave robin]

uhh

after fixing that

i still got some bugs ;-;

[humble flax]

Show the errors

Yeah, I'm used to it too. But it's super strange imo, and probably goes on for several termpages.

case '+'

[brave robin]

wha

why

[humble flax]

"+" is a string, possibly with multiple or 0 characters. '+' is a single character

Also switch is dumb and can only switch on integers (which includes single characters)

And also you need break; at the end of each case branch

[brave robin]

ohh makes sense

[brave robin]

thanks for the help

!solved
