[limpid needle]

hy everyone
i have here an exercises:
ask me to initialize 4 int variable, the first 3 variables cout with the user imput cin ; the 4th=2th; (imput real numbers ex: 0, 1, 2, 3..)
the exercise ask me to sort the first 3 int entered values ​​in ascending order.

What do you want to achiebe exactly? Its hard to understand.

[limpid needle]

want to sort my variables in ascending order

have 3 variable in imput user (real numberses 47, 89, 93)

the forth int variable = 89;

[dapper storm]

do you know how to use for() loop yet

[limpid needle]

not yet

[dapper storm]

and I don't understand you either

so the 4th must equals to 2th

and you must use only "if else"

am I correct

[limpid needle]

yes

This can be done with three if() statements.

if (b < a)
  swap(a, b);

if (c < a)
  swap(a, c);

if (c < b)
  swap(c, b);

I have no clue what the purpose of your 4th number is.

[limpid needle]

can't swap it

[autumn turret]

#include <iostream>

int main()
{
    int a, b, c;
    a = 3;
    b = 2;
    c = 1;
    int s[3] = {a, b, c};

    if (s[0] > s[1])
    {
        int tmp = s[0];
        s[0] = s[1];
        s[1] = tmp;
    }
    if (s[1] > s[2])
    {
        int tmp = s[1];
        s[1] = s[2];
        s[2] = tmp;
    }
    if (s[0] > s[1])
    {
        int tmp = s[0];
        s[0] = s[1];
        s[1] = tmp;
    }

    std::cout << s[0] << std::endl;
    std::cout << s[1] << std::endl;
    std::cout << s[2] << std::endl;

    return 0;
}

This works

[limpid needle]

must use =

[sage terrace]

So, do it the hard way.

[autumn turret]

The hard and ugly way ^^

[limpid needle]

unisersity exercise 😦

[sage terrace]

I will leave that as an exercise for the reader.

[autumn turret]

@limpid needle is my solution fine?

can you use it or do you need another one? ^^

[limpid needle]

I think it works ... but it doesn't meet the exercise terms

[autumn turret]

why not? because of the array? we can fix that quite easily

And yes it does work. I tested it (with all possible situations).

[limpid needle]

yes ... we haven't talked about arrays yet

[autumn turret]

    if (a > b)
    {
        int tmp = a;
        a = b;
        b = tmp;
    }
    if (b > c)
    {
        int tmp = b;
        b = c;
        c = tmp;
    }
    if (a > b)
    {
        int tmp = a;
        a = b;
        b = tmp;
    }```
then here you go

[limpid needle]

i think this one work's fine.

I'll let you know shortly

thank you for the support

[autumn turret]

alr. no problem ^^

[limpid needle]

i appreciate it

[autumn turret]

If you need help with the next exercises or smth related to C++ you can ask me directly (via discord private messages).. if you want of course ^^

[limpid needle]

I will definitely do it ... you do not know how much I am grateful to hear you say it ... I am a beginner, and the manuals that the university provide us do not give sufficient examples and explanations

[autumn turret]

Where do you study and which language do you speak?

[limpid needle]

i study in genova... italy

but i'm romanian

[autumn turret]

ahh okay
