Display output text times a variable



Hello i need some help on what to add to the following if statement for the out put to read the value of sum times the actual number of sum:



```
public class ICMA42
{
   /* instance variables */
   private int alpha;
   private int bravo;
   private int sum;

   /**
    * Constructor for objects of class sum which initialises sum to 0.
    */
   public ICMA42()
   {
      this.alpha = 0;
      this.bravo = 0;
   }

   /**
    * Sets the value of alpha to the receiver to the value of the argument aAlpha.
    */
   public void setAlpha (int aAlpha)
   {
      this.alpha = aAlpha;
      this.sum = alpha + bravo;
   }

   /**
    * Sets the value of alpha to the receiver to the value of the argument aAlpha.
    */
   public void setBravo (int aBravo)
   {
      this.bravo = aBravo;
      this.sum = alpha + bravo;
   }

   /**
    * find the sum of the two int type arguments and store the result in a local variable called sum 
    */
   public void sumArgs()
   {
     if (sum > 10)
     {
      System.out.println("Sum is " + this.sum);
     }
     if ((sum >= 1) && (sum <= 10))
     {
      System.out.println("Sum is " + this.sum);
     }
   }
}

```
I am confused, do you have 2 variables called sum? One decleared globally and one that is a parameter of a method? Maybe show the entire code or give more explanation
for this, just use an if function. see https://macmost.com/learn-how-to-use-the-if-function-in-numbers.html so something like this in a2: if(isblank(b2),c2,b2) the condition is to check if b2 is blank. if it is, get the value of c2. if it isn’t blank, then get the value of b2. method a.increment() overlaps in class b.   
 therefore, regardless of the type of the variable obj, will be called the method corresponding to the actual type of the object - that is, b.increment().  
 
this method will use the variable i, declared in the same class b and having an initial value of 10.  
 
the resulting value - 11. if statements always check if an expression evaluates to the value of true. since you’re checking whether the value true  value true then it’ll run every time. as for the “purpose” of the if statement, it’s here to create a “block scope” within the “function scope”.

interestingly, if you remove … The problem is that your pair's closure must return two different types of objects: int if you ask for "con", and the next closure on the line if you ask for "crd".


Here's one possible implementation:


Use a speaker so you can come back.



```
public static Func<string, dynamic> Pair(int x, Func<string, dynamic> y)
{
    Func<string, dynamic> pair =
           (a) =>
           {
               if (a == "con") return x;
               if (a == "crd") return y;
               throw new Exception();
           };

    return pair;
}

public static void Print(Func<string, dynamic> pair)
{
    while (true)
    {
        var next = pair("crd");
        Console.WriteLine((next == null ? "-":"+") +"> " + pair("con"));
        if (next != null)
        {
            Console.WriteLine("|");
            pair = (x) => next(x);
            continue;
        }
        break;
    }
}

        

        
        
        
 (adsbygoogle = window.adsbygoogle || []).push({});
 
        

    
```


  




 (adsbygoogle = window.adsbygoogle || []).push({});
 
  

Test:



```
var pair = Pair(1,
            Pair(2,
                  Pair(3,
                        Pair(4, null))));

Print(pair);

        

        
        
        
 (adsbygoogle = window.adsbygoogle || []).push({});
 
        

    
```

output:



```
+> 1
|
+> 2
|
+> 3
|
-> 4

        

        
        
        
 (adsbygoogle = window.adsbygoogle || []).push({});
 
        

    
``` you can simply write (i.e. do not expand the variable):

if (my\_var strequal "true")

in this case, a non-existing variable will evaluate to false (boolean value as defined by cmake).

and, in the case of expected value is a true value as defined by cmake:

if (my\_var) c = input()  

t = len(c)  

temp = ""  

for i in range(0,len(c)):  

    if t<3:  

        break  

    else:  

        if i in (0,1,t-2,t-1):  

            temp = temp+c[i]  

        else:  

            continue  

print(temp) void alpha\_0\_beta\_and\_c01(){

// groot->setstyle("plain");

gstyle->setoptfit(1111);

auto c1= new tcanvas("c","bpre",10,10,600,600);

c1->divide(1,1);

c1->settickx();

c1->setticky();

c1->settitle("");

c1->setlinewidth(3);

c1->setbottommargin(0.1);

c1->settopmargin(0.05)… Here's an example of one possibility. Just season to taste... 



```
extends Node2D
var x_delta = 0

func _physics_process(delta):
    var input_velocity = Vector2.ZERO

    if Input.is_action_just_pressed("ui_right"):
        x_delta = 1

    if Input.is_action_just_pressed("ui_left"):
        x_delta = -1

    if Input.is_action_just_released("ui_right") && x_delta > 0:
        x_delta = 0

    if Input.is_action_just_released("ui_left") && x_delta < 0:
        x_delta = 0

    input_velocity.x = x_delta

    print(input_velocity.x)
