🔒 Closed Java Calculator: Badly Need idea or code for my calculation

[PHC-DarkJaVa]

Good day po sa mga programmer!

Badly need ng help para sa calculation ng code ko. ang process nya dapat ma calculate ko ung naka contain sa array by using any operator. ung addition nag wowork using for loop pero other operator hindi na. since si user ung mag ccreate ng length/size para sa array ko. Nahihirapan ako icode manually create variable to store the data since si user mismo ung mag lalagay kung ilang number ba icocompute nya.

ito ung code ko for loop gamit ko sa addition:

for(int i = 0; i < myArr.length; i++){
                    total = total + myArr[i];
                }
            
                System.out.print("The result of ");
                for(int i = 0; i < size; i++){
                    if (i > 0){
                        System.out.print(" + ");
                    }
                    System.out.print(myArr[i]);
                }
                readInput(total);

sana may makatulong ASAP badly need ko sya

Salamat sa inyo!

gamit ka switch case or else if, i prefer switch

ok na po ako sa swichcase ung problem ko lang po papano ko icacalculate ung single array kasi pag forloop sa addition nagana pero pag minus hindi nagana laging add lang

change the operator po, yung code is addition, how to make it into a subtraction? change operator symbol

ginawa ko po sya like

total-=myArr[i]

pero nagiging negative sya pero nag a-add padin ung sila kaya medj nahirapan ako

gawin ko to later. tapusin ko muna statistics ko.

Base sa code mo; yung total is for sum. So, need mo pa ulit gumawa ng panibagong variable for other operations. Palitan mo na lang si total ng "sum" para di ka maguluhan. Bale ganito mangyayari:

for(int i = 0; i < myArr.length; i++){
                    sum += myArr[i];
                    difference -= myArr[i];
                    product *= myArr[i];
                    qoutient /= myArr[i];
                }
            
                System.out.print("The sum of ");
                for(int i = 0; i < size; i++){
                    if (i > 0){
                        System.out.print(" + ");
                    }
                    System.out.print(myArr[i]);
                }
                readInput(Sum);

execution will be wrong, values is different from expected output

Same lang yan. Need niya lang naman ilagay sa loob ng if else, kung anong pinili na operator ni user.

nope, values will be different if you try to execute it.

Paano naging different? Di ko masyado magets HAHAHAHA. Sabi niya lang kasi,

ang process nya dapat ma calculate ko ung naka contain sa array by using any operator.

execute the code po and you will see.

ganito lang yan, no operator choice pero mdas execution.

import java.util.*;

class Test {
   public static void main(String[] args) {
      Scanner in = new Scanner(System.in);
      int[] arr;
     
      System.out.print("Enter how many numbers to calculate: ");
      int num = in.nextInt();
      arr = new int[num];
      for(int i = 0; i < arr.length; i++) {
         System.out.print("Enter a number: ");
         arr[i] = in.nextInt();
      }

//parts of the code are intentionally excluded

Enter how many numbers to calculate: 2
Enter a number: 100
Enter a number: 5
SUM: 105
DIFFERENCE: 95
PRODUCT: 500
QUOTIENT: 20

whoa kung sakaling may execution po operator may way po ba dun? since yun ung required sakin e, kung pwedeng ganto lang gawin ko ays.

yes pwede what type of operation should be used depende sa choices na gusto mo. add lang ng additional lines of codes .

tip: dont sort, difference not only involves positive integers, may negative integers din

set 1st position of array as the 1st input.

ok lang. mas mas mabuti may mali kasi diyan talaga nagsisimula lahat.
