How to **find** the **sum** of the **elements** of an **array**.

- create an empty variable. (
**sum**) - Initiate it with 0 in a loop.
- Iterate over each element (or get each element from the user), add each element to
**sum**. - Print
**sum**.

In this context, how do you **find** the **sum** of the **elements** in an **array**?

To **find** the **sum** of all **elements**, iterate Go through each element and add the current element to the total. Which will loop from 0 to n. The loop structure should look like this: for(i=0; i**sum** i.e. **sum** = **sum** + arr[i] or you can even do **sum** += arr[i].

Same as add **elements** to add an **array** in java for loops? Getting the **sum** with a for loop implies that you:

- Create an
**array**of numbers, int values in the example. - Create a for statement with an int Variables from 0 up to the length of the
**array**, incremented by one each time in the loop. - In the for statement, add each element of the
**array**to an int**sum**.

In this context, how do you **find** the **sum** in **Java**?

Finding the **sum** of two numbers means simply adding the two numbers together.

- Create a separate variable to store the value of the
**sum**. This can be of type int. - The formula to
**find**the**sum**is: Sum = First number + Second number. - To get these parameters (inputs) from the user, try it with the scanner function in
**Java**.

How do you **find** the **sum** of an **array** in C++?

The basic method to get the **sum** of all Finding **elements** of the **array** consists of iterating over the **elements** of the **array** and adding the element’s value to the **sum** variable.

## What is the syntax of the Do While loop?

Syntax. make { statement(s); } while( condition ); Note that the conditional expression appears at the end of the loop, so the statement(s) in the loop are executed once before the condition is tested. If the condition is true, the control flow jumps back to do and the statement(s) in the loop are executed again.

## How to find the sum in C++?

C++ program for displaying the **sum** of the digits of a specific number

- * C++ program for displaying the
**sum**of the digits of a specific number. - #include
- using namespace std;
- int val, num,
**sum**= 0; - cout<<"Enter the number: ";
- cin>>val;
- num = val;
- while (num != 0)

## How to find the sum of the digits?

The digit **sum** of a number, say 152, is simply the **sum** of the digits, 1+5+2=8. If the **sum** of the digits is greater than nine, the process is repeated. For example, the **sum** of the digits for 786 is 7+8+6=21 and the **sum** of the digits for 21 is 3, so the **sum** of the digits for 786 is 3.

## How to divide in Java? ?

// Divide literal by literal; result is 5 int result = 10 / 2; // divide a variable by another variable; Result is 3 int a = 15; int b = 5; int result = a / b; When dividing integer types, the result is an integer type (see the previous chapter for the exact data type conversions for math operations).

## How do I print an array?

In order Um to print an integer **array**, you just need to call arrays. toString(**int array**) method and pass your integer **array** to it. This method takes care of the contents of your integer **array** as shown below. If you pass **int array** directly to System.

## What is an array in C?

C – Arrays. Advertisement. Arrays are a type of data structure that can store a fixed-size, sequential collection of **elements** of the same type. An **array** is used to store a collection of data, but it’s often more useful to think of an **array** as a collection of variables of the same type.

## What is an array?

An arrangement of objects, images or numbers in columns and rows is called an **array**. Arrays are useful representations of multiplication concepts. This **array** has 4 rows and 3 columns. It can also be described as a 4 by 3 **array**. Arranging equal groups in equal rows forms an **array**.

## What is a Java Loop?

The **Java** For Loop is a control flow statement that is part of the programs iterates several times. The **Java** while loop is a control flow statement that repeatedly executes a part of the program based on a given Boolean condition.

## How to find the sum of an array in Java?

Algorithm

- STEP 1: START.
- STEP 2: INITIALIZE arr = {1, 2, 3, 4, 5}
- STEP 3: SET
**sum**= 0. - STEP 4: REPEAT STEP 5 UNTIL i
- STEP 5:
**sum**=**sum**+ arr[i] - STEP 6: PRINT “
**sum**of all**elements**of a Arrays:” - STEP 7: PRINT
**sum**. - STEP 8: END.

## How do you find the sum?

To **find** the **sum** of an arithmetic progression, start by identifying the first and last numbers in the sequence. Then add those numbers together and divide the **sum** by 2. Finally, multiply that number by the total number of terms in the sequence to **find** the **sum**.

## How do you add an element to an array?

Just add the required item in the list using the add() method. By creating a new **array**:

- Create a new
**array**of size n+1, where n is the size of the original**array**. - Insert the n
**elements**of the original**array**into this**array**. - Add the new element at position n+1.
- Print the new
**array**.

## What is array example?

An **array** is a variable that can store multiple values. For example, if you want to store 100 integers, you can create an **array** for them. int data[100];
