How to find the sum of elements of an array in Scala
Theodore Kelechukwu OnyejiakuOverview
We use the while loop to obtain the sum of elements of an array in Scala. The logic is to create an initial sum variable which will be zero. Then in the loop, we will increase this sum with each array element.
Syntax
while(condition){
// loop body
}Syntax for a while loop
Parameters
condition: This is a conditional statement. If it returns true, the code body will execute. Otherwise, the code body will not execute.
Example
object Sample {
def main(args: Array[String]) {
// create an array
var OurArray = Array(10,20,30,40,50)
// create a counter
var counter = 0;
// create default sum
var sum = 0;
// create a while loop
while(counter<OurArray.size) // check if counter is less than array size
{
// add element value to sum
sum = sum + OurArray(counter)
counter = counter + 1
}
// print sum of array elements
printf("Sum of array elements is: %d\n",sum)
}
} The syntax for getting the sum of elements of an array
Explanation
- Create an array and two integer variables to hold the
sumandcounterfor every loop.
- Then add the value of array elements to the variable, after accessing and adding all elements to the variable
sum. Print the value of the variable on the console screen.
