Write the definition of a method named sumArray that has one parameter, an array of ints. The method returns the sum of the elements of the array as an int.

Answer 1

Answer:  Following code is in C++

#include<iostream>

using namespace std;

int sumArray(int a[])  //take array as argument

{

   int s=0,i;

   for(i=0;i<5;i++)

       s+=a[i];  //sums every element

   return s;

}

int main() {

   int sum,a[]={1,7,4,9,6};

   sum=sumArray(a);   //calling the function

   cout<<"Sum of array is : "<<sum;   //printing sum to console

return 0;

}

OUTPUT :

Sum of array is : 27

Explanation:

In the above mentioned code, an array is declared and initialized at the same time. A variable sum of int type stores sum returned the function sumArray() and then it is printed to the console. In the function sumArray(), a variable s of data type int is initialized with value 0 and a loop is executed in which every element of the array is added. At last, s is returned.
