Example-
array is {4,5,3,2,8}
Sum of all element is 22
program:
#include < iostream>
using namespace std;
class r4r
{
public:
int sum(int *a, int n)
{
int i,sum=0;
for(i=0;i< n;i++)
sum=sum+a[i];
cout<<"Sum of array is: "<< sum;
}
};
int main()
{
int arr[10],i;
cout<<"Enter 5 element in array"<< endl;
for(i=0;i< 5;i++){
cin>>arr[i];
}
//create class object
r4r obj;
obj.sum(arr,5);
return 0;
}
Enter 5 element in array
1 2 3 4 5
Sum of array is: 15
