Sum of all Array elements means add all array Elements. Suppose we have 4 Elements in array and we want to find there sum.
arr[0]=4
arr[1]=2
arr[2]=1
arr[3]=6
Sum off all above elements are
arr[0]+arr[1]+arr[2]+arr[3]=4+2+1+6=13
arr[0]=4
arr[1]=2
arr[2]=1
arr[3]=6
Sum off all above elements are
arr[0]+arr[1]+arr[2]+arr[3]=4+2+1+6=13
C++ program to Find Sum of an Array Elements
#include<iostream.h> #include<conio.h> void main() { int arr[20],i,n,sum=0; clrscr(); cout<<"How many elements you want to enter: "; cin>>n; cout<<"Enter any "<<n<<" elements in Array: "; for(i=0;i<n;i++) { cin>>arr[i]; } cout<<"Sum of all Elements are: "; for(i=0;i<n;i++) { sum=sum+arr[i]; } for(i=0;i<n;i++) { } cout<<sum; getch(); }
Output
How many elements you want to enter : 5 Enter any 5 elements in Array: 1 4 2 7 5 Sum of all Elements are: 19
