Jayakrishna🇮🇳 That's not enough...
He also has to specify array size ,otherwise the Sum doesn't give the expected output..

Now it is still causing problem
Can u send me the correct code

Answer 10

#include<iostream>
using namespace std;
int sum=0,x;
int main()
{
int arr[]={1,3,5,9,5,7,0,8};

//you are missing braces for loop, if you dont provide then only next 1 statement comes into a loop, so sum+=arr[x] will not part of loop.
for(int x=0;x<8;x++)
{
cout<<"print number "<<arr[x]<<endl;
sum+=arr[x];
}

cout<<"\nsum = "<<sum<<endl;
return 0;
}

Edit :
for finding array size in c/c++, you can use this formulae :
int size= sizeof(arr)/sizeof(arr[0]);
So now instead of use size as x<size;

Answer 11

Alphin K Sajan anas kayani for finding array size in c/c++, you can use this formulae :
int size= sizeof(arr)/sizeof(arr[0]);

Answer 12

Yes
