An array have ten elements print all even number and their sum in the array

Answer 1

@Svengat: it should with a few corrections. ; () Ram will need to add a sum variable to it as well but yeah this should work fine.

Answer 2

Something like this should do it. (using Svengats answer with corrections)

int sum = 0;
for(int i = 0; i < 10; ++i) {
if(arr[i]%2==0){
cout<<arr[i]<<endl;
sum+=arr[i];
}
}

This should also go along way to answering your two other (homework?) questions.

Answer 3

for (i=0;i<10;i++){if arr[i]%2==0{cout<<arr[i]<<endl}}
