I am stuck up with a question on appending of two arrays I am writing the code for the same, I am appending two strings this way int main() { string s1 = "Welcome to C++"; string s2 = "C++ improves the logic ability"; string s3 = s1 + s2; cout<<s3<<endl; } But if I go ahead with the integer datatype , it doesnt work int main() { int arr[4] = {2,3,4,5}; int arr1[4] = {6,7,8,9}; int arr3[9] ; arr3 = arr + arr1;//displays error arr3 = arr ++ arr1; // works properly } Can anyone please clear my doubt in this question ?
