The associativity of which of the following operators is Left to Right, in C++ ?

Answer: Array element access ([]) has left-to-right associativity in C++.

Explanation:

• Array element access ([]): left-to-right associativity. Example: in the expression arr[i][j], grouping is (arr[i])[j], so the leftmost subscript is applied first.

• Unary operators (for example, prefix ++, unary +/-, logical not, and address-of &): right-to-left associativity. When multiple unary operators appear, they are grouped from right to left.

Summary: Choose array element access as the operator whose associativity is left-to-right; the other listed operators are unary and use right-to-left associativity.
