Solution
The statement that is not true is: "Struct variables can only be passed to functions via a pointer". In C and C++, struct variables can be passed to functions both by value and by reference (via a pointer). When passed by value, a copy of the struct is made within the function. When passed by reference, the function works directly on the original struct.
