Can We Use Function on Left Side of an Expression in C and C++?
In C, it is not possible to have function names on the left side of an expression, but it’s possible in C++.
How can we use the function on the left side of an expression in C++?
In C++, only the functions which return some reference variables can be used on the left side of an expression. The reference works in a similar way to pointers, so whenever a function returns a reference, an implicit pointer is being returned to its return value. Therefore, through this, we can use a function on the left side of an assignment statement. The above has been demonstrated using the example given below,
Time Complexity : O(1)
Auxiliary Space: O(1)
