C++ Programming Concepts

Pass-by-reference in C++ allows functions to modify the actual argument values, as opposed to creating a copy of the argument values (pass-by-value).
Reference parameters in pass-by-reference are initialized using the 'reference' operator (&), which creates an alias for the original variable.
Pass-by-reference means that a reference to the variable's memory location is passed to the function, allowing direct modification of the variable.
It is more efficient than pass-by-value because it avoids creating a copy of large data structures, reducing memory usage and improving performance.
The key difference between pass-by-reference and pass-by-value is that pass-by-value sends a copy of the variable, whereas pass-by-reference sends a reference, allowing modifications to the original variable.
