When programming in languages like C++, Java, or Python, leveraging the concept of function overloading can enhance code readability and maintainability. Function overloading allows developers to define multiple functions with the same name but different parameter lists within a class or namespace. However, there are instances when invoking an overloaded function becomes ambiguous, leading to compilation errors or unexpected behavior. Understanding the reasons behind such ambiguity and how to resolve it is crucial for writing robust and error-free code.<\/p>\n
Overloaded functions or methods in object-oriented programming are a part of polymorphism where there can be more than one function with the same name but different working. The function name can be the same but the number of parameters or the data type of the parameter can be different in the function. Thus, we get to know from this reason as well how can a call to an overloaded function be ambiguous.<\/p>\n
Function overloading is done in compile time and it is faster in execution and less flexible as compared to runtime execution which has slower execution but offers more flexibility.<\/p>\n

In the above example, it can be obvious for us to see how can a call to an overloaded function be ambiguous. As the first function has three parameters namely, score, total and grade, having three data types orderly as, integer, integer and float. The second function has two parameters, average with integer data type and grade with the character data type. <\/p>\n
Let’s look at a code to understand this concept of how can a call to an overloaded function be ambiguous.<\/strong><\/p>\n\t\t\t\t\t\t
