A call to an overloaded function can be ambiguous when there are multiple functions with the same name but different parameter types or number of parameters. In such cases, the compiler may not be able to determine which function to call based on the provided arguments.
For example, let’s say we have two functions named “add” in a program:
1. int add(int a, int b)
2. float add(float a, float b)
If we make a function call like “add(5, 10)”, the compiler will not be able to determine whether we want to call the first function or the second function because both can accept two integer arguments. This ambiguity can lead to a compilation error.
To resolve this ambiguity, we can explicitly specify the type of the arguments or convert them to the desired type. For example, we can call the first function by explicitly specifying the argument types like this: “add(int(5), int(10))”. Alternatively, we can convert the arguments to the desired type like this: “add(float(5), float(10))”.
By providing clear and unambiguous arguments, we can help the compiler determine which overloaded function to call.
