Which of the following statements about function overloading in C++ is...
Function overloading in C++ allows the creation of multiple functions with the same name but different parameter types or a different number of parameters. The compiler determines which function to call based on the number and types of arguments.

Which of the following statements about function overloading in C++ is...
Function Overloading in C
Function overloading is a feature in C that allows multiple functions with the same name but different parameter lists to be defined. It provides a way to create functions that perform similar operations but with different inputs.
Statement Analysis
Let's analyze each statement and determine if it is true or false:
a) Function overloading allows the creation of multiple functions with different return types.
This statement is false. Function overloading does not consider the return type when determining which function to call. The return type alone cannot differentiate between overloaded functions. The compiler uses the number and types of function arguments to resolve the function call.
b) Function overloading can only be achieved by changing the function name.
This statement is false. Function overloading is achieved by using the same function name but with different parameter lists. The function name remains the same, but the number and types of parameters are different.
c) Function overloading is determined by the number and types of function arguments.
This statement is true. Function overloading is determined solely by the number and types of function arguments. When a function call is made, the compiler matches the function call with the correct overloaded function based on the number and types of arguments. If an exact match is not found, the compiler looks for the best match by considering implicit conversions.
d) Function overloading is not supported in C.
This statement is false. Function overloading is supported in C++. However, in the C programming language, function overloading is not directly supported. C requires each function to have a unique name, and the programmer must define different functions with different names to achieve similar behavior as function overloading in C++.
Conclusion
The correct statement about function overloading in C is option 'c'. Function overloading in C is determined by the number and types of function arguments. The return type alone does not differentiate between overloaded functions, and function overloading is achieved by using the same function name but different parameter lists.
