The C++ programming language is known for its strength and is extensively employed in the gaming console sector. It includes the feature of overloading, allowing functions to share the same name but differ in parameters, with the compiler effectively distinguishing between them.
In contrast, the arguments vary, while the function identifiers remain constant. In this scenario, we employ the name mangling technique to differentiate functions sharing identical names, enabling the compiler to recognize them as distinct entities. This approach introduces supplementary details to the processes, ensuring their uniqueness. Consequently, both local and online compilers can execute them seamlessly without any ambiguity.
C++ Code
Example
// here we are writing down the tiny code snippet to demonstrate the
// concept of Name Mangling and extern "C" in C++, function overloading in C++
// programming language and name mangling concept
int v(void) { return 1; }
// this is a sample integer variable declared with a return type 0.
int v(int) { return 0; }
// A simple void function holding integer variables i and j.
void hh(void) { int i = v(), j = v(0); }
// end of the Name Mangling and extern "C" in C++ concept partial
