The normal exit of program is represented by zero return value. If the code has errors, fault etc., it will be terminated by non-zero value. In C++ language, the main() function can be left without return value. By default, it will return zero.

What is the default return type in C and C plus plus?
No. There is no default return type for functions, it must be explicitly specified in both the function declaration and in the definition. To specify no return value, return void. To return a variant type, return void* (pointer to void). Otherwise return the exact type.
Why the return type of all the function by default is int in c?
Because int is the most common data-type in C. Don't rely on this though, always specify the return type explicitly.
If function does not return value by default it returns python?
If a function in Python does not explicitly return a value using the return statement, it implicitly returns None by default. This means that when you call such a function, the result will be None, indicating that no value was returned. You can check this by assigning the function call to a variable and printing it, which will show None as the output.
CAN Overloaded functions can return default values?
I'm not sure I understand you as it wouldn't make sense for a function to return a default value. Do you actually mean can a function return an argument that has a default value? If so, then yes. Any argument passed to a function, whether defaulted or not, can be returned by the same function. If the argument is passed by value then you must return it by value. If passed by reference (which cannot be defaulted) then you can either return by reference or by value. However, if you pass by non-constant reference then you can just use the reference as an output argument, and use the actual return value for some other purpose, such as reporting any error condition(s) created by the function. Overloaded functions are no different to ordinary functions, the only criteria is that each overload has an unique signature. The return value does not form any part of the signature, thus signatures cannot differ by return type alone.
Is return type can also be used in a function with return type void?
no

What part of a function definition specifies the data type of the value that the function returns?
The function header. The return value is written before the name of the function. This return type must match the type of the value returned in a return statement.
How do I use void in Python?
In Python, void is not a specific keyword or type like in some other programming languages. Instead, when you want to define a function that does not return a value, you simply define it without a return statement or use return without a value. Such a function is often referred to as returning None by default. For example: def my_function(): print("This function does not return anything.") Here, my_function() executes its code but does not return a value.
How many types of function in C?
Well, it depends on what you mean by the type of a function. There are user defined functions and library functions.
Where do you use no argument no return in c function?
Where there is no need to return any type of value from a function
