You can see that since in C , and therefore in C++ , you can issue an “address of”, it is not legal to have variables and functions with the same name within the same scope of resolution.

Can we define a function and a variable with same name?

Function declaration will not be executed there. Because of the same name usage the function expression overrides the function declaration. In JavaScript, function declarations are hoisted to the top of the enclosing function or global scope. Function expression of same variable name overrides the function declaration.

Can two functions have same name in C?

In C you can’t have two functions with the same name, at all. In C++, it’s entirely possible as long as the function function signature is different, ie two functions having the same name but different set of parameters.

Can you have two variables with the same name?

Can we have two variables with the same name one as an integer and the second as float in c? – Quora. Yes, if they are not in the same lexical scope. For example (we have two variables named x , one is the formal int x , and another is the double x in the inside block).

Can a variable with the same type and name be declared inside two different methods?

Answer: Yes — the scopes will not overlap so there will be two local variables, one per method, each with the same name.

Can a function and a variable have the same name in JavaScript?

Function expression of same variable name overrides the function declaration.,In JavaScript, function definitions are hoisted to the top of the current scope. Function declaration will not be executed there.

Can a pointer and variable have same name?

the question: can the code have a variable and a pointer with the same name? If they were each local to different functions (or different files) then they are in different ‘scopes’ then, YES then can have the same name. What you have is a variable names pointer whose type is int * , i.e. a pointer to an int .

Can 2 function have same name?

That is, you can use the same name for two or more functions in the same program. An overloaded function must have a parameter list that’s different from all other functions with the same name so the compiler has some way to tell the functions apart.

Can two functions have same name?

Function overloading is a feature of object oriented programming where two or more functions can have the same name but different parameters. When a function name is overloaded with different jobs it is called Function Overloading.

Can we declare local two variables in a function with same name but different data type co3?
