Can you declare two variables with the same name?

It’s not possible, an if statement has no special scope, so you can’t have two variables with the same name within the same scope and access both, the latter will overwrite the former, so they should have different names.

Why is it not possible to declare more than one variable of a structure?

Do not declare more than one variable per declaration. Declaring multiple variables in a single declaration can cause confusion regarding the types of the variables and their initial values.

What happens if you give two variables the same name?

You’ll have the same result as though you didn’t have it, meaning foo will be overwritten with the new value.

Can two variables have the same name in C++?

Do not use the same variable name in two scopes where one scope is contained in another. A block should not declare a variable with the same name as a variable declared in any block that contains it.

When two variables have the same name but one is global and one is local the JavaScript program will not run?

When a global and local variable share the same name, a JavaScript program will not compile. Functions are made up of two parts, the name and the parameters. How do you get an answer from a function? You return it.

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

You can declare local variables with the same name as a global variable, but the local variable will shadow the global. As long as your local a is in scope, the symbol a refers to your local variable.

Can you declare more than one variable with the same name in Python?

Given above is the mechanism for assigning just variables in Python but it is possible to assign multiple variables at the same time. Python assigns values from right to left.

How can you declare multiple types of variables in one in Java?

You can also assign multiple variables to one value: a = b = c = 5; This code will set c to 5 and then set b to the value of c and finally a to the value of b . One of the most common operations in Java is to assign a new value to a variable based on its current value.

What happens if you declare a global and local variable with the same name?

It is usually not a good programming practice to give different variables the same names. If a global and a local variable with the same name are in scope, which means accessible, at the same time, your code can access only the local variable.

Can you declare multiple variables inside a program with the same identifier names?

Said in simple terms, if multiple variables in a program have the same name, then there are fixed guidelines that the compiler follows as to which variable to pick for the execution.

Can you declare the same instance variable name more than once in a class?

It is illegal to declare the same variable name more than once within a block. If you give the same name to a class’s instance field and to a local method variable, the instance variable overrides the method’s local variable.

What happens when both local and global variables have the same name in JavaScript?

If local variable and global variable have same name then changing value of one variable does not affect on the value of another variable. For example, variables defined in if block can be accessed outside if block, inside a function.

It’s not possible for two variables to share the same name within the same scope: one of them always wins. Since that’s true, there’s no reason for the compiler to allow you to create two variables with the same name within the same scope.

How to declare multiple variables and assign one value?

Declare multiple variables and assign one value. There’s one more way of declaring multiple variables in Python and assign values. This way is when you have one and the same value for the variables: x = y = z x = y = z = 1 x = y = z = [‘x’] x, y, z = True.

Is it possible to declare two variables of the same type?

@Walfrat Yes the variable is always declared of the same type. If two variables of the same name but with different type are declared globally the the gcc outputs error “conflicting types for a (variable)” – yoyo_fun Oct 4 ’17 at 14:48 You cannot declare a local variable even once.

How many times can you declare a global variable in C?

In C, a definition of a global variable can be used for a declaration multiple times. But if the program only has extern int x;, which is a declaration, the compile will abort since there is no place where memory is allocated to the variable.
