For static and global variables it is 0; automatic variables are not initialized by default.

in the c language there is no default value for non static local variables. The variable holds whatever was in memory before it became a variable. It's best to always initialize a non static local variable before using it in the c language (or at least before comparing it to something else). Also It's best to assume that there is no default value because this varies from language to language, and hardware to hardware.

Cheers!

What is the default value of integer in java?

What is default value of integer in c plus plus?

The default value is whatever happens to be present in the memory location at the point of allocation. If allocated on the stack, it will generally be zero. On the heap it could be anything, and must be initialised before being used.


Can you use expressions in switch?

Switch Expression should be an Integer Expression.Syntax:switch(integer expression){case constant 1:do this;default:do this;}The expression following the keyword switch is any C expression that will yield an Integer value.It could be an integer constant like 1,2 or 3,or an expression that evaluates to an integer.

What does default mean in a computer language?

Default means the state or condition something will have unless you specify otherwise.In C++, you may specify the interface to a function as:int foo(int a, int b, int c=3.14)You may call the function in two ways, one specifying an explicit value for the 3rd argument 'c', and the other where you omit specifying a value for 'c' and it will use the default value of 3.14 from the interface specification for 'c'.Thus 3.14 is the default value of 'c' unless you specify otherwise.

What is the default value of int in c?

I'm not sure. I have written C programs in which the default value was what ever happened to be in the variable's memory location when the space was allocated. So it could be 0. Or it could be anything. That is why it is always important to initialize variables when using C. I don't know if this is true with modern C compilers. No default value for automatic variables, 0 for others.

The default return type for functions in c plus plus is integer?

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.


Can an float value be assigned to int variable?

In C a float value can be assigned to an integer variable but an implicit casting occurs when compiler forces a float value to be assigned as an integer. So that the digits after the decimal notation in the float value get loss after assigning a float to an integer.eg:int a=12.356;// Implicit casting occursprintf("%d",a);// when printing a it shows as 12 as an integer
