<Li> Java does not have uninitialized variables . Fields of classes and objects that do not have an explicit initializer and elements of arrays are automatically initialized with the default value for their type (false for boolean, 0 for all numerical types, null for all reference types). Local variables in Java must be definitely assigned to before they are accessed, or it is a compile error . </Li> <Li> Python initializes local variables to NULL (distinct from None) and raises an UnboundLocalError when such a variable is accessed before being (re) initialized to a valid value . </Li> <Li> D initializes all variables unless explicitly specified by the programmer not to . </Li> <P> Even in languages where uninitialized variables are allowed, many compilers will attempt to identify uninitialized variables and report them as compile - time errors . </P>

What is the value that an uninitialized variable will have in c++
