Question
1) Where can you not declare a variable in a C++ program?
a) Within the parameter list of a function definition
b) Within the block of a void function.
c) Within the argument list of a function call
d) Within a block nested within another block
e) Within the block of a value returning function.
2) The call-by-reference mechanism is specified in the function declaration and definition, using a $ between the type and the parameter.
3) Define function signature:
4) A C++ structure, or struct, like the C++ array, is a homogeneous data structure. (i.e., all data is of the same type)
Explanation / Answer
1)I think we cannot declare a variable in c++ program within a block nested within another block.
2)The call-by-reference mechanism is specified in th function declaation and defination, using a "&" between the type and the parameter in c++.
3) A function signature defines the function input and output of functions.A signature can include parameter and their types.
4)Structure is a collection of variables of different data types under a single name.So, a c++ structure is not a homogeneous data structure.Hence it is a heterogeneous data structure(non homogeneous).
