please answer my question​

Answer 1

Explanation:

When you declare a variable, you should also initialize it. Two types of variable initialization exist: explicit and implicit. Variables are explicitly initialized if they are assigned a value in the declaration statement. ... Declare only one variable per line, even if multiple variables of the same type exist.

Answer 2

Answer:

A declaration of a variable is where a program says that it needs a variable. For our small programs, place declaration statements between the two braces of the main method. The declaration gives a name and a data type for the variable. It may also ask that a particular value be placed in the variable.

Example: int a=10; int a=b+c; a=10; a=b+c; Multiple variables can be initialized in a single statement by single value, for example, a=b=c=d=e=10; NOTE: C variables must be declared before they are used in the c program.
