Answers:

Declaring a variable means describing its type to the compiler but not allocating any space for it. Defining a variable means declaring it and also allocating space to hold the variable. You can also initialize a variable at the time it is defined.



int a;//declaration

int a=10;//intialisation

int a;
a=10;//defnition
