int a; for (a=1; a<6;++a); //or int a; for (a=1; a<6;++a){} /*final value of a will be 6 , bcz after a=6 ... condition'll become false& so loop stops*/

a doesn't exist as it's scope is limited to the loop.

As John said, it a doesn't exist in the outside scope. However, you can do something like this: int a; for (a=1; a<6;++a) ; a will be 6 after the loop.

for loop will first check the condition i.e., a<6 and after that it will increment the value of a
