For Loop

[makan007]

int a = 5;

for (int ctr = 0; ctr < 4; ctr++)
     a = a - 1;//1
     a = a + 3;//2
cout << a << endl;

I need to know whether you need to evaluate both //1 & //2 after the loop or just //1?

what you wrote could also be written like this:

int a = 5;

for (int ctr = 0; ctr < 4; ctr++){
     a = a - 1;//1
    cout << a << endl;
}
     a = a + 3;//2
cout << a << endl;

and then you could see what is happening.

if you want it to do both write it like this:

int a = 5;

for (int ctr = 0; ctr < 4; ctr++){
     a = a - 1;//1
     a = a + 3;//2
}
cout << a << endl;

I hope I did not misunderstand your question.
