6. Variables can be declared inside a for loop declaration

C++ allows you to declare a variable to be local to a loop:

using namespace std;
#include 

int main ()
{ 
 int i;                       // Simple declaration of i
 i = 487;

 for (int i = 0; i <>

Output

0 1 2 3 487

In case the variable is not declared somewhere above the loop, you may be tempted to use it below the loop. Some early C++ compilers accept this. Then the variable has the value it had when the loop ended. You shouldn't do this. It's considered bad practice:

using namespace std;
#include 

int main ()
{

 for (int i = 0; i <>

Gnu C++ compiler complain

t.cpp: In function ‘int main()’: t.cpp:12: error: name lookup of ‘i’ changed for new ISO ‘for’ scoping t.cpp:7: error: using obsolete binding at ‘i’
