What is the logic behind this code to find this output?

Question

int a=14;
for( int i = 0; i<=7; i ++)
{
a++;
}
cout<<a;

Answer 1

When loop runs first time "a" becomes 15 and "i" becomes 1 so when "a" becomes 21 ,"i" becomes 7 ,since "i" is still less than equal to 7 so loops runs one last time and a final value comes out as 22

Answer 2

8 times incrementing 'a' value.

Just a quiz question..?
