The illustration shows a code segment with "for" loop. The lines numbered 1 through 15 are as follows:

 //Illustrates a for loop.
 #include <iostream>
 using namespace std;

int main( )
 {
 int sum = 0;

 for (int n = 1; n <= 10; n++) //Note that the variable n is a local 
 sum = sum + n; //variable of the body of the for loop!

 cout << "The sum of the numbers 1 to 10 is "
 << sum << endl;
 return 0;
 } with "n=1" annotated as "Initializing action," "n<= 10" annotated as "Repeat the loop as
long as this is true," and "n++" annotated as "Done after each loop body iteration." 
The lines within the "for" loop are highlighted.
