The for Statement
ForStatement
For (InitStatement Expression1; Expression2)
     Statement
Example
for (lastNum = 1; lastNum <= 7; lastNum++)
{
   for (numtoPrint = 1; numtoPrint <= lastNum; numToPrint++)
      cout << numToPrint;
   cout << endl;
}
Note: The InitStatement can be the null statement and the two Expressions are optional.
Loop Example
#include <iostream>
using namespace std;
int main()
{
   int sum;
   int count;
   sum = 0;
   count = 1;
   while (count <= 1000)
   {
      sum = sum + count;
      count++;
   }
   cout << " The final sum is " << sum << endl;
}
Equivalent for Statement
#include <iostream>
using namespace std;
int main()
{
   int sum;
   int count;
   sum = 0;
   for (count = 1; count <= 1000; count++)
      sum = sum + count;
   cout << " The final sum is " << sum << endl;
}
