The FOR statement:

for ( Entry Expression ; 
      Boolean Expression ;
      Continuation Expression )
    Embedded Statement

Below is a flowchart of the For loop.

Example of for loop:

sum = 0;

for (count = 1; count < numofnumbers; ++count) {
   cout << "Enter next number " ;
   cin >> number ;
   sum = sum + number ;
}

cout << "Sum is " << sum << endl;
