The for Statement

Finally let us cover the for Statement. Three separate parts control a loop:

1. an initialization,
2. a continuation condition, and
3. an update.

You'll see what I'm talking about when you see the code. The syntax for the for statement is

for (initialization; continuation condition; update) statement;

The initialization, the continuation condition, or the update may be empty. Here is an example:

#include <iostream.h> int main() { int n1, sum; cout << "Enter a number to be counted: "; cin >> n1; for(int i = 0; i < n1; i++) { sum = i+1; cout << sum << "n"; } return 0; }

This program will ask the user to enter a number, and then once it receives the number it will count up to that number and stop. Here the initialization is int i = 0, the continuation condition is i < n1, and the update is i++. In the for loop, the sum is the counter i + 1, each time it goes threw the loop it will add one to the sum. The first time around the sum is changed to 1, the 2nd time it is 2 and so on.
