1. The for Loop Syntax: Same as: for (expression1;condition; expression2)
statement; { }
Same as:
expression1;
while (condition)
expression2;

2. Example for Loop int numEmployees,curNum;
cout << “Enter Number of Employees: “;
cin >> numEmployees;
if (numEmployees > 0) {
for (curNum = 0; curNum < numEmployees;curNum++)
cout << “Welcome to CorpLand!” << endl; }

3. Looping for Input char letterEntered = ‘A’;
while (letterEntered != ‘Z’) {
cout << “Enter a letter: “;
cin >> letterEntered; }

4. Looping until Flag bool noMoreData(); bool done = false; …
while (!done) {
// do a bunch of stuff
if (noMoreData() == true)
done = true; }
cout << “We’re all through – thank you!”;

5. Nested Loops int i , j ; for (i=0; i < 10; i++) {
for (j=0; j < 10; j++)
cout << i << j << “ “; }
cout << endl;

6. The do-while Loop
Syntax do
statement;
while (condition); { }

7. do-while Example char letterEntered; do {
cout << “Enter a letter: “;
cin >> letterEntered; }
while (letterEntered != ‘Z’);

8. What Is This? while (stringEntered != “apple”) {
cout << “Enter a red fruit: “;
cin >> stringEntered; }
while (stringEntered != “banana”)
cout << “Enter a yellow fruit: “;
while (stringEntered != “pomegranate”)
cout << “Enter a random fruit: “;

9. What Is This? for (i = 0; i < 10 ; i++)
cout << “Interesting, isn’t it?” << endl;
while (answer != ‘D’) {
cout << “Enter an answer: “;
cin >> answer; }

10. What Is This? void kingsChair(int loopCounter) { int num;
for(num = 0; num < loopCounter; num++)
cout << “AAAAAAAAAAAAAAAAAAAAAAAAAA” << endl; }
