The for Loop Syntax: Same as: for (expression1;condition; expression2) statement; { } Same as: expression1; while (condition) expression2;
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; }
Looping for Input char letterEntered = ‘A’; while (letterEntered != ‘Z’) { cout << “Enter a letter: “; cin >> letterEntered; }
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!”;
Nested Loops int i , j ; for (i=0; i < 10; i++) { for (j=0; j < 10; j++) cout << i << j << “ “; } cout << endl;
The do-while Loop Syntax do statement; while (condition); { }
do-while Example char letterEntered; do { cout << “Enter a letter: “; cin >> letterEntered; } while (letterEntered != ‘Z’);
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: “;
What Is This? for (i = 0; i < 10 ; i++) cout << “Interesting, isn’t it?” << endl; while (answer != ‘D’) { cout << “Enter an answer: “; cin >> answer; }
What Is This? void kingsChair(int loopCounter) { int num; for(num = 0; num < loopCounter; num++) cout << “AAAAAAAAAAAAAAAAAAAAAAAAAA” << endl; }
