THE "FOR LOOP", & CONTROL AND STRUCTURE  LEARNING OBJECTIVES: 1. DEFINE "FOR LOOP" 2. EXAMPLE OF "FOR LOOP" 3. UNDERSTAND CONTROL STRUCTURES 5. IDENTIFY TYPES OF CONTROL STRUCTURES 6. APPLY CONTROL STRUCTURES IN PROGRAMMING FOR LOOP THE FOR LOOP IN C++ IS A CONTROL FLOW STATEMENT THAT ALLOWS YOU TO REPEATEDLY EXECUTE A BLOCK OF CODE. IT'S PARTICULARLY USEFUL WHEN YOU KNOW IN ADVANCE HOW MANY TIMES YOU WANT THE LOOP TO RUN. 1. initialization : This statement is executed only once at the beginning of the loop. It's typically used to declare and initialize a counter variable. 2. condition : This is a boolean expression. The loop continues to execute as long as this condition is true. If it's false , the loop terminates. 3. increment/decrement : This statement is executed after each iteration of the loop. It's usually used to update the counter variable, moving it closer to the point where the condition becomes false.  EXAMPLE 1: PRINTING NUMBERS 1 TO 5 This code will print: 1 2 3 4 5 - int i = 1; : We create an integer variable i and set it to 1. This is our counter. - i B. K INCREASES OR DECREASES ACCORDING TO THE POSITIVE AND NEGATIVE VALUE OF I RESPECTIVELY.  REPEAT-WHILE STRUCTURE -IT ALSO USES A CONDITION TO CONTROL THE LOOP. THIS STRUCTURE HAS THE FORM:  REPEAT-WHILE STRUCTURE -IT ALSO USES A CONDITION TO CONTROL THE LOOP. THIS STRUCTURE HAS THE FORM:  IN THIS, THERE REQUIRES A STATEMENT THAT INITIALIZES THE CONDITION CONTROLLING THE LOOP, AND THERE MUST ALSO BE A STATEMENT INSIDE THE MODULE THAT WILL CHANGE THIS CONDITION LEADING TO THE END OF THE LOOP. THANK YOU!
