Repetition Notes

Hi, My name is alfred and i'm going to show u my notes about repetition using c language

1. There are 3 types of looping :For, While, Do-While
2. Syntax for repetition : FOR
    ex: for(con1;con2;con3) statement;
        - con1 = initialisation
        - con2 = condition for stopping
        - con3 = increment(+1) or decrement (-1)

 *single statement looping*
        or

  ex: for(con1;con2;con3) {
        statement1;
        statement2;
        }

*the example above is how to use for to repeat 2 or more statements*

3. In for there are 2 types of loop, which is :
        - Infinite loop : Loop with no condition, it will loop forever and will stop by using "break;".
        - Nested loop : Loop in Loop, the repetition will begin from the loop inside first.

4. While vs Do-While : The difference between while and do-while is that while will check the condition first, if it fits then it'll start to loop, meanwhile do-while will start the loop first and check the statement at the end.

5. Syntax in While : while(con1) statement;
        -con1 is usually the counter for the loop
        -statement is the thing that gets repeated

*single statement looping*

    or

  ex: while(con1) {
        statement1;
        statement2;
        }

*the example above is how to use for to repeat 2 or more statements*

 6. Syntax in Do-While : do{
                                        statement;
                                        }while(con1);

*"do" will keep looping until con1 is wrong*
*works for multi statements as well*

7. If the statement is wrong, "while" will not repeat it at all, but "do-while" will repeat it at least once

8. Break vs Continue
- Break will stop the loop or case in "switch-case"
- Continue will skip the statements inside a loop or skip to the next loop
