| 3. 4. 1. for Loops |
|
|
The for loop is a structure that loops for a preset number of times. |
The for loop is made up of two parts: condition and statement. |
The condition structure determines how many times the loop repeats. |
The statement is what is executed every time the loop occurs. |
The condition structure is contained within parentheses and is made up of three parts. |
Each part is separated by a semicolon (;). |
The first part of the condition structure initializes a variable to a starting value. |
In most cases, the variable is declared within this section as well as initialized. |
The second part is the conditional statement. |
The third and final part determines how the variable should be changed each time the loop is iterated. |
The format of the for loop looks like the following: |
|
for (initialize; condition; adjust) {
statement;
}
