Types of For Loops in Salesforce: Traditional, List Iteration, Set Iteration, SOQL for Loops

C.

The correct answer to this question is C. Traditional for loops.

In Apex programming language, there are three types of loops that can be used to iterate over collections or execute a block of code multiple times. These loops are:

1. Traditional for loops
2. List iteration for loops
3. Set iteration for loops

Traditional for loops are defined using the syntax mentioned in the question:

scssCopy code
for(initstmt; exit_condition; increment stmt){     codeblock } 

In this syntax, initstmt is used to initialize a loop variable, exit_condition is a Boolean expression that defines the condition for exiting the loop, and increment stmt is used to increment the loop variable. The codeblock is executed for each iteration of the loop until the exit_condition is false.

Here's an example of a traditional for loop in Apex:

cssCopy code
for (Integer i = 0; i < 10; i++) {     System.debug('i = ' + i); } 

In this example, the loop variable i is initialized to 0, and the loop executes until i is less than 10. The System.debug statement is executed for each iteration of the loop, and the loop variable i is incremented by 1 at the end of each iteration.

List iteration for loops and Set iteration for loops are specialized versions of for loops that are used to iterate over collections. List iteration for loops are used to iterate over a list of objects, while Set iteration for loops are used to iterate over a set of objects. These types of loops have simpler syntax and are optimized for iterating over collections.

SOQL for loops are a specialized type of for loop that is used to iterate over a large number of records returned by a SOQL query. These loops use a chunking mechanism to retrieve the records in batches and can help avoid governor limits in Apex.

The other options in the question, A. Static and final and B. A governor limit, are not types of loops in Apex. Static and final are keywords used to define variables in Apex, while governor limits refer to the limits on resources, such as CPU time and database queries, that are enforced by the Apex runtime environment.
