Question

How is a general if statement definition written correctly?

1) if (condition) { // code block }
2) if (condition) then { // code block }
3) if (condition) { // code block } else { // code block }
4) if (condition) then { // code block } else { // code block }

Answer 1

The correct formulations for a general if statement are 'if (condition) { // code block }' for a simple condition, and 'if (condition) { // code block } else { // code block }' for a conditional with an alternate block of code for a false condition.

Step-by-step explanation:

The correct way to write a general if statement definition in most programming languages is as follows:

1. if (condition) { // code block }
2. if (condition) { // code block } else { // code block }

The first example shows a simple if statement that will execute the code block only if the condition is true. The second example includes an else statement, which will execute a different block of code if the condition is false. It's important to note that the keyword then is not used in conjunction with if statements in many programming languages, and so the examples that include then are not generally correct.
