Nested If...Else Statements: Unlocking Complex Conditional Branching
Which of the following statements about nested if...else statements is true?
a) Nested if...else statements are not allowed in programming.
b) Nested if...else statements cannot contain logical conditions.
c) Nested if...else statements can be used to create complex conditional branching.
d) Nested if...else statements are always more efficient than single if statements.
Final answer:
Nested if...else statements are allowed in programming, can contain logical conditions and be used to create complex conditional branching; however, they aren't always more efficient than single if statements.
Explanation:
The correct answer to your question, 'Which of the following statements about nested if...else statements is true?' is option c) Nested if...else statements can be used to create complex conditional branching.
Nested if...else statements are indeed allowed in programming, and can contain logical conditions. This enables programmers to create complex conditional branching, where the output is dependent on multiple layers of conditions.
For example, consider the below block of code:
If (condition 1 is true) {
If (condition 2 is true) {
Execute task A
} Else {
Execute task B
}
Else {
Execute task C
}
However, nested if...else statements are not always more efficient than single if statements. The efficiency largely depends on the complexity of the program and coding practices.
