Which statement is a real life example of an if statement?
Real-life example Suppose we want to go out for a movie the first thing we will check before moving out is if it is raining or not(if condition) if it is raining we will not go to watch the movie(blocks inside if condition didn’t run because it is raining outside and the condition is not met).
What is the statement of if else statement?
The if/else statement executes a block of code if a specified condition is true. If the condition is false, another block of code can be executed. The if/else statement is a part of JavaScript’s “Conditional” Statements, which are used to perform different actions based on different conditions.
How can you relate conditional statements in real life?
Conditional Statement Examples
- If my cat is hungry, then she will rub my leg.
- If a polygon has exactly four sides, then it is a quadrilateral.
- If triangles are congruent, then they have equal corresponding angles.
Can you have multiple else if statements?
You can have as many else if statements as necessary. In the case of many else if statements, the switch statement might be preferred for readability. As an example of multiple else if statements, we can create a grading app that will output a letter grade based on a score out of 100.
Why the order of the if-else else if statements matter?
Yes, the order of the conditions matters. In your code, you test if(a==b) first. If all 3 integers are the same, then this will be true and only return c; will execute. It won’t even bother with the rest of the conditions.
When should an if-else statement be used?
Use an if/else statement if the two conditions are mutually exclusive meaning if one condition is true the other condition must be false.
What is difference between if and if else statement?
The if statement is a decision-making structure that consists of an expression followed by one or more statements. The if else is a decision-making structure in which the if statement can be followed by an optional else statement that executes when the expression is false.
What’s the difference between ELSE and ELSE IF?
The difference between else and else if is that else doesn’t need a condition as it is the default for everything where as else if is still an if so it needs a condition.
Can the converse of a statement be true?
If the statement is true, then the contrapositive is also logically true. If the converse is true, then the inverse is also logically true….Example 1:
| Statement | If two angles are congruent, then they have the same measure. |
|---|---|
| Converse | If two angles have the same measure, then they are congruent. |
Is converse always true?
The converse of a statement is formed by switching the hypothesis and the conclusion. The converse of a definition, however, must always be true. If this is not the case, then the definition is not valid.
Can a if else statement work without else block?
Answer 526897a4abf821c5f4002967. An if statement looks at any and every thing in the parentheses and if true, executes block of code that follows. If you require code to run only when the statement returns true (and do nothing else if false) then an else statement is not needed.
