Question

An if statement uses these keywords:

then

if

end

else

Answer 1

The keywords you've listed are commonly associated with control flow statements in programming, particularly in languages like Pascal or certain scripting languages. However, in programming languages such as Python, Java, and C, the structure of an `if` statement slightly differs. Here’s how the `if` statement typically works in some popular programming languages:

### Pascal Example
In Pascal, you would structure an `if` statement like this:

```pascal
if condition then
begin
// code to execute if condition is true
end
else
begin
// code to execute if condition is false
end;
```

### Python Example
In Python, the syntax is more streamlined:

```python
if condition:
# code to execute if condition is true
else:
# code to execute if condition is false
```

### Java Example
In Java, the structure is as follows:

```java
if (condition) {
// code to execute if condition is true
} else {
// code to execute if condition is false
}
```

### C Example
Similarly, in C, the syntax looks like this:

```c
if (condition) {
// code to execute if condition is true
} else {
// code to execute if condition is false
}
```

### Summary
The keywords you mentioned (`if`, `then`, `end`, and `else`) may not apply directly to all programming languages, but they illustrate conditional logic. The exact syntax will depend on the programming language you are using.
