In most programming languages, such as Python, Java, C, C++, and JavaScript, an if statement does not necessarily require a specific symbol at the end of the statement. However, the syntax rules for if statements vary slightly between languages. Here are the general requirements by language:
- **Python**: No special symbol is required at the end of an if statement, but the block of code to be executed if the condition is true must be indented.
```python
if condition:
# code to execute if condition is true
```
- **Java**: An if statement must end with a curly brace (`}`) to denote the end of the block, but the actual `if` line does not have a special ending symbol. It does, however, require an opening curly brace (`{`) if multiple statements are in the block.
```java
if (condition) {
// code to execute if condition is true
}
```
- **C and C++**: Similar to Java, the if statement must have curly braces to denote the start and end of a block of code, but no special symbol is required at the end of the if line itself.
```c
if (condition) {
// code to execute if condition is true
}
```
- **JavaScript**: Also similar to Java and C/C++, an if statement in JavaScript does not require a special symbol at the end of the line. It uses curly braces to enclose a block of statements.
```javascript
if (condition) {
// code to execute if condition is true
}
```
In languages like Python, colons (`:`) are used after the condition to indicate the start of the block; however, it's not considered an ending symbol for the if statement but rather a part of its structure. None of the options provided (`:`, `.`, `#`, `“`) are universally required at the end of an if statement across different programming languages.
