ifelse is a conditional statement in many programming languages, including C. It allows you to execute different sets of code based on a condition. The basic syntax of ifelse in C is:
```
if (condition) {
// code to execute if the condition is true
} else {
// code to execute if the condition is false
}
```
Here, `condition` is an expression that evaluates to either true or false. If the condition is true, the code inside the if block will be executed. Otherwise, the code inside the else block will be executed.
You can also chain multiple ifelse statements together using else if. This allows you to check for multiple conditions and execute different blocks of code accordingly. Here's an example:
```
if (condition1) {
// code to execute if condition1 is true
} else if (condition2) {
// code to execute if condition2 is true
} else {
// code to execute if all conditions are false
}
```
In this case, the conditions are evaluated from top to bottom. If any of the conditions are true, the corresponding code block will be executed. If all conditions are false, the code inside the else block will be executed.
