# Conditional Statements in Go

Conditional Statements are part of every programming language. They help us to decide which instruction is supposed to run when a certain condition is met. *e.g. If I’m hungry then I’ll eat else I’ll wait.* *e.g. If the score is greater than 35%, you passed, else you failed.*

### If `statement` in Go

```go
if condition/expression {
    //instruction to be performed
}
```

The condition needs to be true to perform the given set of instructions.

```go
package main

import "fmt"

func main(){
    i := 10
    if i % 2 == 0 {
        fmt.Printf("%d is a even number", i)
    }
}
```

### If-Else statement in Go

```go
if condition/expression {
    //instruction to be performed
} else {
    //instruction to be performed
}
```

If the condition needs to be false perform instruction from the else block.

```go
package main

import "fmt"

func main(){
    i := 11
    if i % 2 == 0 {
        fmt.Printf("%d is a even number", i)
    } else {
        fmt.Printf("%d is a odd number", i)
    }
}
```

### if-else-if ladder

We can use multiple conditional statements at once.

```go
package main

import "fmt"

func main(){
    i := -11
    if i == 0 {
        fmt.Println("It's zero")
    } else if i < 0 {
        fmt.Println("Negative number")
    } else {
        fmt.Println("Positive number")
    }
}
```

### Short statement

```go
package main

import "fmt"

func main() {
    if j := 10; j%2 == 0 {
        fmt.Println("Even number")
    }
}
```
