How to convert a string to an integer using strconv.Atoi() in Golang?

To convert a string to an integer using strconv.Atoi() in Golang, follow these steps:

Import the strconv package:

import "strconv"

Call the Atoi() function from the strconv package, passing the string as a parameter. This function returns an integer and an error:

number, err := strconv.Atoi("1234")

Check if the conversion was successful by checking the error. If the conversion fails, an error will be returned. Handle the error appropriately:

if err != nil {
    fmt.Println("Conversion error:", err)
    return
}

Use the converted integer number in your code:

fmt.Println("Converted number:", number)

Here's the complete example:

package main

import (
    "fmt"
    "strconv"
)

func main() {
    // Convert a string to an integer
    number, err := strconv.Atoi("1234")

    if err != nil {
        fmt.Println("Conversion error:", err)
        return
    }

    fmt.Println("Converted number:", number)
}

Output:

Converted number: 1234

Note: If the string cannot be converted to an integer, the Atoi() function will return an error. Make sure to handle the error appropriately to avoid unexpected behavior in your code.
