Converting an Int Value to String

To convert an integer value to a string in Go, you can use the strconv package, which provides functions for handling string conversions.

Using strconv.Itoa()

The strconv.Itoa() function is specifically designed to convert an int to its string representation.

Example

package main

import (
    "fmt"
    "strconv"
)

func main() {
    num := 42
    str := strconv.Itoa(num)
    fmt.Printf("Integer: %d, String: %s\n", num, str)
}

Using fmt.Sprintf()

Another method to convert an int to a string is by using fmt.Sprintf().

Example

package main

import "fmt"

func main() {
    num := 42
    str := fmt.Sprintf("%d", num)
    fmt.Printf("Integer: %d, String: %s\n", num, str)
}

Using strconv.FormatInt()

If you need more control over the string conversion, such as specifying the base (e.g., binary, hexadecimal), you can use strconv.FormatInt().

Example

package main

import (
    "fmt"
    "strconv"
)

func main() {
    num := int64(42)
    base := 2 // Convert to binary

    str := strconv.FormatInt(num, base)
    fmt.Printf("Integer: %d, Binary String: %s\n", num, str)
}
