How to Convert an Array of Strings to an Array of Integers in Go ?

Answer

To convert an array of strings to an array of integers in Go, you can use a loop to parse each string element into an integer.

✐ Examples

1 Convert Strings to Integers

In this example,

We have an array of strings named strArray containing string representations of integers.
We initialize an integer array intArray with the same length as strArray.
We use a loop to parse each element of strArray into an integer and store it in intArray.
We print the contents of intArray to demonstrate the conversion.

Go Program

package main
import (
    "fmt"
    "strconv"
)
func main() {
    strArray := []string{"10", "20", "30"}
    intArray := make([]int, len(strArray))
    for i, str := range strArray {
        intVal, err := strconv.Atoi(str)
        if err == nil {
            intArray[i] = intVal
        }
    }
    fmt.Println("Converted array of integers:", intArray)
}

Output

Converted array of integers: [10 20 30]
