golang concat string and int

To concatenate a string and an int in Go (Golang), you can use the strconv package to convert the int to a string, and then use the + operator to concatenate the two strings together.

Here are the steps to concatenate a string and an int in Go:

1. Import the strconv package at the top of your Go file:

import "strconv"

1. Declare a variable of type int:

var num int = 42

1. Convert the int to a string using the strconv.Itoa() function:

strNum := strconv.Itoa(num)

1. Declare a string variable and assign it a value:

var str string = "The number is: "

1. Concatenate the string and the converted int using the + operator:

result := str + strNum

Now, the variable result will contain the concatenated string and int. In this example, it will be "The number is: 42".
