How to add elements to map in GoLang 1.20
0In this video we are going to generate source code for the GoLang Program, How to add elements to map using chatGPT.
After generating we will verify and run the generated code.
Important note on source code: only source code that are acceptable by the youtube description box will be displayed.
##############SOURCE CODE#########################
package main
import "fmt"
func main() {
// Declare a map of string keys and integer values
m := make(map[string]int)
// Add elements to the map using the index operator
m["one"] = 1
m["two"] = 2
m["three"] = 3
// Print the contents of the map
fmt.Println("Map contents:", m)
// Use the map literal syntax to create a map with initial elements
m2 := map[string]int{
"four": 4,
"five": 5,
"six": 6,
}
// Print the contents of the second map
fmt.Println("Second map contents:", m2)
// Add elements to the map using the built-in function make
m3 := make(map[string]int)
m3 = map[string]int{
"seven": 7,
"eight": 8,
}
// Print the contents of the third map
fmt.Println("Third map contents:", m3)
}
Below is the explanation for the program:
In this program, we first declare a map of string keys and integer values using the make() function and the syntax m := make(map[string]int).
We then add elements to the map using the index operator and the syntax m[key] = value.
We then use the map literal syntax to create a map with initial elements using the syntax m2 := map[string]int{key1: value1, key2: value2, ...}.
Next, we add elements to a map using the make() function and the syntax m3 := make(map[string]int); m3[key] = value.
Finally, we print the contents of each map using the fmt.Println() function to show the different ways in which we can add elements to a map.
