# How to compare equality of struct, slice and map?

DeepEqual function from reflect package used to check x and y are “deeply equal”. This applies for : Array values are deeply equal when their corresponding elements are deeply equal. Struct values are deeply equal if their corresponding fields, both exported and unexported, are deeply equal. Below is a short program to compare struct, slice or map are equal or not.
```package main

import (
"fmt"
"reflect"
)

type testStruct struct {
A int
B string
C []int
}

func main() {
st1 := testStruct{A:100,B:"Australia",C:[]int{1,2,3}}
st2 := testStruct{A:100,B:"Australia",C:[]int{1,2,3}}
fmt.Println("Struct equal: ", reflect.DeepEqual(st1, st2))

slice1 := []int{1,2,3,4}
slice2 := []int{1,2,3,4}
fmt.Println("Slice equal: ", reflect.DeepEqual(slice1, slice2))

map1 := map[string]int{
"x":1,
"y":2,
}
map2 := map[string]int{
"x":1,
"y":2,
"z":3,
}
fmt.Println("Map equal: ",reflect.DeepEqual(map1, map2))
}
```
