按字典顺序排序是一种常见的排序方法，可以使用多种编程语言来实现。以下是几种常见的编程语言的代码示例：

1. Python:

words = ["apple", "banana", "orange", "grape"]
words.sort()
print(words)  # 输出：['apple', 'banana', 'grape', 'orange']

2. Java:

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        String[] words = {"apple", "banana", "orange", "grape"};
        Arrays.sort(words);
        System.out.println(Arrays.toString(words));  // 输出：[apple, banana, grape, orange]
    }
}

3. C++:

#include 
#include 
#include 
using namespace std;

int main() {
    vector words = {"apple", "banana", "orange", "grape"};
    sort(words.begin(), words.end());
    for (string word : words) {
        cout << word << " ";  // 输出：apple banana grape orange
    }
    return 0;
}

4. JavaScript:

let words = ["apple", "banana", "orange", "grape"];
words.sort();
console.log(words);  // 输出：["apple", "banana", "grape", "orange"]

这些代码示例使用不同的编程语言实现了按字典顺序排序。你可以根据你使用的编程语言选择适合你的代码示例。
