Python:
```python
输入两个数
num1 = int(input("请输入第一个数:"))
num2 = int(input("请输入第二个数:"))
计算两个数的和
sum = num1 + num2
输出结果
print("两个数的和为:", sum)
```
Java:
```java
public class AddTwoNumbers {
public static void main(String[] args) {
int num1 = 5;
int num2 = 3;
int sum = num1 + num2;
System.out.println("The sum is: " + sum);
}
}
```
C++:
```cpp
include using namespace std; int main() { int a = 5; int b = 3; int sum = a + b; cout << "The sum is: " << sum << endl; return 0; } ``` C语言: ```c include int main() { int num1 = 5, num2 = 10; int sum = num1 + num2; printf("两数之和为:%d\n", sum); return 0; } ``` JavaScript (Node.js): ```javascript const readline = require('readline'); const rl = readline.createInterface({ input: process.stdin, output: process.stdout }); rl.question('请输入第一个数: ', function(num1) { rl.question('请输入第二个数: ', function(num2) { const sum = parseInt(num1) + parseInt(num2); console.log('两个数的和为:', sum); rl.close(); }); }); ``` Dart: ```dart void main() { int num1 = 10; int num2 = 20; int sum = num1 + num2; print('The sum of $num1 and $num2 is $sum'); } ``` 这些示例展示了如何在不同的编程语言中实现两数相加的功能。你可以根据所使用的编程语言选择合适的代码片段进行尝试。
