编写加和的程序可以根据不同的编程语言有不同的实现方法。以下是几种常见编程语言的加和程序示例:

C语言

```c

include

int main() {

int a, b, sum;

a = 123;

b = 456;

sum = a + b;

printf("sum is %d\n", sum);

return 0;

}

```

Python

```python

num1 = int(input("请输入第一个数:"))

num2 = int(input("请输入第二个数:"))

sum = num1 + num2

print("两个数的和为:", sum)

```

Java

```java

public class SumExample {

public static void main(String[] args) {

int a = 5;

int b = 3;

int sum = a + b;

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;

}

```

JavaScript

```javascript

let a = 5;

let b = 3;

let sum = a + b;

console.log("The sum is:", sum);

```

函数式编程(Python)

```python

def add_numbers(a, b):

return a + b

result = add_numbers(3, 5)

print(result) 输出 8

```

多项式相加(C语言)

```c

include

int main() {

int num1, num2, sum;

printf("请输入两个数:\n");

scanf("%d%d", &num1, &num2);

sum = num1 + num2;

printf("sum=%d\n", sum);

return 0;

}

```

阶乘累加和(C语言)

```c

include

int fun(int n) {

if (n == 1)

return 1;

else

return n * fun(n - 1);

}

int main() {

int n, sum = 0, i;

printf("请输入一个值,求1到n的累加值:\n");

scanf("%d", &n);

for (i = 1; i <= n; i++) {

sum += fun(i);

}

printf("累加和为:%d\n", sum);

return 0;

}

```

这些示例展示了如何在不同的编程语言中实现加和的功能。你可以根据自己的需求和熟悉程度选择合适的编程语言进行编写。
