编写减法程序的方法取决于你希望使用的编程语言。以下是几种常见编程语言的减法程序示例:

Python

```python

a = 10

b = 5

result = a - b

print("两数相减的结果为:", result)

```

Java

```java

public class Main {

public static void main(String[] args) {

int a = 10;

int b = 5;

int result = a - b;

System.out.println("两数相减的结果为: " + result);

}

}

```

C++

```cpp

include

using namespace std;

int main() {

int a = 10;

int b = 5;

int result = a - b;

cout << "两数相减的结果为: " << result << endl;

return 0;

}

```

JavaScript

```javascript

var a = 5;

var b = 3;

var result = a - b;

console.log("结果: " + result);

```

C

```csharp

using System;

class Program {

static void Main() {

int a = 5;

int b = 3;

int result = a - b;

Console.WriteLine("结果: " + result);

}

}

```

高精度减法(C语言)

```c

include

include

define N 100000

int gjd(int C[], int A[], int B[], int k1, int k2) {

int t = 0, i;

for (i = 0; i < k2; i++) {

if (i > 0 && C[i] == 0)

continue;

else

printf("%d", C[i]);

}

return t;

}

int cmp(int A[], int B[], int k1, int k2) {

if (k1 > k2)

return 1;

else if (k1 < k2)

return -1;

else

return 0;

}

void jianfa(int a[], int b[], int c[], int k1, int k2) {

memset(c, 0, 2 * k2 + 1);

for (int i = 1; i <= k2; i++) {

if (cmp(a, b, i, k2) >= 0)

c[i] = a[i] - b[i];

else {

c[i] = a[i] - b[i] + 10;

a[i + 1]--;

}

}

}

void shuchu(int c[], int k1) {

int i = k1;

while (i > 0 && c[i] == 0)

i--;

for (; i > 0; i--)

printf("%d", c[i]);

printf("\n");

}

int main() {

int a[N], b[N], c[2 * N + 1];

int k1, k2;

char b1[N + 1], b2[N + 1];

scanf("%s%s", b1, b2);

k1 = strlen(b1);

k2 = strlen(b2);

for (int i = 1; i <= k1; i++)

a[i] = b1[k1 - i] - '0';

for (int i = 1; i <= k2; i++)

b[i] = b2[k2 - i] - '0';

jianfa(a, b, c, k1, k2);

shuchu(c, k1);

return 0;

}

```

这些示例展示了如何在不同的编程语言中实现减法运算。你可以根据自己的需求选择合适的编程语言和实现方式。
