这段代码首先提示用户输入两个整数(integers),然后分别接收这两个输入并转换为整型存储在 `int1` 和 `int2` 中。接下来,通过整除运算符 `//` 计算 `int1` 除以 `int2` 的商,结果保存在 `int3` 中;使用取模运算符 `%` 计算余数,结果存入 `int4`。
然后,代码尝试将一个新的表达式赋值给 `int1`:`int2 * int3 + int4`。这个表达式表示 `int2` 乘以 `int3` 的结果再加上 `int4` 的值。然而,需要注意的是,在Python中,直接用 `$` 符号来改变变量的值是错误的语法,应该使用等号 `=` 进行赋值操作。正确的做法应该是:
```python
int1 = int2 * int3 + int4
```
完整的代码示例:
```python
print('Please type in two integers?')
int1 = int(input())
int2 = int(input())
int3 = int1 // int2
int4 = int1 % int2
int1 = int2 * int3 + int4
print(f"The result of the calculation is: {int1}")
```

这个程序使用了递归的方式来计算斐波那契数列的每一项,并将它们打印出来。在每一次递归调用中,程序使用栈来保存f0和f1两个变量的地址,并将n的值减1传递给递归函数。在递归函数返回时,程序恢复f0和f1的地址,并将它们的值更新为下一个斐波那契数。最后,程序打印出计算出的斐波那契数列的每一项。
2.Reliability and Maintainability Simulation involves a large number of random variables. The use of dynamic arrays will greatly improve the efficiency of simulation and the scale of problem solving. Please design Vector. This problem requires the implementation of a vector class template, which can realize the storage and access of data. (1) [] operator can only access the existing elements. (2) The add method can automatically expand the internal storage space when accessing. Note that the behavior of this vector is different from that of std:: vector. Function interface definition: template <class T> class Vector { ... } Example of referee test procedure: #include <iostream> using namespace std; /* Todo: write down your code here! */ int main() { Vector<int> vint; int n,m; cin >> n >> m; for ( int i=0; i<n; i++ ) { // add() can inflate the vector automatically vint.add(i); } // get_size() returns the number of elements stored in the vector cout << vint.get_size() << endl; cout << vint[m] << endl; // remove() removes the element at the index which begins from zero vint.remove(m); cout << vint.add(-1) << endl; cout << vint[m] << endl; Vector<int> vv = vint; cout << vv[vv.get_size()-1] << endl; vv.add(m); cout << vint.get_size() << endl; } Input example: 100 50 Output example: 100 50 99 51 -1 100
Here is the implementation of the Vector class template:
```
template<class T>
class Vector {
private:
T* data; // pointer to the actual data
int capacity; // current capacity of the vector
int size; // current size of the vector
public:
// constructor
Vector() {
data = nullptr;
capacity = 0;
size = 0;
}
// copy constructor
Vector(const Vector& other) {
capacity = other.capacity;
size = other.size;
data = new T[capacity];
for (int i = 0; i < size; i++) {
data[i] = other.data[i];
}
}
// destructor
~Vector() {
if (data != nullptr) {
delete[] data;
}
}
// [] operator for accessing elements
T& operator[](int index) {
if (index >= size) {
throw std::out_of_range("Index out of range");
}
return data[index];
}
// add method for adding elements
void add(const T& value) {
if (size == capacity) {
int newCapacity = capacity == 0 ? 1 : capacity * 2;
T* newData = new T[newCapacity];
for (int i = 0; i < size; i++) {
newData[i] = data[i];
}
if (data != nullptr) {
delete[] data;
}
data = newData;
capacity = newCapacity;
}
data[size++] = value;
}
// remove method for removing elements
void remove(int index) {
if (index < 0 || index >= size) {
throw std::out_of_range("Index out of range");
}
for (int i = index; i < size - 1; i++) {
data[i] = data[i + 1];
}
size--;
}
// get_size method for getting the current size of the vector
int get_size() const {
return size;
}
};
```
In the main function, we first create a Vector object `vint` of type `int`. We read in two integers `n` and `m` from the input, and then use a for loop to add `n` elements to the vector using the `add` method. We then print the size of the vector using the `get_size` method, and print the element at index `m` using the `[]` operator. We then remove the element at index `m` using the `remove` method, and add a new element with value `-1` using the `add` method. We print the new element at index `m` using the `[]` operator. We create a new Vector object `vv` by copying `vint`, and print the last element of `vv` using the `[]` operator. Finally, we add an element with value `m` to `vv`, and print the size of `vint` using the `get_size` method.
I hope this helps!
