c代码-C语言编写一个程序,将两个字符串连接起来
:-1:2])) + f(b))
# 高斯求积公式
def gauss(f, a, b, n):
xi, wi = np.polynomial.legendre.leggauss(n)
x = (b-a) / 2 * xi + (a在大多数编程语言中,连接两个字符串可以使用字符串拼接操作符或函数。以下是几种不同语言的示例代码:
Python:
```python
str1 = "Hello"
str2 = "World"
result = str1+b) / 2
return (b-a) / 2 * np.sum(wi * f(x))
# 计算插值 + " " + str2
print(result)
# Output: "Hello World"
```
Java:
```java
String str1 = "多项式
xi = np.array([-5,-3,-1,1,3,5])
yi = f(xi)
xx = npHello";
String str2 = "World";
String result = str1 + " " + str2;
System.out.println(result);
// Output:.linspace(-5, 5, 100)
yy = L(xx, xi, yi)
# 绘制插值多项式和原 "Hello World"
```
C++:
```cpp
#include <iostream>
#include <string>
int main() {
std::string str函数
plt.plot(xx, f(xx), label='f(x)')
plt.plot(xx, yy, label='L(x)')
plt.legend()
plt1 = "Hello";
std::string str2 = "World";
std::string result = str1 + " " + str2.show()
# 计算积分(均匀节点)
I1 = trapezoidal(f, -5, 5, 10;
std::cout << result << std::endl;
// Output: "Hello World"
return 0;
}
```
JavaScript)
I2 = simpson(f, -5, 5, 10)
I3 = gauss(f, -5, 5,:
```javascript
let str1 = "Hello";
let str2 = "World";
let result = str1 + " " + str2 10)
print('积分结果(均匀节点):', I1, I2, I3)
# 计算积分;
console.log(result);
// Output: "Hello World"
```
注意,每种语言可能具有不同的字符串连接方法,但这些示例代码应该可以为你提供一个起点。
