这段代码有一些语法错误，我帮你修正一下：

#include<iostream> 
using namespace std; 

class complex { 
private: 
    double real; 
    double imag; 
public: 
    complex (double r, double i) : real(r), imag(i) {} 
    friend complex operator* (complex &a, complex &b); 
    friend complex operator/ (complex &a, complex &b); 
    void print() { 
        cout<<"("<<real<<" + "<<imag<<"i)"<<endl; 
    } 
}; 

complex operator* (complex &a, complex &b) { 
    complex temp; 
    temp.real = a.real * b.real - a.imag * b.imag; 
    temp.imag = a.real * b.imag + a.imag * b.real; 
    return temp; 
} 

complex operator/ (complex &a, complex &b) { 
    double t = 1 / (b.real * b.real + b.imag * b.imag); 
    complex temp; 
    temp.real = (a.real * b.real + a.imag * b.imag) * t; 
    temp.imag = (a.imag * b.real - a.real * b.imag) * t; 
    return temp; 
} 

int main() { 
    complex c1(2.5, 3.7); 
    c1.print(); 
    complex c2(4.2, 6.5); 
    c2.print(); 
    complex c3 = c1 * c2; 
    c3.print(); 
    complex c4 = c1 / c2; 
    c4.print(); 
    return 0; 
}

这个程序实现了复数类 `complex` 的乘法和除法运算符重载。在 `main` 函数中，我们创建了两个复数对象 `c1` 和 `c2`，并分别调用了它们的 `print` 方法打印出实部和虚部。然后，我们使用 `*` 运算符计算了它们的乘积，并使用 `/` 运算符计算了它们的商，最后打印出结果。
