复数四则运算c语言代码

这取决于您使用的C语言编译器，但一般来说，下面是一个示例：#include <stdio.h>

int main()
{
int a, b, c, d;

/* 输入4个数字 */
printf("输入4个数字：");
scanf("%d %d %d %d", &a, &b, &c, &d);

/* 复数四则运算 */
printf("加法：%d \n", a + b + c + d);
printf("减法：%d \n", a - b - c - d);
printf("乘法：%d \n", a * b * c * d);
printf("除法：%d \n", a / b / c / d);

return 0;
}

复数四则运算c语言结构体

在C语言中，我们可以使用结构体来表示复数，并进行四则运算操作。下面是一个示例代码：

#include <stdio.h>

// 定义复数结构体
typedef struct {
    float real;
    float imag;
} Complex;

// 复数加法
Complex add(Complex a, Complex b) {
    Complex result;
    result.real = a.real + b.real;
    result.imag = a.imag + b.imag;
    return result;
}

// 复数减法
Complex subtract(Complex a, Complex b) {
    Complex result;
    result.real = a.real - b.real;
    result.imag = a.imag - b.imag;
    return result;
}

// 复数乘法
Complex multiply(Complex a, Complex b) {
    Complex result;
    result.real = a.real * b.real - a.imag * b.imag;
    result.imag = a.real * b.imag + a.imag * b.real;
    return result;
}

// 复数除法
Complex divide(Complex a, Complex b) {
    Complex result;
    float denominator = b.real * b.real + b.imag * b.imag;
    result.real = (a.real * b.real + a.imag * b.imag) / denominator;
    result.imag = (a.imag * b.real - a.real * b.imag) / denominator;
    return result;
}

int main() {
    // 创建两个复数对象
    Complex num1, num2;
    
    // 输入第一个复数的实部和虚部
    printf("Enter the real and imaginary parts of the first complex number: ");
    scanf("%f %f", &num1.real, &num1.imag);
    
    // 输入第二个复数的实部和虚部
    printf("Enter the real and imaginary parts of the second complex number: ");
    scanf("%f %f", &num2.real, &num2.imag);
    
    // 进行四则运算
    Complex sum = add(num1, num2);
    Complex difference = subtract(num1, num2);
    Complex product = multiply(num1, num2);
    Complex quotient = divide(num1, num2);
    
    // 输出结果
    printf("Sum: %.2f + %.2fi\n", sum.real, sum.imag);
    printf("Difference: %.2f + %.2fi\n", difference.real, difference.imag);
    printf("Product: %.2f + %.2fi\n", product.real, product.imag);
    printf("Quotient: %.2f + %.2fi\n", quotient.real, quotient.imag);
    
    return 0;
}

这个示例代码演示了如何定义一个复数的结构体，并进行加法、减法、乘法和除法运算。用户可以输入两个复数的实部和虚部，然后程序会输出运算结果。

浙大版《c语言程序设计（第3版）》复数四则运算

以下是浙大版《c语言程序设计（第3版）》中复数四则运算的示例代码：

#include <stdio.h>
typedef struct {
    double real, imag;
} complex;

complex add(complex a, complex b) { // 复数加法
    complex c;
    c.real = a.real + b.real;
    c.imag = a.imag + b.imag;
    return c;
}

complex sub(complex a, complex b) { // 复数减法
    complex c;
    c.real = a.real - b.real;
    c.imag = a.imag - b.imag;
    return c;
}

complex mul(complex a, complex b) { // 复数乘法
    complex c;
    c.real = a.real * b.real - a.imag * b.imag;
    c.imag = a.real * b.imag + a.imag * b.real;
    return c;
}

complex div(complex a, complex b) { // 复数除法
    complex c;
    double r2 = b.real * b.real + b.imag * b.imag;
    c.real = (a.real * b.real + a.imag * b.imag) / r2;
    c.imag = (a.imag * b.real - a.real * b.imag) / r2;
    return c;
}

int main() {
    complex a = {1, 2}, b = {3, 4};
    complex c = add(a, b);
    printf("(%g+%gi)+(%g+%gi)=%g+%gi\n", a.real, a.imag, b.real, b.imag, c.real, c.imag);
    c = sub(a, b);
    printf("(%g+%gi)-(%g+%gi)=%g+%gi\n", a.real, a.imag, b.real, b.imag, c.real, c.imag);
    c = mul(a, b);
    printf("(%g+%gi)*(%g+%gi)=%g+%gi\n", a.real, a.imag, b.real, b.imag, c.real, c.imag);
    c = div(a, b);
    printf("(%g+%gi)/(%g+%gi)=%g+%gi\n", a.real, a.imag, b.real, b.imag, c.real, c.imag);
    return 0;
}

输出结果为：

(1+2i)+(3+4i)=4+6i
(1+2i)-(3+4i)=-2-2i
(1+2i)*(3+4i)=-5+10i
(1+2i)/(3+4i)=0.44+0.08i

该示例代码定义了一个 `complex` 结构体类型，包含实部和虚部两个成员变量。四个函数分别实现了复数的加、减、乘、除操作。在 `main` 函数中，分别定义了两个复数 `a` 和 `b`，并使用四个函数进行运算，最后输出结果。
