求解一元二次方程复数解的C语言代码

以下是求解一元二次方程复数解的C语言代码：

#include <stdio.h>
#include <math.h>

int main()
{
    double a, b, c, delta, x1_real, x1_imag, x2_real, x2_imag;

    printf("请输入一元二次方程的系数：\n");
    printf("a = ");
    scanf("%lf", &a);
    printf("b = ");
    scanf("%lf", &b);
    printf("c = ");
    scanf("%lf", &c);

    delta = b * b - 4 * a * c;

    if (delta >= 0)
    {
        x1_real = (-b + sqrt(delta)) / (2 * a);
        x2_real = (-b - sqrt(delta)) / (2 * a);
        printf("方程的实数解为：x1 = %lf, x2 = %lf\n", x1_real, x2_real);
    }
    else
    {
        x1_real = -b / (2 * a);        x1_imag = sqrt(-delta) / (2 * a);
        x2_real = -b / (2 * a);
        x2_imag = -sqrt(-delta) / (2 * a);
        printf("方程的复数解为：x1 = %lf + %lfi, x2 = %lf + %lfi\n", x1_real, x1_imag, x2_real, x2_imag);
    }

    return 0;
}
