寻找二次方程的根的C程序
In this tutorial, we will be discussing a program to find the roots of the Quadratic equation.
Given a quadratic equation of the form ax2 + bx + c. Our task is to find the roots x1 and x2 of the given equation.
For this, we are using the deterministic method, in this
D = √b2 - 4ac
then the roots of the equation will be
x1 = (-b + D)/2a ,and
x2 = (-b - D)/2a
Example
#include #include #include //calculating the roots of equation void calc_roots(int a, int b, int c) { if (a == 0) { printf("Invalid Equation"); return; } int d = b*b - 4*a*c; double sqrt_val = sqrt(abs(d)); if (d > 0) { printf("Roots are both real and different
