Program : To obtain solution of second order quadratic equation
#include<stdio.h> #include<conio.h> #include<math.h> void main() { float a,b,c; float desc,root1,root2; clrscr(); printf("nEnter the Values of a : "); scanf("%f",&a); printf("nEnter the Values of b : "); scanf("%f",&b); printf("nEnter the Values of c : "); scanf("%f",&c); desc = sqrt(b*b-4*a*c); root1 = (-b + desc)/(2.0*a); root2 = (-b - desc)/(2.0*a); printf("nFirst Root : %f",root1); printf("nSecond Root : %f",root2); getch(); }
Output :
Enter the Values of a : 1 Enter the Values of a : -5 Enter the Values of a : 6 First Root : 3.000000
