i am beginner to programming and want help,
i was making the program to find the roots of quadratic equation AX2+BX+C using functions
help me out please.
roots of the quadratic equation can be calculated using the formula
x=(-b+sqrt(bb-4ac))/2a and x=(-b-sqrt(bb-4aC))/2a
the formula to find roots of quadratic equation is
x=(-B+(B^2-4AC)^1/2)/2*A or x=(-B-(B^2-4AC)^1/2)/2*A
and a C program to get roots of quadratic equation where inputs are A,B,C respectively is given below
#include<stdio.h>
#include<math.h>
int main(){
float a,b,c;
float d,root1,root2;
printf("Enter a, b and c of quadratic equation: ");
scanf("%f%f%f", &a, &b, &c);
d = b * b - 4 * a * c;
if(d < 0){
printf("Roots are complex number.\n");
return 0;
}
else if(d==0){
printf("Both roots are equal.\n");
root1 = -b /(2* a);
printf("Root of quadratic equation is: %.3f ",root1);
return 0;
}
else{
printf("Roots are real numbers.\n");
root1 = ( -b + sqrt(d)) / (2* a);
root2 = ( -b - sqrt(d)) / (2* a);
printf("Roots of quadratic equation are: %.3f , %.3f",root1,root2);
}
return 0;
}
