C Exercises: Print the roots of Bhaskara’s formula from the given three floating numbers

C Basic Declarations and Expressions: Exercise-20 with Solution

Write a C program to print the roots of Bhaskara’s formula from the given three floating numbers. Display a message if it is not possible to find the roots.

Pictorial Presentation:

C Code:

#include <stdio.h>
#include <math.h>    
int main() {
	double a, b, c, pr1;  	
	printf("\nInput the first number(a): "); 
    scanf("%lf", &a);
    printf("\nInput the second number(b): "); 
    scanf("%lf", &b);
    printf("\nInput the third number(c): "); 
    scanf("%lf", &c);
    
	pr1 = (b*b) - (4*(a)*(c));
		
    if(pr1 > 0 && a != 0) {
		double x, y;
		pr1 = sqrt(pr1);
		x = (-b + pr1)/(2*a);
		y = (-b - pr1)/(2*a);
		printf("Root1 = %.5lf\n", x);
		printf("Root2 = %.5lf\n", y);
	} 
	else
	 {
		printf("\nImpossible to find the roots.\n");
	}
	
	return 0;
}

Sample Output:

Input the first number(a): 25                                          
                                                                       
Input the second number(b): 35                                         
                                                                       
Input the third number(c): 12                                          
Root1 = -0.60000                                                       
Root2 = -0.80000

Previous: Write a C program that accepts 4 integers p, q, r, s from the user where q, r and s are positive and p is even. If q is greater than r and s is greater than p and if the sum of r and s is greater than the sum of p and q print "Correct values", otherwise print "Wrong values".
Next: Write a C program that reads an integer and check the specified range where it belongs. Print an error message if the number is negative and greater than 80.
Specified Range: [0, 20], [21, 40], [41, 60], [61, 80]
