# 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>
// Include math.h header file for mathematical functions
int main() {
double a, b, c, pr1; // Declare variables for coefficients and discriminant
// Prompt user for coefficients 'a', 'b', and 'c'
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)); // Calculate discriminant
if(pr1 > 0 && a != 0) { // Check conditions for real roots
double x, y;
pr1 = sqrt(pr1); // Calculate square root of discriminant
x = (-b + pr1)/(2*a); // Calculate first root
y = (-b - pr1)/(2*a); // Calculate second root
printf("Root1 = %.5lf\n", x); // Print first root
printf("Root2 = %.5lf\n", y); // Print second root
}
else {
printf("\nImpossible to find the roots.\n"); // Print message for no real roots
}
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

**Flowchart:**

**C Programming Code Editor:**

**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]
