What is namespace

Posted by Deepak . 3 years, 6 months ago

CBSE > Class 12 > Computer Science

1 answers

Yogita Ingle 3 years, 6 months ago

A namespace is a way of grouping identifiers so that they don’t clash. Using a class implies that you can create an instance of that class, not true with namespaces.

A namespace cannot be created as an object; think of it more as a naming convention. It is used as additional information to differentiate similar functions, classes, variables etc. with the same name available in different libraries.

To find a program of quadratic equation ? Pls help me?

Posted by Haneen Mohammed 3 years, 6 months ago

CBSE > Class 12 > Computer Science

1 answers

Gaurav Seth 3 years, 6 months ago

C program to find roots of a quadratic equation: Coefficients are assumed to be integers, but roots may or may not be real.

For a quadratic equation ax²+ bx + c = 0 (a≠0), discriminant (b²-4ac) decides the nature of roots. If it's less than zero, the roots are imaginary, or if it's greater than zero, roots are real. If it's zero, the roots are equal.

For a quadratic equation sum of its roots = -b/a and product of its roots = c/a. Let's write the program now.

Roots of a Quadratic equation in C

#include <stdio.h>
#include <math.h>

int main()
{
int a, b, c, d;
double root1, root2;

printf("Enter a, b and c where a*x*x + b*x + c = 0\n");
scanf("%d%d%d", &a, &b, &c);

d = b*b - 4*a*c;

  if (d < 0) { // complex roots, i is for iota (√-1, square root of -1)
  printf("First root = %.2lf + i%.2lf\n", -b/(double)(2*a), sqrt(-d)/(2*a));
  printf("Second root = %.2lf - i%.2lf\n", -b/(double)(2*a), sqrt(-d)/(2*a));
  }
  else { // real roots
root1 = (-b + sqrt(d))/(2*a);
root2 = (-b - sqrt(d))/(2*a);

  printf("First root = %.2lf\n", root1);
  printf("Second root = %.2lf\n", root2);
  }

return 0;
}

Output of program:
