SLIPTEST QUESTIONS FOR CSE-B ON 20/11/2015(FRIDAY)

Slip test Questions for Cp To Cse-B on 20^th Nov 2015

1 Briefly explain the structure of c-program?

2 How to create, run and execute the c-program?

3 Explain the different types of operators?

4 program development steps?

Programs

1. Sum of given n numbers.

2. Perfect number?

3. Palindrome number?

4. Roots of quadratics equations?

#include <stdio.h>

#include <math.h> /* This is needed to use sqrt() function.*/

int main()

{

  float a, b, c, determinant, r1,r2, real, imag;

  printf("Enter coefficients a, b and c: ");

  scanf("%f%f%f",&a,&b,&c);

  determinant=b*b-4*a*c;

  if (determinant>0)

  {

      r1= (-b+sqrt(determinant))/(2*a);

      r2= (-b-sqrt(determinant))/(2*a);

      printf("Roots are: %.2f and %.2f",r1 , r2);

  }

  else if (determinant==0)

  {

    r1 = r2 = -b/(2*a);

    printf("Roots are: %.2f and %.2f", r1, r2);

  }

  else

  {

    real= -b/(2*a);

    imag = sqrt(-determinant)/(2*a);

    printf("Roots are: %.2f+%.2fi and %.2f-%.2fi", real, imag, real, imag);

  }

  return 0;

}

Output 1 :Enter coefficients a, b and c: 2.3

4

5.6

Roots are: -0.87+1.30i and -0.87-1.30i

Output 2    :Enter coefficients a, b and c: 4

1

0

Roots are: 0.00 and -0.25
