C Program to Convert Binary to Octal

#include 

#include 

int main()

{

    long int binarynum, octalnum = 0, j = 1, remainder;

    clrscr();

    printf("Enter the value for  binary number: ");

    scanf("%ld", &binarynum);

    while (binarynum != 0)

    {

        remainder = binarynum % 10;

        octalnum = octalnum + remainder * j;

        j = j * 2;

        binarynum = binarynum / 10;

    }

    printf("Equivalent octal value: %lo", octalnum);

    return 0;

}

Output

        

Enter the value for binary number: 10101

Equivalent octal value: 25

C Program to check whether a given Number is Armstrong

#include 

#include

#include 

void main()

{

    int number, sum = 0, rem = 0, cube = 0, temp;

    clrscr();

    printf ("enter a number");

    scanf("%d", &number);

    temp = number;

    while (number != 0)

    {

        rem = number % 10;

        cube = pow(rem, 3);

        sum = sum + cube;

        number = number / 10;

    }

    if (sum == temp)

        printf ("The given no is armstrong no");

    else

        printf ("The given no is not a armstrong no");

    getch();

}

Output

Enter a number370

The given no is armstrong no

C Program to check whether a given Number is Perfect Number

#include 

#include 

int main()

{

    int number, rem, sum = 0, i;

    clrscr();

    printf("Enter a Number\n");

    scanf("%d", &number);

    for (i = 1; i <= (number - 1); i++)

    {

        rem = number % i;

   if (rem == 0)

        {

            sum = sum + i;

        }

    }

    if (sum == number)

        printf("Entered Number is perfect number");

    else

        printf("Entered Number is not a perfect number");

    return 0;

}

Output

Enter a Number

6

Entered Number is perfect number

C Program to Shutdown or Turn off the Computer in Linux

#include

    system("Shutdown -P now");

    return 0;

}

Output

            Shutdown: Need to be root

C program to Increase 1 to all of the given Integer Digit

#include 

#include

int main()

{

    int number, sum = 0, remainder, count;

    clrscr();

    printf("Enter a number: ");

    scanf("%d", &number);

    while (number)

    {

        remainder = number % 10;

        sum  = sum + (remainder + 1);

        number /= 10;

    }

    printf("increasing 1 to all digits:  %d", sum);

    return 0;

}

Output

Enter a number: 3456

Increasing 1 to all digits:  22

C Program to add two Complex Numbers

#include 

#include

struct complex

{

   int realpart, imaginary;

};

main()

{

    struct complex a, b, c;

    clrscr();

    printf("Enter value of a and b complex number a + ib.\n");

    printf("Value of complex number a is = ");

    scanf("%d", &a.realpart);

    printf("Value of complex number b is = ");

    scanf("%d", &a.imaginary);

    printf("Enter value of c and d complex number c + id.\n");

    printf("Value of complex number c is = ");

    scanf("%d", &b.realpart);

    printf("Value of complex number d is = ");

    scanf("%d", &b.imaginary);

    c.realpart = a.realpart + b.realpart;

    c.imaginary = a.imaginary + b.imaginary;

    if (c.imaginary >= 0)

        printf("complex numbers sum is = %d + %di\n", c.realpart, c.imaginary);

    else

        printf("complex numbers sum = %d %di\n", c.realpart, c.imaginary);

    return 0;

}

Output

Enter value of a and b complex number a + ib.

Value of complex number a is = 10

Value of complex number b is = 12

Enter value of c and d complex number c + id.

Value of complex number c is = 15

Value of complex number d is = 22

Complex numbers sum is = 25 + 34i
