Bit Position is set in c

Check if nth Bit in a 32 bit Integer is Set or not

#include

#include

int result,position;

           int n_bit_position(int x,int position);

void main()

{

    unsigned int number;

    clrscr();

    printf("Enter the unsigned integer:\n");

    scanf("%d", &number);

    printf("enter position\n");

    scanf("%d", &position);

    n_bit_position(i, position);

    if (result & 1)

        printf("YES\n");

    else

        printf("NO\n");

}

 int n_bit_position(int number,int position)

{

    result = (number>>(position));

    getch();

}

Output

Enter the unsigned integer:

101

enter position

4

NO

Enter the unsigned integer:

113

enter position

4

YES

Check if a given Bit Position is set to One or not

#include 

#include 

void main()

{

    unsigned int number;

    int result, position;

    clrscr();

    printf("Enter the unsigned integer:\n");

    scanf("%d", &number);

    printf("enter position to be searched\n");

    scanf("%d", &position);

    result = (number >> (position));

    if (result & 1)

        printf("TRUE\n");

    else

        printf("FALSE\n");    

        getch();

}

Output

Enter the unsigned integer:

128

enter position to be searched

7

TRUE

Count the Number of Bits set to One using Bitwise Operations

#include 

#include 

int main()

{

    unsigned int number;

    int count = 0;

    clrscr();

    printf("Enter the unsigned integer:\n");

    scanf("%d", &number);

    while (number != 0)

    {

        if ((number & 1) == 1)

            count++;

        number = number >> 1;

    }

    printf("number of one's are :\n%d\n", count);

    return 0;

    getch();

}

Output

Enter the unsigned integer:

128

number of one's are :

1

Enter the unsigned integer:

-127

number of one's are :

26
