Some Simple C Programs To Play With Bits

I like programming ie., development. Since my proffessional career started, i am working on C programming only. Thats why always i will be working on C programming. I like to work on Programming.

While working on bit related programming like setting a bit, resetting a bit in an integer, i was getting confusions. Concept and theory will be present in my mind but i will take too much time to produce on paper. Programming on the IDE or any programming tool will be easy. But to write on a paper, me like people feel little difficulty.

Hence i have written some programs and the same i am giving here. This could be helpful to many to understand bits.

1. Program to make a bit 0 if it was 1 and to make 1 if it was 0

void BitToggle()
{
    int Data, Bit;
    int t1,t2;

    printf("Enter the data \n");
    scanf("%d",&Data);

    printf("Enter the bit number to be toggled\n");
    scanf("%d",&Bit);

    if((Data >> Bit) & 0x01) //if bit is set
    {
    Data &= (~(1 << Bit));
    }
    else //if bit is not set
    {
    Data |= (1 << Bit);
    }
}

This logic is very simple and you would get a better logic than this. But this is a good program to start work wround bits. I think no explaination is required for this.


2. Program to reverse the bit order of an integer

void ReverseBitOrder()
{
    for(i=0;i<32;i++)
    {
        p = data >> i; //'data' is the value to be reversed
        t = p & 1; // 'p' and 't' are temporary variables
        result = result | (t & 1);
        result <<=1;
    }
}

This is a good program to play with bits. Also, at firt time, it has taken some more time to do this. First i have tried on a paper. But after doing program only i could able to do because of debugging.

I think these are good programs to start work around bits in C.

Goooooooooood luccccccccccccck
