Program For Decimal To Binary Conversion

Code for Decimal To Binary Conversion
Code: C

`#include<stdio.h>void main(){    int i,n1,t,w,a[100],i1=0;    float n,f2;        clrscr();    printf("[B]PROGRAM FOR DECIMAL TO BINARY CONVERSION[/B]\n");    printf("******************************************\n");    printf("\n\nENTER A NUMBER:");    scanf("%f",&n);    w=n;    f2=w;        if(f2==n)    {        printf("");f2=0;    }    else    {        f2=n-f2;    }    n1=n;        for(i=0;n1>=1;i++)    {        t=n1%2;        n1=n1/2;        i1++;        a[i]=t;    }        printf("\n\nBINARY EQVALENT=>");        for(i=(i1-1);i>=0;i--)    {        printf("%d",a[i]);    }    printf(".");        for(i=1;i<=6;i++)    {        f2=f2*2;        if(f2>=1)        {            printf("1");            f2=f2-1;        }        else        {     printf("0");        }    }    getch();}`

Re: Program For Decimal To Binary Conversion

We already have a similar program in the following article Decimal, Hex, octal and binary number inter conversion. The program is Decimal to binary.

hex to octal conversion

Hi,
I am new member of this site. I am not getting how to convert Hexadecimal number into octal no. AND vice-versa.

Thanks.

Re: hex to octal conversion

Supriya,
Shabbir already provide a good article for number conversion.Go thru it for all type of number conversions.
For your reference i make a slight touch to existing (Shabbir) program.
To convert Hexadecimal no to octal no......(I just combined two functions into a single one)

Coding listed below:
//first convert Hex to Dec number
//Next convert Dec to Oct number

Code: CPP

`#include<stdio.h>#include<string.h>#include<math.h>void main(){    char hex[100];    double dec=0.0;    int oct[100],temp[100];    int len,i,j,num=0;        printf("Enter a hexadecimal number");    scanf("%s",hex);    len=strlen(hex);        for(i=0;i<len;i++)    {        switch(hex[i])        {        case '0':            temp[i]=hex[i]-48;     //Ascii code of 0 is 48  48-48=0//            break;        case '1':            temp[i]=hex[i]-48;    //Ascii code of 1 is 49  49-48=1//            break;        case '2':            temp[i]=hex[i]-48;    //Ascii code of 2 is 50  50-48=2//            break;        case '3':            temp[i]=hex[i]-48;    //Ascii code of 3 is 51  51-48=3//            break;        case '4':            temp[i]=hex[i]-48;    //Ascii code of 4 is 52  52-48=4//            break;        case '5':            temp[i]=hex[i]-48;    //Ascii code of 5 is 53  53-48=5//            break;        case '6':            temp[i]=hex[i]-48;    //Ascii code of 6 is 54  54-48=6//            break;        case '7':            temp[i]=hex[i]-48;    //Ascii code of 7 is 55  55-48=7//            break;        case '8':            temp[i]=hex[i]-48;    //Ascii code of 8 is 56  56-48=8//            break;        case '9':            temp[i]=hex[i]-48;    //Ascii code of 9 is 57  57-48=9//            break;        case 'A':            temp[i]=hex[i]-55;     //Ascii code of A is 65 65-55=10//            break;        case 'B':            temp[i]=hex[i]-55;    //Ascii code of B is 65 66-55=11//            break;        case 'C':            temp[i]=hex[i]-55;    //Ascii code of C is 65 67-55=12//            break;        case 'D':            temp[i]=hex[i]-55;    //Ascii code of D is 65 68-55=13//            break;        case 'E':            temp[i]=hex[i]-55;    //Ascii code of E is 65 68-55=14//            break;        case 'F':            temp[i]=hex[i]-55;    //Ascii code of F is 65 69-55=15//            break;        }    }    for(i=0,j=len;i<len;i++,j--)        dec=dec+(temp[j-1]*pow(16,i));    printf("The decimal equivalent is %lg \n",dec);    num=(int)dec;    //OCTAL CONVERSION    for(i=0;num!=0;i++)    {        oct[i]=num%8;        num=num/8;    }    i--;    printf("\n Octal equivalent number:");    for(;i>=0;i--)        printf("%d",oct[i]);    printf("\n");}`

Re: Program For Decimal To Binary Conversion

do you know how to convert general tree to binary tree and vice versa?
