Any base to any base conversion
Do you like this story?
The Program for any base to any base conversion:
This program converts a given number in any base(2,8,10,16) to any base that user wants.here we use two functions one is "other_to_decimal" which is for converting a number from any base to decimal,; and other is "decimal_to_other" which is for converting a number from decimal to any base..
//Any Base to Any Base...
#include<stdio.h>
#include<conio.h>
long signed int other_to_decimal(long signed int,long signed int);
long signed int decimal_to_other(long signed int,long signed int);
void main()
{
long signed int inputbase,outputbase,inputnumber,outputnumber,s;
clrscr();
printf("Enter the number and its base:");
scanf("%ld%ld",&inputnumber,&inputbase);
printf("Enter the base you want to convert the number to:");
scanf("%ld",&outputbase);
if(outputbase==10)
{
outputnumber=other_to_decimal(inputnumber,inputbase);
}
else
{
if(inputbase==10)
{
outputnumber=decimal_to_other(inputnumber,outputbase);
}
else
{
s=other_to_decimal(inputnumber,inputbase);
outputnumber=decimal_to_other(s,outputbase);
}
}
printf("The converted number is %ld",outputnumber);
getch();
}
long signed int other_to_decimal(long signed int inputnumber,long signed int inputbase)
{
long signed int k,op,s,p;
op=0;
k=inputnumber;
p=1;
while(k!=0)
{
s=k%10;
k=k/10;
op=op+s*p;
p=p*inputbase;
}
return op;
}
long signed int decimal_to_other(long signed int outputnumber,long signed int outputbase)
{
long signed int op=0,p,k,s;
k=outputnumber;
p=1;
while(k!=0)
{
s=k%outputbase;
k=k/outputbase;
op=op+s*p;
p=p*10;
}
return op;
}
and the output is like:
