### FY_BCA_C_SLIP 30_2

Slip no : 30_2 Write a C prog to convert decimal no into binary,octal, hexadecimal write seperate user defined function for each option

#include<stdio.h>
#include<conio.h>

void binary(int no)
{
int a[20],i; i=0; while(no>0)

{
a[i]=no%2;
no=no/2;
i++;
}
printf("\n Binary no is : "); for(i=i-1;i>=0;i--)
{
printf("%d",a[i]);
}
}

void octal(int no)
{
int a[20],i; i=0; while(no>0)

{
a[i]=no%8;
no=no/8;
i++;
}
printf("\n Octal no is : "); for(i=i-1;i>=0;i--)
{
printf("%d",a[i]);
}
}

void hexa(int no)
{
int a[20],i; i=0; while(no>0)

{
a[i]=no%16;
no=no/16;
i++;
}
printf("\n Hexadecimal no is : "); for(i=i-1;i>=0;i--)
{ if(a[i]<10) printf("%d",a[i]); else

{
switch(a[i])
{
case 10: printf("A"); break;

case 11: printf("B"); break;

case 12:printf("C"); break;
case 13:printf("D"); break;
case 14:printf("E");
break;
case 15:printf("F"); break;
}
}
}//end of for
}

main()
