2 programs of FON.

1)Write a program to convert character to binary with ASCII.

#include
#include
void main()
{
int n1,c,i,rev[10],j=0;
char ch;
clrscr();

printf("Enter a Character:");
scanf("%c",&ch);
n1=(int)ch;
printf("The ASCII of %c is %d ",ch,n1);
c=n1;
while(c!=0)
{
i=c%2;
c/=2;
rev[j++]=i;
}
printf("Binary of %c is \n",ch);
for(i=j-1;i>=0;i--)
{
printf("%d",rev[i]);
}
getch();
}



2)Write a program to covert a decimal number into a binary number.

#include
#include
void main()
