BIGGEST NUMBER

#include<stdio.h>
main()
{
int x,y,big=0,sbig=0;
clrscr();
x=0;
while(x<10)
{
scanf("%d",&y);

To Find Binary Value Number Program:

main()
{
int n,i=0,j,a,g=1;
clrscr();
scanf("%d",&n);
j=n;
while(j>1)
{
a=j%2;
g=a+g*10;
j=j/2;
}
n=g;
printf("The bin value is %d\n\n",g);
while(n>0)
{
n=n/10;
i++;
}
while(i<8)
{
printf("0");
i++;
}
printf("%d",g);
}

While Loop Program:
void main()
{
int a=1;
clrscr();
while(a<=20)
{
if(a%2==0)
printf("%d is even\n",a);
else
printf("%d is odd\n",a);
a=a+1;
}
