Example :

with body :
#include<stdio.h>
#include<conio.h>
main ( )
{
 int i=1;
while(i<=10)
{
printf("%d",i);
i++;
}
getch( );
}
output : 12345678910

with out body:
#include<stdio.h>
main()
{
int i=0;
while(i++<10)
printf("%d",i);
getch();
}
OUTPUT :
12345678910

with semi column :
 #include<stdio.h>
main()
{
int i=0;
while(i<10);
printf("%d",i);
i++;
getch();
}
OUTPUT:
nothing will be display
