Earn while u Learn

this C code will print 1 to 100. It is a very good example of  using " while loop " in C.
Code:
__________________________________________________________
#include(stdio.h)
#include(conio.h)
main()
{
int x=1;
while(x<=10)
{
printf(\n\t"%d",x);
x++;
}
getch();
}

this program will help you to find the absolute value of a number, it will also help you to teach little kids absolute value.
Code:
__________________________________________________________
#include(stdio.h)
#include(conio.h)
main()
{
int a,abs;
printf("Enter a number");
scanf("%d",&a);
if(a>=0)
{
printf("\t\n\t%d is the absolute value of %d",a,a);
}
else
{
abs=(-1)*a;
printf("\t\n\t%d is the absolute value of %d",abs,a);
}
getch();
}

if(a>b)
{
printf("%d is greater than %d\n",a,b);
}
else if(a,b)
{
printf("%d is less than %d\n",a,b);
}
else
{
printf("%d is equal to %d\n",a,b);
}
getch();
}
