This used to declare a variable constant. This means that the value of variable is unchangable. It can also be used to declare a pointer constant in that case value pointed by that pointer is unchangable. This specially desirable when we want the value passed by refrence to a function remain unchanged under all circumstances.

Code -

void function (void)
{
const int a = 10;
printf ("%d",a);
\\ a = 20;  If you remove the comments symbol this will generate an compile time error.
  
}
