B.1.9 Assignment

We can assign the value of an expression to a variable using the assignment operator =. For example,

lhs = rhs;

assigns the expression rhs to lhs. The object on the right-hand side of the = sign (i.e., rhs) can 
be any expression. The object on the left-hand side (i.e., lhs) must be a variable name, with one 
exception. For example, the statement

s = 3 + 5;

sets the value of variable s to 8.

The left-hand side of an assignment can also indicate that a certain element of a list is to receive 
the value on the right-hand side. For example,
*****************************************************************************/

IntegerList iL(0, 1, 2, 3);

iL[2] = 10;

/*****************************************************************************
replaces the third element with 10, causing the list to become

{0, 1, 10, 3}

Note that lists are indexed starting at 0. So writing
*****************************************************************************/

iL[0] = 55;

/*****************************************************************************
causes the list to be {55, 1, 10, 3} which we can see by printing it:
*****************************************************************************/

Print( iL );

}}
