Sometimes, it makes sense to perform a sequence of expressions as though they were a single statement. This would rarely be used or make sense in a normal statement.
We can string multiple expressions together in sequence using the , operator. Each expression is evaluated from left to right in the order they appear. The value of the entire expression is the resultant value of the rightmost expression.
For instance, consider the following:
int x = 0, y = 0, z = 0; // declare and initialize.
...
...
x = 3 , y = 4 , z = 5;
...
...
x = 4; y = 3; z = 5;
...
...
x = 5;
y = 12;
z = 13;
The single line assigning all three variables is perfectly valid. However, in this case, there is little value in doing it. The three variables are either loosely related or not related at all from what we can tell in this snippet.
The next line makes each assignment its own expression and condenses the code from three lines to one. While it is also...
