   <\description-compact>
+    <item*|assignment>An expression in which a variable is set to a value.
+    For example, in the expression <hgroup|<cpp|x = 1>>, the variable <cpp|x>
+    is set to the value <cpp|1> because <cpp|x> is to the left of the equals
+    sign \ \P<cpp|=>\Q. The value of the entire expression is equal to the
+    value of the left hand side (i.e. <cpp|x> in this example) after the
+    assignment is performed. For example, the following C code will print
+    \P<cpp|true>\Q:
+
+    <\cpp-code>
+      #include \<less\>stdio.h\<gtr\>
+
+      int main() {
+
+      \ \ int c;
+
+      \ \ if( (c = 7) == 7 )
+
+      \ \ \ \ printf("true");
+
+      \ \ else
+
+      \ \ \ \ printf("false");
+
+      };
+    </cpp-code>
+
+    As another example, the following lines are equivalent:
+
+    <\cpp-code>
+      a = b = c = 0;
+
+      a = ( b = ( c = 0 ) );
+    </cpp-code>

     <item*|declaration<label|term declaration>>A construct that establishes
