+Another set of examples that does not use if-statement:
+
+--------
+class Test
+{
+ public int AbsOK (bool b, int i)
+ {
+ int x;
+ int y = true ? (x = i) : (x = i);
+ return x;
+ }
+
+ public int FooOK (bool b, int i)
+ {
+ int x;
+ int y = true ? (x = i) : 0;
+ return x;
+ }
+
+ public int BarOK (bool b, int i)
+ {
+ int x;
+ int y = false ? 0 : (x = i);
+ return x;
+ }
+
+ public int FooNG1 (bool b, int i)
+ {
+ int x;
+ int y = true ? 0 : (x = i);
+ return x;
+ }
+
+ public int BarNG1 (bool b, int i)
+ {
+ int x;
+ int y = false ? (x = i) : 0;
+ return x;
+ }
+
+ public int FooNG2 (bool b, int i)
+ {
+ int x;
+ int y = b ? (x = i) : 0;
+ return x;
