if (some boolean expression) { .. }
-
else { ... } // optional else

Nested: if (some boolean expression) { .. }
-
else if(another boolean) { .. }
-
else { ... }
|
|
while (any boolean) { /* Do Stuff */ }
|
|
do { /* What to do */ } while (another boolean);
|
for (expression1; booleanexpression ; expression2) { ...}
-
naturally starts with expression1, applies expression2 at end of each loop, and continues as long as booleanexpression true
-
for ( int i=0; i<length(a); i++)
-
a[i] = i * i;
-
/* loop variable i is optionally declared to be local to loop as shown here. */
