CONDITIONALS

IF

if(i == 1)
  puts("1");
    
 * the braces {} are optional when there's only one statement

IF/ELSE

if(i == 1)
  puts("1");
else if(i == 2)
  puts("2");
else if(i == 3)
  puts("3");
else
  puts("Others");
    
 * the braces {} are optional when there's only one statement

SWITCH

switch(i) {
  case 1: 
    puts("Only one?"); break;
  case 2: 
    puts("I want more."); break;
  case 3: 
    puts("Not bad."); break;
  case 4: 
    puts("Okay.");
}

 * A break statement terminates the execution of the nearest 
   enclosing switch or the nearest enclosing loop. The execution 
   resumes with the statement present next to the terminated switch 
   statement or the terminated loop
