Dear nitin,

  if ( TRUE ) Execute the next statement


if ( TRUE ) {
  // Execute these statements if TRUE
}
else {
  // Execute these statements if FALSE
}





if ( <condition> ) {
  // Execute these statements if <condition> is TRUE
}
else if ( <another condition> ) {
  // Execute these statements if <another condition> is TRUE and
  // <condition> is FALSE
}


The switch statement provides a convenient alternative to the if when dealing with a multi-way branch.  Suppose we have some integer value  called test and want to do different operations depending on whether it has  the value 1, 5 or any other value, then the  switch statement could be  employed:- 

switch ( test ) {

  case 1 : 
    // Process for test = 1
    ...
    break;

  case 5 : 
    // Process for test = 5
    ...
    break;

  default : 
    // Process for all other cases.
    ...

}
