How to use printf() without using a semicolon

This question in particular has no importance with respect to programming but can be seen as C puzzle question.

To use printf without using we use the return type of the printf function. The printf function returns the number of characters printed as a scalar integer type. This can be used in conjunction with IF, WHILE and SWITCH statement as these statements take a integer value (scalar value) as expression. The implementation can be as follows :

if(printf ( ” Hello, World!\n ” ) ) {  }

while (! printf( “ Hello , World!\n “)) {   }

switch( printf( “ Hello, World! \n ”) ) {   }
