What does this code do in C and what prints in console: printf (#variable##”hello”) ?
I have a question about some C code. Can you help me understand what printf(#variable##”hello”) does and what prints in the console?
Sure, I can help with that. The printf function in C is used to print formatted text to the console. #variable# is a preprocessor directive that substitutes the variable name in place of #variable#. So, if the variable name is "world", printf(#variable##“hello”) will print "worldhello" to the console.
