Answer / arnab maji

Hey Susie,

The ## is a concatenation operator,
When you pass the two arguments they get concatenated as

i/p --> f(g,g2) g##g2
o/p --> gg2

hence
f(var,12) will give us var12

effectively the printf statement gets modified as

printf("%d",f(var,12)); --> printf("%d",var12);

hence the output is 100 ie the value of var12.
