operator precedence
State True/False: "If two operators in an expression have equal precedence but different associativity then order of their evaluation is compiler dependent." Considering my adaptation to this question: if * and ^(exponentiation) has same precedence if * associate from right to left and ^ associates from left to right, then what will be the result of 2*2^3*4 ?
