Precedence and Associativity of Logical AND and OR
Consider the following Program: #include <stdio.h> int main() { short a = 1, b = 1, c = 1, d; d = ((a++  b++ && c++)  1); printf("a= %d, b = %d, c= %d, d= %d", a,b,c,d) ... 1; Even though the precedence of AND is greater than that of OR, which means && should be executed before , but it is not happening. Why??
