Web3 sep. 2024 · First, a++ evaluates to 0, and increments a later. But even if it evaluated to a non-zero value, == binds more strongly than && (has higher precedence), so your expression is equivalent to 0 && ( (a++) == 0), which is false regardless of what (a++) == 0 evaluates to. The precedence of == is higher than &&. Add parentheses (0 && (a++))==0. Web13 nov. 2013 · In C++ The result of pow (0, 0) the result is basically implementation defined behavior since mathematically we have a contradictory situation where N^0 should always be 1 but 0^N should always be 0 for N > 0, so you should have no expectations mathematically as to the result of this either. smart apps pty ltd
