c++ - Conditioning for the four cases of the signs of two numbers -


i have 2 numbers , b. condition 4 cases of signs of these 2 numbers. do

if ((a >= 0) && (b >= 0)){   // }; if ((a >= 0) && (b < 0)){   // }; if ((a < 0) && (b >= 0)){   // }; if ((a < 0) && (b < 0)){   // };

one produce function outputs different values in each case , use switch{ case:} statement. functions have thought doesn't improve number of comparisons, there no gain.

which way recommended doing conditioning?

well, guess of if-s put inside else-s of others not conditions have evaluated always.

if (a >= 0) {     if (b >= 0)     {     }     else // b < 0     {     } } else // < 0 {     if (b >= 0)     {     }     else // b < 0     {     } }
