When is a switch statement better than multiple if statements? Ans. A switch statement is generally best to use when you have more than two conditional expressions based on a single variable of numeric type. For instance, rather than the code if (x == 1) printf('x is equal to one.\n'); else if (x == 2) printf('x is equal to two.\n'); else if (x == 3) printf('x is equal to three.\n'); else printf('x is not equal to one, two, or three.\n'); the following code is easier to read and maintain: switch (x) { case 1: printf('x is equal to one.\n'); break; case 2: printf('x is equal to two.\n'); break; case 3: printf('x is equal to three.\n'); break; default: printf('x is not equal to one, two, or three.\n'); break; } Notice that for this method to work, the conditional expression must be based on a variable of numeric type in order to use the switch statement. Also, the conditional expression must be based on a single variable. For instance, even though the following if statement contains more than two conditions, it is not a candidate for using a switch statement because it is based on string comparisons and not numeric comparisons: char* name = 'Lupto'; if (!stricmp(name, 'Isaac')) printf('Your name means 'Laughter'.\n'); else if (!stricmp(name, 'Amy')) printf('Your name means 'Beloved'.\n '); else if (!stricmp(name, 'Lloyd')) printf('Your name means 'Mysterious'.\n '); else printf('I haven't a clue as to what your name means.\n');
