Eww, I've always hated switch. :yuck: You can do so much more with if statements...
But anyways, there are two routes you can go with this. You could have 4 separate Y/N questions that ask "Would you like to do an addition problem?" etc. Or you could do a strcmp and actually have the user type out what they want. That portion of the code could look something like this:
Side note: I'm weird and use printf and scanf instead of cin and cout. I would show you this with cout if I knew the syntax, but I don't. Sorry. I'm pretty sure it's similar, though.
Code:
#include string.h //obviously, put in the carrot things
int main
{
char questiontype[21]; //declare a string that takes users input
//your code
//when you get to the part where they choose:
printf("Would you like to do addition, subtraction, multiplication, or division?\n");
printf("Type in all lowercase letters, and don't misspell anything.\n");
scanf("%21[^\n]", questiontype); //user types what kind of question
flushall(); //required for scanf
if(strcmp(questiontype, "addition") == 0) //if string that took user input is identical to the phrase "addition"
{
//whatever you do to make the questions about addition
}
if(strcmp(questiontype, "subtraction") == 0) //if string that took user input is identical to the phrase "addition"
{
//whatever you do to make the questions about subtraction
}
//repeat for division and multiplication
If you really have to use switch, then you can create an int that will take the value of a strcmp and then put in something like this:
Code:
int compare;
//code
compare = strcmp(questiontype, "addition");
switch
{
case 0: //if questiontype is identical to "addition"
//do stuff
break;
default:
break;
}
//then repeat for the other operations.
If you have any more questions, feel free to PM me or something. I know C++ pretty well, and I would be happy to help
