Grouping datas together..

[Sidro]

Hi,
Im new to C++ and have so many questions..
Lets say I wanted to do a comparison of a group of datas. What are the best ways to do them in C++? For example...
I have a bunch of if statements.

if variableA is Monday,Tuesday,Wednesday cout<<&quot;Chicken&quot;;
if variableB is Thursday,Friday,Saturday cout<<&quot;Beef&quot;;

Is there a way to group Monday,Tuesday,Wednesday into
one variable? Thursday,Friday,Saturday into one variable and compare the two variables.Example, heres what Im thinking...

Variable1=Monday,Tuesday,Wednesday;
Variable2=Thursday,Friday,Saturday;
UserInputVariable=Tuesday;

if(UseInputVariable==variable1)
{
cout<<&quot;Chicken&quot;;
}
if(UserInputVariable==Variable2)
{
cout<<&quot;Beef&quot;;
}

Can we do something like what I've presented?Or are there better ways?

Something like this (tell me if there are errors).

const int days = 3;

char *variables1[days] = {{&quot;Monday&quot;},
{&quot;Tuesday&quot;},
{&quot;Wednesday&quot;}};

char *variables2[days] = {{&quot;Thursday&quot;},
{&quot;Friday&quot;},
{&quot;Saturday&quot;}};

char *currentDay = &quot;Tuesday&quot;;

for( int i = 0; i < days; i++ )
//checks to see if values are equal
if ( strcmp( currentDay, variables ) == 0 )
cout << &quot;Chicken&quot; << endl;
else if ( strcmp( currentDat, variables ) == 0 )
cout << &quot;Beef&quot; << endl;

Something similar to this will do. (strcmp is in string.h)

Another way ...

enum day {Sunday=0,Monday=1,Tuesday=1,Wednesday=1,
Thursday=2,Friday=2,Saturday=2};

day UserDay; // declared enum day.
//...

UserDay=Tuesday;

switch(UserDay)
{
case Sunday:
cout << &quot;A day to fast.&quot; << endl;
case Monday:
case Tuesday:
case Wednesday:
cout << &quot;Eat Chicken&quot; << endl;
break;
case Thursday:
case Friday:
case Saturday:
cout << &quot;Eat Beef&quot; << endl;
break;
default:
cout << &quot;Bad Day&quot; << endl;
}

//** CAUTION:
day today = 2; //** ERR can't assign int ot enum
int bigday = today //** O.K.

goto google.com and search on: C++ enum for more stuff.
Good Luck,
