This is the program....I don't know how to start it....any help would be helpful.!!!!
Write a short code that promts the user to enter any 3 by 3 matrix, and then calculates its inverse.!!

Heh, perhaps you should reread your sig. Anyway, what have you got so far?
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Here's a good place to start:
Code:#include <iostream> using namespace std; int main() { // code here // also here }

well heres an example of taking in three values, might help.
Code:#include <iostream.h> int main() { int value1, value2, value3; cout<<"Enter a value: "; cin>>value1; cout<<"Enter a value: "; cin>>value2; cout<<"Enter a value: "; cin>>value3; cout<<"The values u enterd were "<<value1 <<" "<<value2<<" "<<value3<<"."<<endl; return 0; }
use a multi- dimensional array...
so instead of having all those values, you could pass them through a function as well.
so something like this to start you off.
int matrix ( int [] , int[], int[]);
int main ()
{
cout<<" Enter three values for horizontal array.";
for ( int i = 0; i < 3 ; i ++ )
cin>>value [ i ] ;
then for the second dimension , you copy and paste the above code. im not writing this for you, so figure out the the function to pass the int[ ] through
HET TETRA REMEMBER THIS.....
"i am supposed to write a program that will assign seats on a ten seat plane. dont worry, im not asking you to write code for me im getting a little better at this but my teacher still sucks... so here is what i have.
btw. the program asks the person to pick a number , ( 1 for first class and 2 for seoncd.) im supposed to use arrays.... so..this is what i have but it doesnt work well... any help would be appreciated emensly." -TETRA
I posted the code for the program...........did you ever look at IT???!!!!? Here it is again....
did this program a few days ago....here it is...the complete program......check if it works.....
Code://air #include <iostream.h> int main() { int plane[11]={0}; int choice; int seatFound =1; int Firstclass =1; int Economy =6; int people =1; cout<< "Please type 1 for \"First Class\"" << endl; cout<< "Please type 2 for \"Economy\"" << endl; cin>> choice; while (choice != -1) { if(choice==1) { seatFound= 0; choice=1; while (choice<6) { if(plane[choice]<1 && Firstclass <=5) { seatFound=choice; plane[choice] =1;//put person in seat choice=33;//exit loop } else choice ++; people++; } if(seatFound>0)//test if seat is found { cout<<"Boarding Pass"<<endl; cout<<"-First Class-"<<endl; cout<<"Seat#" << seatFound<<endl; } else { cout << "Do you want a seat in economy? " << endl; cout << "\n1 = yes , 2 = no : "; cin >> choice; if ( choice == 2 ) { seatFound=0; choice=2; while(plane[choice]<11) { if(plane[choice] > 0 && Economy <= 10 ) { plane[choice]=2; // put someone in the seat seatFound=choice; choice=33; } else choice++; people++; } if(seatFound>0) //test if seat is found { cout<<"Boarding Pass"<<endl; cout<<"Economy Class"<<endl; cout<<"Seat#" << seatFound << endl; } } else { cout << "Next flight leaves in three hours..." << endl; } } } else //economy class { seatFound=0; choice=6; while(plane[choice]<11) { if(plane[choice] < 1) { plane[choice]=1; // put someone in the seat seatFound=choice; choice =2; } else choice++; people++; } if(seatFound>0) //test if seat is found { cout<<"Boarding Pass"<<endl; cout<<"Economy Class"<<endl; cout<<"Seat#" << seatFound << endl; } else { cout << "Next flight leaves in three hours..." << endl; } } cout<< "Please type 1 for \"First Class\" " << endl; cout<< "Please type 2 for \"Economy\" " << endl; cin>> choice; } return 0; }

No, you're right, I was too lazy to look at it before. I love your subject line!
I think You must use Code Tags.. for posting codes...Originally posted by Little Tito
