pls i need a c++ code to add, subtract, multiply, and find deteminant of matrix 2x2 or 3x3

must it be c++, what about other languages MATLAB could be easier u know!! its just a matter of manipulating 2-3 dimensional arrays!!!!

its some crazy assignment dats why i have no other choice

//C++ to Add, Subtract and Multiply
#include<iostream>
using namspace std;
int add(int, int); //function prototypes
int sub(int, int);
int mut(int , int);
int main()
{
int choice,c,d,total;
cout<<"1. Addition\n";
cout<<"2. Subtraction\n";
cout<<"3. Multiplication\n";
cout<<"Enter Your Choice";
cin>>choice;
switch(choice)
{
case 1: cout<<"You Selected Addition\n";
cout<<"Enter Two Numbers:";
cin>>c,d;
total=add(c,d);
cout<<"Result is "<<total;
break;
case 2: cout<<"You Selected Subtraction";
cout<<"Enter Two Numbers:";
cin>>c,d;
total=sub(c,d);
cout<<"Result is "<<total;
break;
case 3: cout<<"You Selected Multiplication";
cout<<"Enter Two Numbers:";
cin>>c,d;
total=mut(c,d);
cout<<"Result is "<<total;
break;
default: cout<<"Unknown Selection";
break;

}
return 0;
}
int add(int a, int b){
return a+b;
}
int sub(int a, int b){
return a-b;
}
int mut(int a, int b){
return a*b;
}

//C++ for 2x2 Matrices
#include<iostream>
using namespace std;

int main()
{
int a[][];
int b[][];
int c[][];
int n,i,j;
cout<<"Enter the number of elements\n";
cin>>n;
cout<<"Enter First Array Elements\n";
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
cin>>a[i][j];
}
}
cout<<"\n";
cout<<"Enter Second Array Elements\n";
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
cin>>b[i][j];
}
}
cout<<"\n";
cout<<"Result Of Matrices After Multiplication\n";
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
c[i][j]=a[i][j]*b[i][j];
cout<<c[i][j]<<"\n";
}
}

return 0;

}


I just wrote this program here didnt compile it, so try and correct minor errors you might encounter. thanks

the code is nice but 2 many errors need to debug and their are some functions you used i haven't been taught c ++ up to dat .. still a leaner tho
