COMPUTER SCIENCE ARRAYS

3.b) An array T[15][10] is stored in the memory with each element requiring 2 bytes of storage. If the base address of T is 2000, determine the location of T[7][8] when the array VAL is stored (i) Row major (ii) Column major.

Solution: Children, Try this as an assignment.

3.c) Write a user-defined function in C++ to find and display the sum of diagonal elements from a 2D array R[7][7] containing integers.

void displaysum( )
{ int i,j,D1=0,D2=0,R[7][7];
cout<<”\nEnter any 49 values….”;
for(i=0;i<7;i++)
for(j=0;j<7;j++)
{ cin>>R[i][j];
if(i= = j)
D1=D1+R[i][j];
else if ((i+j)= =(size-1))
D2=D2+R[i][j];
}
cout<<”\nThe sum of the elements of the Main Diagonal = “<<D1;
cout<<”\nThe sum of the elements of the Other Diagonal = “<<D2;
}
