CS201 Final Term Paper

Suppose there is class A having data member 'x', 'y' and an object of class B. The class B has data members 'z'. Write the constructor of a class A that initializes the data members of class A and class B (using member initializing list). [2]

Find the error in the given code [3]

Code:

for (int i=0; i<numRows; i++)

{
for (int j=0; j<numCols; j++)

}
elements[i,j] =m.elements [i][j];

}
}


Determine the output of following code segment. [3]

Code:

x=5;
Switch (x)
{
case 5;
cout<<Value is 5;
case 4;
cout<<Value is 4;
break;
}
