These are five papers which can be downloaded in also PDF format of cs201.mileys50:
Question 1:
Identify each of the following as system software and application
software.
LINUX, DISK CLEANUP, WORD PROCESSOR, WINDOWS, STUDENT
INFORMATION (mark 5)
Q2:
Write the explanation of this program. See program from book pg no534.
(mark5)
Q3: Write a program which defines three variables of type double which
store three different values including decimal points, using set precision
manipulators to print all these values with different numbers of digits
after the decimal number.(5)
Q4 define static variable also explain life time of static variable? (3)
Q5 what do you know about run time error? (3)
Q6 what are limitation of the friendship between classes? (3)
Q7: read the code and explain the functionality of this program? See
page 535 for cod (3)
Q8: write down the meanings of given below line of code, where m is an
object of the class matrix. If (& m = this) (2)
Q9: write the general syntax for the definition of the user defined
function? (2)
Q10: what is the source and destination of cin?(2)
Q11: write the general syntax of allocation memory dynamically to an
array using new operator? (2)
1.what is diffrent between pointer and variable?
2.What is difference between Unary and binary operators and how they
can be overloaded?
3.how many types of templates?
4.What will be the output of following function if we call this function by
passing int 5?

Code:

template T reciprocal(T x) {return (1/x); } 5. Identify the errors in the following member operator function and also correct them. math * operator(math m); math * operator (math m) { math temp; temp.number= number * number; return number; Answer: The errors are in the arguments of the member operation function and also in the body of operator member function. Correct function should be math *operator(math *m); math *operator (math *m) { math temp; temp = m; temp.number= number * number; return temp.number;

Code:

Matrix :: Matrix ( int row , int col ) { numRows = row ; numCols = col ; elements = new ( double * ) [ numRows ] ; for ( int i = 0 ; i < numRows ; i ++ ) { elements [ i ] = new double [ numCols ] ; for ( int j = 0 ; j < numCols ; j ++ ) elements [ i ] [ j ] = 0.0 ; } } Hint : This function belong to a matrix class, having Number of Rows = numRows Number of Columns = numCols Which one (copy constructor or assignment operator) will be called in each of the following code segment? 1) Matrix m1 (m2); 2) Matrix m1, m2; m1 = m2; 3) Matrix m1 = m2;
