my today's paper

1. Write a declaration statement for an array of 10 elements of type float. Also initialize first four elements of array to 1.0, 2.0, 3.0 and 4.0.(2)
2. Which bitwise operator returns true if both bits are different and returns false if both bits are same?(2)
3. Suppose if we want to store values like 10, 45.3, 4, A, D, 6.4, and 50 by using array. Can we store all these elements by declaring a single array? Yes or no ? Give reason to support your answer(3)
4. Write the code for a structure called Inventory having the following elements:

A character array named partName

An integer named partNumber

An integer named stock. (3)

     5.Write a program which opens a file named "this.txt" and then using write() function, writes the string "Introduction to Programming" at the end of the file.(5)

      6.Write a program which declares and initializes an integer array of 10 elements and then using a pointer, displays the array elements in reverse order.

Mostly mcqs old papers men say thay

5 marks ka ik question tha jis main code likha hua tha aur us code ka logic byan krna tha .

Write the code for a structure called Inventory having the following elements:

• A character array named partName
• An integer named partNumber

An integer named stock.

Declare a 2D array of integers having two rows and three columns.

We know that random method for accessing the files increases the performance but there are certain constrainsts on it. Mention those constraints

Write the code to access the element at third row and second column of a 2D array uses pointer named arrayptr .

C++ views each file as a sequential stream of _______________.

► Bytes

► Bits

► 0’s or 1’s

► Words

If it is required to copy an array to another array then,

► Both arrays must be of the same size and data type

► Both arrays may be of different size

► Both arrays may be of different data type

► Both arrays may be of different size and type

 

What will be the output of following code?

int x = 10 ;

cout “x =” x ;

► 10

► “x=10”

► x=10

► 10=x

C++ views each file as a sequential stream of________________ .

►Bytes

►Bits

►0’s or 1’s

►Words

 

1 mcqs tha agr semicolon mising ho to kon sa error hoga. Logical,syntc,runtime or compile time

Relational operaters diay huay thay aur pucha gia tha kon say operator hen.

10+6*2/6 ko solve krna tha

if some one want to get good marks in cs 201 

you prepare from LEC no 15 say 22 

and mcsq mostly prom past papers 

[Muhammad Amin]

very easy paper tha:

• string conversion k ley kon se header file use hoti hai
• if two programs want to open a file at same time can they open or not?
• TWAIN stands for :    
• pointer are used for   ------ store memory address 

1. out put btani the 2 questions ke   4 maks
2. two programs of 10 marks

 CS201 Paper 11-May-2012 Spring

Don’t remember the exact questions but giving the main theme.
There are 
20 MCQ
2x2 Q
3x3 Q
5x5 Q

MCQ most programming base, like what is the syntax or output etc.

Q: tell the sizeof() value of a structure variable.
Q: use of the keyword “const”
Q: which of these functions are string manipulation and conversion function?
Q: a program which input a telephone number with city code and recognize if it is from lhr or not.
Q: an program is given and we have to tell the output. Program consists array and loop.
Q: how many memory locations will a pointer will jump if it is incremented.
