COMPUTER CONCEPTS AND PROGRAMMING IN C

THEORY

1. Define a Digital Computer. Draw a neat block diagram for so explaining all itsfunctional units.

2. What is the difference between digital and analog computer? Explain with suitableexamples.

3. Define memory unit and its types. Differentiate between RAM & ROM.4. What is an Operating System? Give the classifications of OS.5. Explain the various data types in C giving suitable examples of each. Also give the

classification of operators in C.

6. What do you understand by the term Algorithm?7. Explain the various symbols used in a Flowchart.8. What is the difference between algorithm and flowchart?9. What is an operator? What are the various types of operators? Define with examples.10.What do you mean by programming language? What are its classifications? Explain

the Top-Down development approach.

11.Differentiate between syntax error and logical error.12.What is the use of header file? Discuss with examples.13.What is the difference between definition and declaration of a variable? Explain with

example.

14.What is the scope of variable?15.Explain the use of all conditional statements and program loops available in C.16.Why do we use do-while loop in C? How is it different from while loop?17.What is an array? What are the merits and demerits of array?18.What are pointers? Why are they required? How do you declare and initialize them?19.What is the meaning of prototype of a function? What is the difference between pass

by value and pass by reference?

20.What is the purpose of using structure in C? Explain with the help of an example.21.Discuss the different storage classes in C.22.What are the merits and demerits of static and dynamic memory allocation

techniques?

NOTE:Im not giving questions from Number System. Do practice all types of

conversions and ns & (n+1)s complement methods yourself.

i)

Whether the entered number is prime or notii) The square root of the entered numberiii) Whether the number is even or odd(Hint: Use Switch-Case for user choice of operation)

4. Write a program to calculate the sum of digits of a number.5. Write a program to find the reverse of any number and find the whether it is

palindrome or not.

6. Write a program in C to take as input a number and print whether it is Armstrong ornot.

.

Write a program in C using array to read the data and determine the following

(assume M.M. is 100 for each subject)

i) Total Marks obtained by each student.ii) The highest marks in each subject and the Roll No. of the student who secured

it.

(Hint: use structures)
