Introduction To Programming

Differentiate between array and structure. Define an array or structure with an example.

Give function name, syntax and corresponding header file to achieve the following:- 

(c) To clear the output buffer.

What is logical error? How does logical error differ from run time error and syntax error? Support your answer with examples.

Define an algorithm and list its characteristics. Write an algorithm for measuring 4 liter of water if only 5 liter and 3 liter jugs are available.

Define associativity of operators. Write the output of the following statements. All are integer values.

Define break statement. How does continue statement differ from break statement?

Give function name, syntax and corresponding header file to achieve the following:- 

(f) To read the whole line from input.

Give function name, syntax and corresponding header file to achieve the following:- 

(e) To read the character Un-buffered.

Give function name, syntax and corresponding header file to achieve the following:- 

d) To read the buffered strings.

Describe storages classes in C with suitable examples.

Give function name, syntax and corresponding header file to achieve the following:- 

(b) to clear the input buffer.

Give function name, syntax and corresponding header file to achieve the following:- 

(a) To open a file in read mode.

(b) In C, when arrays are passed to the function, which mechanism do they follow? Is there any relation between pointers and array's name? Explain. 

Describe various operators used in C language. Which operator has the highest precedence?

Using the for loop, write a program to print the sum of first n odd numbers.

Using the do-while loop, write a program that prints the factorial of n.

Using the while statement, write a program that reverses the digits n.

Describe the methods of parameter passing with the help suitable examples.

What do you mean by recursion? Write a program using a recursive function.

What are pointers? Why are they needed? Explain with an example.

Give two matrices.Write a program to calculate product of two matrices such that:

Declare a structure for employee' record. Also determine size of this structure.

Define a random access file. What are the various operations commonly used in file handling? Discuss with examples.

Write short notes on Argument passing using pointers

Write short notes on Array of pointer.

Write short notes on Call by reference

What is meant by function? List its characteristics and name five in- built functions with their purpose.

Describe the various phases of compilations. Is there any relation between compilation and pre processor directives? Justify your answer.

Q2 (a) Differentiate between auto, static, extern local and global variable with respect to their lifetime, scope and access rights.

(b) Differentiate between do-while and while-do loop with the help of an example. 

Q3 (a) Write a program in C which reads a string and after finding its length, program print back the string in reverse order. Do not use any in built function. 

(b) What do you mean by enumerated data types? Are they different from strings? Explain their use. 

Q4 (a) Differentiate between Sequential/Random files in terms of the time taken for insertion, deletion and updation of records. 

(a) Write a program in C which reads an array of size n, find how many numbers in the array are even, odd and count them and print the information. 

(b) Write a program in C which reads a array of integers. Each element of the array is replaced by its square. Print back the array.

(a) Differentiate between call by value and call by reference parameter passing mechanism with the help of an example.
