Call by value

  • In call by reference, original value is modified because we pass reference (address).
  • Here, address of the value is passed in the function, so actual and formal arguments shares the same address space. Hence, value changed inside the function, is reflected inside as well as outside the function.

Call by value

  • In call by value, original value is not modified.
  • In call by value, value being passed to the function is locally stored by the function parameter in stack memory location. If you change the value of function parameter, it is changed for the current function only.
  • It will not change the value of variable inside the caller method such as main().

  • C Standard library functions or simply C Library functions are inbuilt functions in C programming.
  • The prototype and data definitions of the functions are present in their respective header files, and must be included in your program to access them.
  • If you want to use printf() function, the header file <stdio.h> should be included. For example,

Copy String Manually Without Using strcpy()

  • In this C Program we have to copy the string without using library functions.

  • Pattern programs in C print various patterns of numbers and stars. These codes explain how to create various patterns using C programming. The C programs involve usage of nested for loops (a for loop inside a for loop).
  • A pattern of numbers, star or characters is a way of arranging these in some logical manner or they may form a sequence. Some of these patterns are triangles which have special importance in mathematics.

Difference between data structure and database ?

Data Structure Database
Data Structure is about storing data
or handling data into RAM or Temporary Memory.		 Database is concept or tool which store & handle data at permanent memory location (Hard Drive).
Data structure is not permanent storage.
It is alive till the program is alive. But we can use the
different data structure to add data into database.		 We can use Database to store Data Structure containing process data at the end of any process .
Data structure is the memory. Database is Storage in computer.
Data structure is voltile memory. Database is non-volatile memory.

  • We want to convert hexadecimal number AB1c to binary. For this we will replace each hexadecimal digit to binary values using the above table:

Hexadecimal Number: A B 1 c
Binary Values: (1010) (1011) (0001) (1100)
So (AB1c)16 = (1010101100011100)2

Answer : NULL

  • We are incrementing the pointers p1,p2.
  • When it reached the end of the string, *p2 points to NULL.
  • We have lost the address of the starting position.

While calculating the x value, x & y values are post incremented. So, the values of x & y are added and then incremented i.e. x=56, y=36

While calculating the y value, x & y values are preincremented, so x & y values are incremented and then added i.e x=57, y=37.

What is the main difference between c and c++ ?
C C++
C is a structured programming language. C++ is an object oriented programming language.
C language is not in solving the real time problem. C++ works well in solving real time problem.
Polymorphism is not possible. Polymorphism is used in C++.
In C, malloc() and calloc() Functions are used for
Memory Allocation and free() function
for memory Deallocating.		 C++, new and delete operators are used for Memory Allocating and Deallocating.
Operator overloading is not possible in C. Operator overloading is one of the greatest Feature of C++.
No namespace Feature is present in C Language. Namespace Feature is present in C++ for avoiding Name collision.
scanf() function used for input and printf() function
used for output.		 Cin function used for input and Cout funtion used for output.
Polymorphism, Operator Overloading Concept is not
possible in C.		 Polymorphism, Operator Overloading Concept is the most important feature in C++.
C requires all the variables to be defined
at the starting of a scope.		 C++ allows the declaration of variable anywhere in the scope i.e at time of its First use.
Exception Handling is not present in C. Exception Handling is done with Try and Catch block.

Pick out the odd one out of the following malloc(), calloc(), free(), realloc() ?

  • free()

Explanation:

  • Here malloc(), calloc(), realloc() are the memory allocation function. whereas free() is used to free the memory which is allocated by the above function.
  • so the free() is odd term.

malloc()

  • The function malloc() reserves a block of memory of specified size and return a pointer of type void which can be casted into pointer of any form.
  • It allocates single block of memory

calloc()

  • calloc() allocates multiple blocks of memory each of same size and sets all bytes to zero.
  • It allocates space for an array elements, initializes to zero and then returns a pointer to memory.

realloc()

  • If suppose we assigned more or less memory than required, then we can change the size of the previously assigned memory space using realloc.

free()

  • The function free is used to deallocate or free the memory after the program finishes which was dynamically allocated in the program.
