calloc in c is another memory allocation function that is normally used for requesting memory space at run time for storing derived data types such as arrays and structures. While malloc allocates a single block of storage space...

A block of memory may be allocated using the function malloc in c. The malloc function reserves a block of memory of specified size and returns a pointer of type void. This means that we can assign it to any type of pointer. It...
Most often we face situations in programming where the data is dynamic in nature. That is, the number of data items keep changing during execution of the program. For example, consider a program for processing the list of...
We can access and assign values to the accessing structure members in a number of ways. As mentioned earlier, the members themselves are not variables. They should be linked to the structure variables in order to make them...
We use arrays structures to describe the format of a number of related variables. For example, in analyzing the marks obtained by a class of students, we may use a template to describe student name and marks obtained in various...
Variables in C differ in behavior from those in most other languages. For example, in a BASIC program, a variable retains its value throughout the program. It is not always the case in C. It all depends on the...
C permits nesting of function in c freely. main can call function1, which calls function2, which calls function3, ….. and so on. There is principle no limit as to how deeply functions can be nested. Consider the following...
Like the values of simple variables, it is also possible to pass the values of an array to a function. To passing arrays to function in C a one dimensional an array to a called function, it is sufficient to list the name of the...
Like variables, all functions in a C program must be declared, before they are invoked. A function declaration (also known as function prototype) consists of four parts. Function type (return type) Function name Parameter...
Definition of Function in C A function definition, also known as function implementation shall include the following elements 1. function name; 2. function type; 3. list of parameters; 4. local variable declarations; 5. function...
