Union is a user defined data type which contains variables of different data types. Or we can say that, union is collection of dissimilar type of elements or data. The concept of union is taken from structure so the syntax of union is same as structure. Union can be defined using keyword “union” as shown …
C Enumeration or Enumerated Data Type C enumeration is a user defined data type which consists of a list of names and each name corresponds to an integral constant. It increases the program readability as names are easy to read and maintain. Enumerated data type can be defined in C using “enum” keyword. The syntax …
We declare a pointer to integer, pointer to character or pointer to array. Similarly we can declare a pointer to function or a function pointer. Same as like variables, functions also have some address in memory. C Function Pointer A function pointer is a pointer that contains the address of a function. It can be …
When we declare a pointer we specify its type which will be same as the type of the variable whose address the pointer will contain. For example if we will declare an integer pointer then it can contain the address of an integer variable only. Take below example. int *p,a; char b; p=&a; //valid p=&b; …
While doing programming we may come across a situation when the number of data items keeps on changing during the program execution. For example, we have made a program that stores the details for employees in a company. The list of employees keeps changing as new employees join or old employees leave the company. When …
Read: File Handling in C – Part 3 In the last tutorial I told you about the file copy program using file input output functions. From the last two tutorials you must have noticed that the base of the program is same for all but we are making just simple twist to do our desired task. …
Read: File Handling in C – Part 2 In the last tutorial I told you about the program to calculate the number of spaces, blanks, tabs and characters. You might have noticed that I have used the similar logic of file reading program in that tutorial. Today I will continue the quest of learning file input …
Read: File Handling in C – Part 1 In the last tutorial I told you about the basic file input output functions. If you are reading this tutorial by skipping the last tutorial then I would strongly recommend you to read that tutorial first. So today I will tell you one program that will count all …
