What does the data type of a pointer mean?
The actual data type of the value of all pointers, whether integer, float, character, or otherwise, is the same, a long hexadecimal number that represents a memory address.
The only difference between pointers of different data types is the data type of the variable or constant that the pointer points to..
What are the first and second arguments of Fopen?
A character string containing the name of the user & the second argument is the mode.A character string containing file pointer & the second argument is the mode.A character string containing the name of the file & the second argument is the mode.All of above.None of these.
What is file and example?
A collection of data or information that has a name, called the filename. Almost all information stored in a computer must be in a file. There are many different types of files: data files, text files , program files, directory files, and so on. … For example, program files store programs, whereas text files store text.
What is data file in C?
A data file is a computer file which stores data to be used by a computer application or system, including input and output data. A data file usually does not contain instructions or code to be executed (that is, a computer program).
What is the data type of file?
A FILE is a type of structure typedef as FILE. It is considered as opaque data type as its implementation is hidden. We don’t know what constitutes the type, we only use pointer to the type and library knows the internal of the type and can use the data. Definition of FILE is in stdio although it is system specific.
What are different types of files?
6 Different Types of Files and How to Use ThemJPEG (Joint Photographic Experts Group) … PNG (Portable Network Graphics) … GIF (Graphics Interchange Format) … PDF (Portable Document Format) … SVG (Scalable Vector Graphics) … MP4 (Moving Picture Experts Group)
What are the four common types of files?
The four common types of files are document, worksheet, database and presentation files.
How many types of files are there in C?
When dealing with files, there are two types of files you should know about: Text files. Binary files.
What is file structure C?
FILE structure in C Programming C Provides smart way to manipulate data using streams. In stdio.h header file FILE structure is defined. FILE structure provides us the necessary information about a FILE or stream which performs input and output operations.
Which is data type of file pointer is Mcq?
Explanation: fp is a pointer of FILE type and FILE is a structure that store following information about opened file. 2. Which of the following mode argument is used to truncate? Explanation: None.
What is FILE * fp?
File pointer is declared as FILE *fp. Where, ‘fp’ is a file pointer. fopen() function is used to open a file that returns a FILE pointer. Once file is opened, file pointer can be used to perform I/O operations on the file. fclose() function is used to close the file.
What is a string in C language?
Advertisements. Strings are actually one-dimensional array of characters terminated by a null character ‘\0’. Thus a null-terminated string contains the characters that comprise the string followed by a null.
What is pointer with example?
A pointer is a variable that stores the address of another variable. Unlike other variables that hold values of a certain type, pointer holds the address of a variable. For example, an integer variable holds (or you can say stores) an integer value, however an integer pointer holds the address of a integer variable.
How do you declare a pointer?
Pointers must be declared before they can be used, just like a normal variable. The syntax of declaring a pointer is to place a * in front of the name. A pointer is associated with a type (such as int and double ) too.
What are the two most common filing techniques?
You have two basic methods: straight filing and draw filing. Here’s the difference between the two: Straight Filing: The first and most basic filing technique is called straight-filing, and involves pushing the file lengthwise across the work, making contact only on the forward stroke.
What are the 3 types of files?
Stores data (text, binary, and executable).
What are the two types of files?
There are two types of files. There are Program files and Data Files. Program files, at heart, can be described as files containing software instructions. Program files are then made up by two files called, source program files and executable files.
What is Pointer and its types?
A pointer is nothing but a memory location where data is stored. A pointer is used to access the memory location. There are various types of pointers such as a null pointer, wild pointer, void pointer and other types of pointers. Pointers can be used with array and string to access elements more efficiently.
How are files classified?
Files are classified according to their cross-sectional shapes, the form of the cutting edges, and the coarseness of the cut (i.e., the number of teeth per inch or centimetre).
What are the classification of filing?
Filing and classification systems fall into three main types: alphabetical, numeric and alphanumeric. Each of these types of filing systems has advantages and disadvantages, depending on the information being filed and classified. In addition, you can separate each type of filing system into subgroups.
What is file and types of file in C?
Compiling C programs requires you to work with five kinds of files: Source files: These files contain function definitions, and have names which end in . … They are used to allow source code files to access externally-defined functions. Header files end in . h by convention.
