What is C file data type? In C we have used Files. To handle files, we use the pointer of type FILE. So the FILE is a datatype. This is called the Opaque datatype.

Are files saved in RAM?
When you switch on the computer the data and instructions from the hard disk are stored in the RAM, e.g., when the computer is rebooted, and when you open a program, the operating system (OS), and the program are loaded into RAM, generally from an HDD or SSD. CPU utilizes this data to perform the required tasks.
What is array in C?
Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value. To create an array, define the data type (like int ) and specify the name of the array followed by square brackets [].
Which loop is faster in C language?
“Do-While loop is the fastest loop in C programming”.
2. Size of C structure is the total bytes of all elements of structure.
What does loop mean?
Definition of loop
(Entry 1 of 3) 1a : a curving or doubling of a line so as to form a closed or partly open curve within itself through which another line can be passed or into which a hook may be hooked. b : such a fold of cord or ribbon serving as an ornament. 2a : something shaped like or suggestive of a loop.
What is the conditional operator in C?
The conditional operator is a single programming statement and can only perform one operation. The if-else statement is a block statement, you can group multiple statements using a parenthesis. The conditional operator can return a value and so can be used for performing assignment operations.
The question mark operator, ?:, is also found in C++. Some people call it the ternary operator because it is the only operator in C++ (and Java) that takes three operands. If you are not familiar with it, it’s works like an if-else, but combines operators.
What are loops C?
What are Loops in C? Loop is used to execute the block of code several times according to the condition given in the loop. It means it executes the same code multiple times so it saves code and also helps to traverse the elements of an array.
What is continue in C programming?
The continue statement passes control to the next iteration of the nearest enclosing do , for , or while statement in which it appears, bypassing any remaining statements in the do , for , or while statement body.
What is header file in C?
A header file is a file containing C declarations and macro definitions (see Macros) to be shared between several source files. You request the use of a header file in your program by including it, with the C preprocessing directive ‘ #include ‘.
How do you write a break statement in C?
C Break and Continue
Example. int i; for (i = 0; i < 10; i++) { if (i == 4) { break; } printf(“%dn”, i);
Example. int i; for (i = 0; i < 10; i++) { if (i == 4) { continue; }
Break Example. int i = 0; while (i < 10) { if (i == 4) { break; }
Continue Example. int i = 0; while (i < 10) { if (i == 4) { i++; continue;
In Python, the break statement provides you with the opportunity to exit out of a loop when an external condition is triggered. You’ll put the break statement within the block of code under your loop statement, usually after a conditional if statement.
What is self keyword in Python?
self represents the instance of the class. By using the “self” we can access the attributes and methods of the class in python. It binds the attributes with the given arguments. The reason you need to use self. is because Python does not use the @ syntax to refer to instance attributes.
What is Python namespace?
Namespaces in Python. A namespace is a collection of currently defined symbolic names along with information about the object that each name references. You can think of a namespace as a dictionary in which the keys are the object names and the values are the objects themselves.
What is lambda function in Python?
Python Lambda Functions are anonymous function means that the function is without a name. As we already know that the def keyword is used to define a normal function in Python. Similarly, the lambda keyword is used to define an anonymous function in Python.
What is map in Python?
Map in Python is a function that works as an iterator to return a result after applying a function to every item of an iterable (tuple, lists, etc.). It is used when you want to apply a single transformation function to all the iterable elements. The iterable and function are passed as arguments to the map in Python.
What is lists in Python?
List. Lists are used to store multiple items in a single variable. Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are Tuple, Set, and Dictionary, all with different qualities and usage.
Python’s filter() is a built-in function that allows you to process an iterable and extract those items that satisfy a given condition. This process is commonly known as a filtering operation.
Is Python a keyword?
The “is keyword” is used to test whether two variables belong to the same object. The test will return True if the two objects are the same else it will return False even if the two objects are 100% equal.
What is zip in Python?
zip() in Python
It is used to map the similar index of multiple containers so that they can be used just using a single entity. Syntax : zip(*iterators) Parameters : Python iterables or containers ( list, string etc ) Return Value : Returns a single iterator object, having mapped values from all the. containers.
What are Conditional Statements in Python?
What are Conditional Statements in Python? Conditional Statement in Python perform different computations or actions depending on whether a specific Boolean constraint evaluates to true or false. Conditional statements are handled by IF statements in Python.
What are Python variables?
A Python variable is a symbolic name that is a reference or pointer to an object. Once an object is assigned to a variable, you can refer to the object by that name.
What is a loop in Python?
Looping means repeating something over and over until a particular condition is satisfied. A for loop in Python is a control flow statement that is used to repeatedly execute a group of statements as long as the condition is satisfied. Such a type of statement is also known as an iterative statement.
