C Programming

Pointers give greatly possibilities to ‘C’ functions which we are limited to return one value. With pointer parameters, our functions now can process actual data rather than a copy of data . In order to modify the actual values of variables, the calling statement passes addresses to pointer parameters in a function. Functions Pointers Example…

What is Pointer in C? The Pointer in C, is a variable that stores address of another variable. A pointer can also be used to refer to another pointer function. A pointer can be incremented/decremented, i.e., to point to the next/ previous memory location. The purpose of pointer is to save memory space and achieve…

What is a Function in C? Function in C programming is a reusable block of code that makes a program easier to understand, test and can be easily modified without changing the calling program. Functions divide the code and modularize the program for better and effective results. In short, a larger program is divided into…

C File management A File can be used to store a large volume of persistent data. Like many other languages ‘C’ provides following file management functions, Creation of a file Opening a file Reading a file Writing to a file Closing a file Following are the most important file management functions available in ‘C,’ function…

What is Storage Class in C? A storage class represents the visibility and a location of a variable. It tells from what part of code we can access a variable. A storage class in C is used to describe the following things: The variable scope. The location where the variable will be stored. The initialized…

What is Switch Statement in C? Switch statement in C tests the value of a variable and compares it with multiple cases. Once the case match is found, a block of statements associated with that particular case is executed. Each case in a block of a switch has a different name/number which is referred to…

What is Loop in C? Looping Statements in C execute the sequence of statements many times until the stated condition becomes false. A loop in C consists of two parts, a body of a loop and a control statement. The control statement is a combination of some conditions that direct the body of the loop…

What is a Conditional Statement in C? Conditional Statements in C programming are used to make decisions based on the conditions. Conditional statements execute sequentially when there is no condition around the statements. If you put some condition for a block of statements, the execution flow may change based on the result evaluated by the…
