This tutorial is designed for software programmers with a need to understand the C programming language starting from scratch. This C tutorial will give you enough understanding on C programming language from where you can take yourself to higher level of expertise.
Most programming languages including C support the for keyword for constructing a loop. In C, the other loop-related keywords are while and do-while. Unlike the other two types, the for loop is called an automatic loop, and is usually the first choice of the programmers.
In C language, the assignment operator stores a certain value in an already declared variable. A variable in C can be assigned the value in the form of a literal, another variable, or an expression.
A switch statement in C simplifies multi-way choices by evaluating a single variable against multiple values, executing specific code based on the match. It allows a variable to be tested for equality against a list of values.
File handling in C is the process of handling file operations such as creating, opening, writing data, reading data, renaming, and deleting using the C language functions. With the help of these functions, we can perform file operations to store and retrieve the data in/from the file in our program.
C enumeration (enum) is an enumerated data type that consists of a group of integral constants. Enums are useful when you want to assign user-defined names to integral constants. The enum keyword is used to define enums.
The C programming language provides a keyword called typedef to set an alternate name to an existing data type. The typedef keyword in C is very useful in assigning a convenient alias to a built-in data type as well as any derived data type such as a struct, a union or a pointer.
A union is a special data type available in C that allows to store different data types in the same memory location. You can define a union with many members, but only one member can contain a value at any given time.
An average of set of numbers is their sum divided by their quantity. It can be defined as − average = sum of all values / number of values Here we shall learn how to programmatically calculate average. Algorithm Algorithm of this program is very easy − START Step 1 → Collect integer values in an array A of size N Step 2 → Add all values of A Step 3 → Divide the output of Step 2 with ...
To use the pointers in C language, you need to declare a pointer variable, then initialize it with the address of another variable, and then you can use it by dereferencing to get and change the value of the variables pointed by the pointer.
