Arrays are a kind of data structure that can store a fixed-size sequential collection of elements of the same type.An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.LimitationsThe limitations of an array are explained below −An array which is formed will be homogeneous. That is, in an integer array only integer values can be stored, while in a float array only floating value and character array can have only characters. Thus, no array can have values of two data ...

A function is a self-contained block that carries out a specific well defined task.Advantages of functions in C language include −Reusability.The length of the program can be reduced.It is easy to locate and find any faulty function.It facilitates top-down modular programming.Top down design and structure chartsIt is a problem solving method in which a complex problem is solved by splitting into sub problems.Structure chart is a documentation tool that shows the relationships among the sub problems of a problem.The splitting of a problem into its related sub problems is the process of refining an algorithm. For example, performing arithmetic operations ... Read More

In C programming language, float is a short term for floating point.Floating point numbers are generally represented in the form of Institute of Electrical and Electronics Engineers (IEEE) format.The IEEE format uses a sign bit, a mantissa and an exponent for representing the power of 2.The sign bit denotes the sign of the number: a 0 represents a positive value and a 1 denotes a negative value.The mantissa represented in binary after converting into its normalized form. After normalization mantissa, the most significant digit is always 1.The exponent is an integer stored in unsigned binary format after adding a positive ... Read More

Loop control statements in C are designed to repeatedly execute operations until a specified condition is met. These Loops continue to run as long as the condition remains true. Loop control statements are used to repeat a set of statements. They are as follows − for loop while loop do-while loop For Loop in C The for loop in C allows us to repeat a set of statements a specified number of times. The for loop includes initialization, condition, and update statements within its syntax. It ... Read More

Expressions are evaluated by the ‘C’ compiler based on precedence and associativity rules.If an expression contains different priority operators, then the precedence rules are considered.Here, 10*2 is evaluated first since ‘*’ has more priority than ‘- ‘and ‘=’If an expression contains same priority, then associativity rules are considered i.e. left right (or right to left).

An expression is a combination of operators and operands.Operand is a data item in which operation is performed.An operator performs an operation on dataFor example; z = 3+2*1       z = 5Types of expressionsThe different types of expressions that are evaluated in C language are as follows −Primary expressions − The operand in this expression can be a name, a constant or any parenthesized expression. For example, c = a+ (5*b);Postfix expressions − In a postfix expression, the operator will be after the operands. For example, ab+Prefix expressions − In a prefix expression, the operator is before the operand. ... Read More

Fundamental Data Types in C Primary data types, also known as fundamental data types, are built-in data types in C. C compilers support four fundamental data types. They are as follows − Integer Character Floating-point Double precision floating-point Primary data types are the building blocks for storing and working with different kinds of data in C. Below, we will provide a brief overview of these data types. Integral Data Types Integral data types are used to store whole numbers and characters. These are the most important data types for programming because they define how data is represented in ... Read More

The programming languages are used to give instructions to the computer in a language which a computer can understand.Computer languages are classified into three types as follows −Machine languagesSymbolic languagesHigh level languagesMachine languagesComputer is a machine. Since, its memory can store only 1’s and 0’s, instructions must be given to the computer in streams of 1’s and 0’s i.e. binary code.These are easily understandable by the machine.Programs written in binary code can be directly entered into computer for execution and it is known as machine language.Advantages of machine language include −Execution is very fast.It is very difficult to write and ...

The algorithm is a step–by–step procedure that is helpful in solving a problem. If it is written in English-like sentences then, it is called PSEUDO CODE. It is a formula or a set of steps that solves a particular problem for a specified problem. Each step in the algorithm must be specified clearly. A programming algorithm is a process or formula for solving a problem. It involves a sequence of specified actions that describe how to perform a task, which the computer executes consistently. An algorithm follows a procedure consisting of inputs and produces a result, known as the output. ... Read More

C programming is a general-purpose, procedural, imperative computer programming language.Importance of C LanguageC is called as a robust language, which has so many built-in functions and operations, which can be used to write any complex program.Generally, we use to call C as a middle level language. Because, the ‘C’ compiler combines the capabilities of an assembly language with the features of a high-level language. Therefore, it is best for writing both system software and business packages.‘C’ Programs are efficient and fast.C is highly portable, that is, ‘C’ programs written on one computer can be run on another with little (or) ...
