In this tutorial you will learn about Single character input output, String input and output, Formatted Input For Scanf, Input specifications for real number, Input specifications for a character, Printing One Line, Conversion Strings and Specifiers, Specifier Meaning.
One of the essential operations performed in a C language programs is to provide input values to the program and output the data produced by the program to a standard output device. We can assign values to variable through assignment statements such as x = 5 a = 0 ; and so on. Another method is to use the Input then scanf which can be used to read data from a key board. For outputting results we have used extensively the function printf which sends results out to a terminal. There exists several functions in ‘C’ language that can carry out input output operations. These functions are collectively known as standard Input/Output Library. Each program that uses standard input / out put function must contain the statement.
Managing Input and Output Operations
In this tutorial you will learn about Expressin in C programming language - Arithmetic Expressions, Evaluation of Expressions, Precedence in Arithmetic Operators, Rules for evaluation of expression, Type conversions in expressions, Implicit type conversion, Explicit Conversion and Operator precedence and associativity,
Arithmetic Expressions
An expression is a combination of variables constants and operators written according to the syntax of C language. In C every expression evaluates to a value i.e., every expression results in some value of a certain type that can be assigned to a variable. Some examples of C expressions are shown in the table given below.

In this tutorial you will learn about Operators, Arithmetic operators, Relational Operators, Logical Operators, Assignment Operators, Increments and Decrement Operators, Conditional Operators, Bitwise Operators and Special Operators.
An operator is a symbol which helps the user to command the computer to do a certain mathematical or logical manipulations. Operators are used in C language program to operate on data and variables. C has a rich set of operators which can be classified as

A C language programmer has to tell the system before-hand, the type of numbers or characters he is using in his program. These are data types. There are many data types in C language. A C programmer has to use appropriate data type as per his requirement.
