C++ || Operators with c++

Operators with c++: 



 

In the previous tutorial we learnt about arithmetic and assignment operator with c++. 

Now let's learn other operators! 

We already know there are six types of operators! 

 

 Now let's learn about Logical operator, Bitwise operator, Relational operator, and other operators. 

1.logical operators: 

Logical operators are used to check whether an expression is true or false. If the expression is true, it returns 1 whereas if the expression is false, it returns 0. 

Operator 

Example 

Meaning 

&& 

expression1 && expression2 

Logical AND. 
True only if all the operands are true. 

|| 

expression1 || expression2 

Logical OR. 
True if at least one of the operands is true. 

! 

! expression 

Logical NOT. 
True only if the operand is false. 

In C++, logical operators are commonly used in decision making. To further understand the logical operators, let's see the following examples, 

 

OUTPUT: 

 

2. Relational Operator: 

Relational operator is also known as comparison operator. 

Comparison operators are used to compare two values (or variables). This is important in programming, because it helps us to find answers and make decisions. 

The return value of a comparison is either 1 or 0, which means true (1) or false (0). These values are known as Boolean values, and you will learn more about them in the Booleans and If. Else chapter. 

In the following example, we use the greater than operator (>) to find out if 5 is greater than 3: 

 

 

A list of all comparison operators: 

Operator 

Name 

Example 

== 

Equal to 

x == y 

!= 

Not equal 

x! = y 

> 

Greater than 

x > y 

< 

Less than 

x < y 

>= 

Greater than or equal to 

x >= y 

<= 

Less than or equal to 

x <= y

C programming | Printf and scanf ||

By Programming codester
  Programming Codester   Printf and scanf function with C language:   We learnt fundamentals of C in previous tutorial.   If you haven't read the previous tutorial, I mentioned the link below here.   So now it's time to learn print and scanf function.   Both printf and scant functions are inbuilt library functions, defined in stdio.h (header file).   Printf ;   The printf functions create and output strings formatted at runtime . They are part of the standard C library. Additionally, the printf functionality is implemented in other languages (such as Perl). These functions allow a programmer to create a string based on a format string and a variable number of arguments.   In shot Printf function is used to print any statements in C language.   The syntax of printf function:   Printf (“any statement you want”);   Example syntax of pr intf :   Printf (“programming codester ”);    Scanf :   In ...

  Programming codester   C programming   Structure   on user’s demand I bring the tutorial of structure in c language!   So first find the error from this code: #include<stdio.h> void main() { printf("hello"); return 0; } If you want to see my other tutorial of c programming I will mention all link at the end of this tutorial. So, stay tuned!   So guys lets start structure with C!   If you want to learn structure, you have to knowledge of datatypes!   So, first we learn about datatypes.   DATATYPES:   There are 2 types of data type :   1.Primary datatype:   In this datatype float, int, char, void, etc. Are the best examples.   2. Secondary Data type:   In secondary data type there are 2 types of secondary data types!                     1] Derived Data type   ( Array , pointer)   2] User defined Dat...

  PROGRAMMING CODESTER     In the previous tutorial we studied the basics of programming language and also learnt about flow chart and algorithm and about interpreter and compiler.   So, we start with c programming in this tutorial.   In the technical world many languages are available for talking to computers like   c, c ++, java, java script, python, c#, and many more.   But for beginners and those who are new to this stream c programming is very easy to learn and it's very useful to learn other languages also so we can also say that c language is the base of programming language.    C programming was created in the 1972s by Dennis Ritchie and remains very widely used and influential.     In this tutorial we will study about:   F u n d a m e n t a l s o f c p r o g r a m m i n g   Application of c programming   Structure of c programming   First basic program “hello world ”.   Let's begin! ...

Programming Codestrer   Importance of c programming   { embedded programming }   Q & A SESSION   So, hello my wonderful people!   In this tutorial I tried to cover basic and most asked question by students, beginners and programmers.   -----------------------------------------------------------------------------------------------------------   1.Whenever students start coding, there is always a question in the mind of students which language should be first?   -> So, my answer is you should start with c programming because c programming is a very basic and easy language to learn coding and programming.   -----------------------------------------------------------------------------------------------------------   2. Why C is the base of programming language?   -> The C language is a high-level, general-purpose programming language. It provides a straightforward, consistent, powerful interface for programming systems ...

C++ || string with c++ || Part - 1

By Programming codester
  Programming codester   C++ || String with c++       [PART-1]   in previous tutorial we learn about operators.   So now it's time to learn the concept of string with object-oriented programming with c++ .   Question of the day: Which memory storage is widely used in PCs and Embedded Systems? a) EEPROM b) Flash memory c) SRAM d) DRAM STRING WITH C++: -   Strings are used for storing text.   A  string   variable contains a collection of characters.   So, let's learn with example about string.   Syntax:   string variable = “your string ”;   EXAMPLE:   string blog =  "programming codester " ;   In this example variable is blog and string are programming codester .   To use strings, you must include an additional header file in the source code, the  <string>   library.   Example of string with object-oriented programming with c++ .     So, you s...

  PROGRAMMING CODESTER   What is compiler and interpreter?   Hello wonderful people!   So, in our previous blog we learnt about flow charts and algorithms .   So now we will be studying types of computer languages and also learning what compiler and interpreter.   Types of computer languages:   Machine level language OR Low-level language   It is the language of 0’s and 1’s.   Computers directly understand this language.   Assembly language   It uses short descriptive words (MNEMONIC) to represent each of the machine language   instructions.   It requires a translator knows as assembler to convert assembly language into machine language   so that it can be understood by the computer.   Examples: 8085 Instruction set   Higher level language   It is a machine independent language.   We can write programs in English like manner and therefore easier to learn and use.   Examples: C, C++, JAV...

c++|operators with c++|variables||

By Programming codester
Programming codester   Object oriented programming with c++   Operators and variables with c++   In the previous tutorial, we learnt about data types and user input cin .   Question of c programming What is the out of following program? #include <stdio.h> int main ( ) { int i = 10 ; int * p = & i ; printf ( "%d \n " , * p ++ ) ; } AANSWER:10 Now we start a new tutorial!   We will learn about different operators in c++ ( oop )   Variables:   Variables are containers to store any data.   i.e., to store any biscuits, we use boxes.   for example, int is used for integers, float is used for floating numbers, char is used for any character.   So variable is the container who stores our values and data.   Variable scope:   Local variable: are declared inside the braces of any function and can be accessed from there.   Global variable: are declared outside any function and...
