Example of All Keyword in C++ language in Full Details

auto

An auto keyword makes an automatic variable like:

auto int data;

This statement suggests that data is a variable of storage class auto and datatype int.

Automatic variables are local functions, they are also called local variables. so it is called the auto variable.

break

A break keyword statement terminates the loop immediately. The break statement ends the for a loop when the condition is false.

Some Others Languages Keywords 

👉C Language Keywords

👉Java Language Keywords

👉Python Language Keywords 

How To Use break Statement in C++?

#include<iostream> using namespace std; int main() { for(int i=1;i<=10;i++) { if(i==5) { cout<<"break the 5 value of break statement"; break; } cout<<i<<"\n; } } *****OUTPUT***** 1 2 3 4 break the 5 value of break statement

continue Statement: A continue statement skips the value of the current iteration of the loop. continue statement is a print next iteration.

How To Use continue statement in C++?

#include<iostream> using namespace std; int main() { for(int i=1;i<=10;i++) { if(i==5) { cout<<"skip the 5 value of continue statement"; continue; } cout<<i<<"\n; } } *****OUTPUT***** 1 2 3 4 skip the 5 value of continue statement 6 7 8 9 10

Switch Case: A switch statement is used to check the condition. The switch statement is a very most useful statement. switch statements are a multiple condition check using a switch case.  

Syntax switch Statement 

switch(expression) {     case '1':     //case one execute ;     break;     case '3':     //case three execute;     break;     default:     //no case match is default case is executed; }

How To Use switch statement in C++?

#include<iostream> using namespace std; int main() { int x=2; switch(2) {                case 1:                               cout<<"case one executed";                               break;                case 2:                               cout<<"case two execuetd";                               break;                case 3:                               cout<<"case three executed";                default:                               cout<<"value are not match";                } } *****OUTPUT***** case two executed

char: A char keyword defines the character value

Example:

char grade='A';

HowTo Use of char keyword?

#include<iostream> using namespace std; int main() { char grade='A'; cout<<"Student garde value:"<<grade; } *****OUTPUT***** Student grade value:'A'

const: A const identifier can be declared a constant value using the const keyword. the constant value can not be changed.

const int data = 10;

How To Use of const keyword?

#include<iostream> using namespace std; int main() { const int data=10; cout<<"The value of data:"<<data; } *****OUTPUT*****  The value of data:10

do-while: A do-while loop is a very most useful loop. do-while loop used the repeat the value. when they do while loop the first time executes in the program given the condition.

Syntax do-while loop

do { //statement; increment/decrement; } while(condition); }

How To Use do-while loop?

#include<iostream> using namespace std; int main() { int i=1; do {                cout<<" "<<i;                i++; } while(i<=10); } *****OUTPUT***** 1 2 3 4 5 6 7 8 9 10

double and float: double and float Keywords are used for declaring floating type value. double keywords are used for the long number of values and float is used for the floating-point value.

double data=13.75356354;

float data=13.23;

How To Use double and float

#include<iostream> using namespace std; int main() { double data=687537332; float d=53.2364; cout<<"value of double number:"<<data<<"\n"; cout<<"value of floating number:"<<d; } *****OUTPUT***** value of double number:687537332.000000 value of floating number:53.236401

if and else: An if-else statement is used in the decision-making condition. if the statement executes the condition is true. otherwise else statements are executed. when condition false.

Syntax of if-else statement 

if(condition) { //statement;  } else { //statement; }

How To Use of if-else statement

#include<iostream> using namespace std; int main() {                int age;     if (age<=18)     {         cout<<"You can play the PUBG Game";   }   else   {                cout<<"You can not play the PUBG Game";   }     return 0; } *****OUTPUT***** You can play the PUBG Game

enum: An enum is named integer constants. enum is a user-defined data type. enum is an Enumeration.

Syntax of enum

enum  enum_name{value1,value2,value3....value n};

How To Use of enum keyword 

#include<iostream> using namespace std; enum year { Jan,Feb,mar,api,may,June,July,Aug,sep,Oct,Nov,dec}; int main() { enum  year data; data=June; cout<<"value of june:"<<data; } *****OUTPUT***** value of june:5

extern: An extern keyword is used external linking outside of the file.

for: A for loop can be Using C Language. it is the very most useful loop. Because for loop in an initiation condition and increment/deferment only one line. so for loop is the most useful loop.

Syntax of for loop

for(initiation;condition;increment) for(int i=1;i<=10;i++)

How To Use of for loop

#include<iostream> using namespace std; int main() { for(int i=1;i<=10;i++) { cout<<" "<<i; } } *****OUTPUT***** 1 2 3 4 5 6 7 8 9 10

goto: The goto statement is a jump statement control of the program to another label of the program.

int: An int keyword is used the integer type value of the c Language.

return: The return keyword terminates the function and returns the value of the c program.

size: A size of keyword has used the size of data.

register: A register keyword is used the quick access the data.it is very fast to retrieve the data from the computer. Because value stored the register.

static: Static variables are not reclaimed. They keep their value. On re-entry to the block, the variable will have its old value.

struct: A struct keyword is used for declaring a structure. A structure can behold the variables of different types with only a single name.

Syntax of structure

struct student{     char name[80];      float marks;      int age; }s1, s2;

typedef: The C++ programming language provides a keyword called typedef, which you can use to give a type a new name. A typedef keyword can be used to long name to the small name change. typedef can Use the short name of any long variables name.

union: Union is a data type in C++ programming that allows different data types to be stored in the same memory locations. A union is used for grouping different types of variables under a single name. union is stored the single value stored. otherwise other value garbage value in the variables.

Syntax of union

union student {  Data type var1; Data type var2; Data type var3; };

void: void keyword meaning nothing value the use. the void return type of the c++ program.

volatile: A volatile keyword is used for creating volatile objects. It can be used the change the value of hardware memory.
