    Example of All Keyword in C language in Full Details

    auto: A 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.

    Some Others Languages Keywords 

    👉C++ Language Keywords

    👉Java Language Keywords

    👉Python Language Keywords 

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

    How To Use break Statement in C? 

    #include<stdio.h>

    int main()

    {

    for(int i=1;i<=10;i++)

    {

    if(i==5)

    {

    printf("break the 5 value of break\n");

    break;

    }

    printf("%d\n",I);

    }

    }

    *****OUTPUT*****
    1

    2

    3

    4

    break the 5 value of break

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

    #include<stdio.h>


    int main()


    {


    for(int i=1;i<=10;i++)


    {


    if(i==5)


    {


    printf("skip the 5 value of continue\n");



    continue;


    }


    printf("%d\n",i);


    }


    }


    *****OUTPUT*****


    1


    2


    3


    4


    skip the 5 value of continue


    6


    7


    8


    9


    10

    Syntax of 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<stdio.h>


    int main()


    {


    int x=2;


    switch(2)


    {

    case 1:


    printf("case one executed");


    break;


    case 2:


    printf("case two execuetd");


    break;


    case 3:


    printf("case three executed");


    default:


    printf("value are not match");


    }


    }


    *****OUTPUT*****


    case two executed

    *****OUTPUT*****


    The value of data:10

    do-while: A do-while loop is a very 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.

    }

    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 the long  number of value and float is used the floating-point value

    double data=13.75356354;

    float data=13.23;

    How To Use double and float in C?

    for(initiation;condition;increment)

    for(int i=1;i<=10;i++)

    How To Use for loop in C?

    int: A 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 of: 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: A static variable is 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;

    A typedef keyword can be used to long name to the small name change. typedef can be Using the short name of any long variables name.

    unionUnion 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

    student

    Data type var1;

    Data type var2;

    Data type var3;

    };

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