What is use of Scanf Function in C Language || 100% you don't know this type of working in programing language

 Uses Of "scanf" function in C language.

scanf Function:

        syntax of scanf:  scanf(const char *format, Object *arg(s))

        scanf if a function which is use for scan an input from user. scanf is a library function which in standard   input output library. scanf is some ware like as prinf function. scanf function scan a input from an user via standard input (keyboard).

       scanf  function is derived from  #include<stdio.h> library ( Standard input output libraries.)

Hear we will see some example of different type of value scan by scanf .

1) For integer Value scan.

Example :

#include<stdio.h>
#include<conio.h>
void main()
{
    int a;
    clrscr();
    printf("\nWelcome,CoderFact");
    printf("\nEnter a number : ");
    scanf("%d", &a);
    printf("Your entered a number is :  %d " , a);
    getch();
}

OUTPUT ::

we pass 5 as input form keyboard and we can see scanned number as 5.

hear we use %d to scan an integer value. %d is a specifier that specify that the number is an integer. simply %d is stand for decimal  integer number.

2) For character scan.

Example :

#include<stdio.h>
#include<conio.h>
void main()
{
    char a;
    clrscr();
    printf("\nWelcome,CoderFact");
    printf("\nEnter a name : ");
    scanf("%c", &a);
    printf("Your entered a name is :  %c " , a);
    getch();
}

OUTPUT ::

we pass 5 as input form keyboard and we can see scanned number as 5.

hear we use %d to scan an integer value. %d is a specifier that specify that the number is an integer. simply %d is stand for decimal  integer number.

Example :

#include<stdio.h>
#include<conio.h>
void main()
{
    char a[10];
    clrscr();
    printf("\nWelcome,CoderFact");
    printf("\nEnter a name : ");
    scanf("%s", &a);
    printf("Your entered a name is :  %s " , a);
    getch();
}

OUTPUT ::

Example::

#include<stdio.h>

#include<conio.h>

void main()

{

    float a;

    clrscr();

    printf("\nWelcome,CoderFact");

    printf("\nEnter a float number : ");

    scanf("%f", &a);

    printf("Your entered a number is :  %f",a);

    getch();

}

OUTPUT::
