Format Specifier For Double Code Example


Example 1: format specifier fro float in printf

printf("%0k.yf" float_variable_name)  Here k is the total number of characters you want to get printed. k = x + 1 + y (+ 1 for the dot) and float_variable_name is the float variable that you want to get printed.  Suppose you want to print x digits before the decimal point and y digits after it. Now, if the number of digits before float_variable_name is less than x, then it will automatically prepend that many zeroes before it.

Example 2: what are format specifiers

it is used during taking input and out put  Int ("%d"):  Long ("%ld"): Char ("%c"):  Float ("%f"):  Double ("%lf")  example:  char ch = 'd'; double d = 234.432; printf("%c %lf", ch, d);  char ch; double d; scanf("%c %lf", &ch, &d);

Example 3: double data type format in c

%lf you can try

Example 4: printf format specifiers c

/* printf example in C */ #include <stdio.h>  int main() {    printf ("Characters: %c %c \n", 'a', 65);    printf ("Decimals: %d %ld\n", 1977, 650000L);    printf ("Preceding with blanks: %10d \n", 1977);    printf ("Preceding with zeros: %010d \n", 1977);    printf ("Some different radices: %d %x %o %#x %#o \n", 100, 100, 100, 100, 100);    printf ("floats: %4.2f %+.0e %E \n", 3.1416, 3.1416, 3.1416);    printf ("Width trick: %*d \n", 5, 10);    printf ("%s \n", "A string");       return 0; }   //*******  Characters: a A Decimals: 1977 650000 Preceding with blanks:       1977 Preceding with zeros: 0000001977 Some different radices: 100 64 144 0x64 0144 floats: 3.14 +3e+000 3.141600E+000 Width trick:    10 A string

530 Valid Hostname Is Expected When Setting Up IIS 10 For Multiple Sites

Answer : Solution 1: When configured with two or more hostnames, the correct virtual host name and username must both be sent in the username by the ftp client. Separate the site name and user with the vertical line symbol: | www.example.com|MyUser So, in your FTP Client use this for the username: ftp.telefonievergelijken.nl|tv_ftp Solution 2: It appears that you're attempting to connect to the FTP site using a hostname which is not currently configured in any of the bindings to the FTP site within IIS. I base this only on the error output from Filezilla which you have included, as you have censored the hostname (even in example form) from the output, so there isn't much more to go on. You'll need to configure a binding on the FTP site which matches the hostname you are using to connect to the FTP site (whether that be from Filezilla or any other FTP client). EDIT: From your updated post information, I notice that your bindings for the FTP site are indeed in...

C Perror Example

Defined in header <stdio.h> void perror ( const char * s ) ; Prints a textual description of the error code currently stored in the system variable errno to stderr . The description is formed by concatenating the following components: the contents of the null-terminated byte string pointed to by s , followed by ": " (unless s is a null pointer or the character pointed to by s is the null character) implementation-defined error message string describing the error code stored in errno , followed by '\n' . The error message string is identical to the result of strerror ( errno ) . Parameters s - pointer to a null-terminated string with explanatory message Return value (none). Example # include <stdio.h> int main ( void ) { FILE * f = fopen ( "non_existent" , "r" ) ; if ( f == NULL ) { perror ( "fopen() failed" ) ; } else { fclose...

Android - ImageView With Rounded Only One Corner

Image
Answer : You can use the Material Components Library. With the version 1.2.0-alpha03 there is the new ShapeableImageView . Just use in your layout: <com.google.android.material.imageview.ShapeableImageView app:srcCompat="@drawable/..." ../> And in your code apply the ShapeAppearanceModel with: float radius = getResources().getDimension(R.dimen.default_corner_radius); imageView.setShapeAppearanceModel(imageView.getShapeAppearanceModel() .toBuilder() .setTopRightCorner(CornerFamily.ROUNDED,radius) .setBottomLeftCorner(CornerFamily.ROUNDED,radius) .build()); You can use this library and put your ImageView inside the Layout https://github.com/JcMinarro/RoundKornerLayouts and can set the radius for specific corners like this containerLayout.setCornerRadius(2f, CornerType.ALL); containerLayout.setCornerRadius(2f, CornerType.BOTTOM_LEFT); Other choices public final enum class CornerType private constructor() : kotli...
