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: printf c float printf ( "%.6f" , myFloat ) ; Example 3: c printf float value I want to print a float value which has 2 integer digits and 6 decimal digits after the comma . If I just use printf ( "%f" , myFloat ) I'm getting a truncated value . I don 't know if this always happens in C, or it' s just because I'm using C for microcontrollers ( CCS to be exact ) , but at the reference it tells that % f get just th

Convey meaning through color with a handful of color utility classes. Includes support for styling links with hover states, too. Colors Colorize text with color utilities. If you want to colorize links, you can use the .link-* helper classes which have :hover and :focus states. < p class = " text-primary " > .text-primary </ p > < p class = " text-secondary " > .text-secondary </ p > < p class = " text-success " > .text-success </ p > < p class = " text-danger " > .text-danger </ p > < p class = " text-warning bg-dark " > .text-warning </ p > < p class = " text-info bg-dark " > .text-info </ p > < p class = " text-light bg-dark " > .text-light </ p > < p class = " text-dark " > .text-dark </ p > < p class = " text-body " > .text-body </ p > < p class = &

Answer : Try using the passive command before using ls . From FTP client, to check if the FTP server supports passive mode, after login, type quote PASV . Following are connection examples to a vsftpd server with passive mode on and off vsftpd with pasv_enable=NO : # ftp localhost Connected to localhost.localdomain. 220 (vsFTPd 2.3.5) Name (localhost:john): anonymous 331 Please specify the password.

Answer : Testing is doubting. More seriously, let me answer you. In Angular, your components are handled by a module. When you use Material dialogs and snackers, you actually use a feature of the CDK, which is called Portal . This allow you to create your components dynamically. But when you do so, you have to add them to the entryComponents of your module. You did it in your module, so you should also do it in your tests. The syntax is TestBed .configureTestingModule(...) .overrideModule(BrowserDynamicTestingModule, { set: { entryComponents: [YourComponent] } }); there are two places at which this is supposed to be done....entry components and also at declarations(while configuring your testing module).... TestBed .configureTestingModule({ declarations: [YourComponent], }) .overrideModule(BrowserDynamicTestingModule, { set: { entryComponents: [YourComponent] } }); If someone struggling to find BrowserDynamicTestingModule just use BrowserModule
