You can utilize the following command at the command prompt to compile the code:

g++ winst.cpp -mwindows -o winst.exe
There are two controls in the code. Let us see at the static one. The class is, STATIC; this is the
second argument of the CreateWindowEx function. The name of the static control is, “First
Name”; this is the third argument of the function; this name occurs as the content display of the
static control. You have the WS_CHILD style signifying that it is a child window. The rest of the
arguments to the CreateWindowEx function are like those for the EDIT control. Keep in mind,
