There are many interesting answers to th

variable of the corresponding position, producing a string that the caller wants.Formatting numeric stringsOne of the most common applications of sprintf is to print integers into strings, so sprintf can be substituted for most occasionsItoaSuch as:The integer 123 is printed into a string stored in S.sprintf (S, "%d", 123); Generate "123"You can specify a width, insufficient left fill space:sprintf (S, "??", 123, 4567); Generated: "123 4567"Of course, you can also align Left:sprintf (S, "%-8d",

, because the browser is not clear whether Folderorfile is a folder or file, so cannot automatically add slashes. At this point, the browser does not have a slash directly access to the address, the server responds to a redirect, resulting in an unnecessary handshake.4.

printf will%f the output by double type, that is, the parameter float type will be converted to double type in the output.But now is not%f, of course, using%f to show the correct results. So I guess, printf is the float type read into the data are automatically converted to double type, and then%f double processing, and we this is%d, so the display of float converted to a double type of low 4 bytes.Verify this idea: #include "stdio.h"int main (int argc, char* argv[]){Double F = 5.01;int *p = (i
