一、用delete 删除数组中元素(少用) 说明：delete: 只是被删除的元素变成了 undefined ，即数组长度不变 //定义数组 var array=["aa","dd","cc","aa"]; //方法1：delete删除数组元素 delete array[1]; //输出结果 : ["aa",undefined,"cc","aa"] getArray(array); 输出结果： 　　　　aa 　　　　undefined 　　　　cc 　　　　aa 二、用splice删除数组的元素 说明：该方法会自动改变原始数组，即每用一次splice(i,1)数组长度自动减1 var array = ["aa","dd","cc","aa"]; //方法2：删除数组元素 array.splice(1,1); //输出结果：["aa","cc","aa"] getArray(array); 输出结果： 　　　　aa 　　　　cc 　　　　aa 来源： https://www.cnblogs.com/yanl55555/p/11997657.html

Trying to compile a load of .c files (1) The files compile ok, using cc cc -Wall -Wextra -Wunreachable-code -ggdb -O0 *.c (2) Then, I need to make a static library from the final output, to use in a c++ program. So I do: ar cru liborientdb-c.a *.o (3) Works ok. However when I come to compile the c++ program testme.cpp that includes the library in line #1 (line 1 of testme.cpp) #include "liborientdb-c.a" Compile step: cc testme.cpp i get this error: liborientdb-c.a:117:22: error: stray '\3' in program liborientdb-c.a:117:263: warning: null character(s) ignored [enabled by default] liborientdb-c

I have a very very simple C++ file as follows that I'm compiling on Solaris 5-10 with the CC compiler. Here is the source code in my file myTest.C: #include <map> std::map<int, bool> myVar2; I would like to first run the CC pre-processor on this file, examine the pre-processed file, and then compile that pre-processed file into an object file. I call this "indirect-compiling". To do this, I do the following: % CC -P -o myFile_indirect.i myFile.C % CC -c -o myFile_indirect.o myFile_indirect.i I would also like to compile this file without a separate pre-processing step as is normally done. I

In Woocommerce I try to customize the code from this thread to add a custom email as "CC" email address in customer completed order email notification: /** * Function adds a BCC header to emails that match our array * * @param string $headers The default headers being used * @param string $object The email type/object that is being processed */ function add_cc_to_certain_emails( $headers, $object ) { // email types/objects to add cc to $cc_email = get_user_meta( $user_id, 'order_cc_email', true ); // MY CUSTOM CODE $add_cc_to = array( 'customer_completed_order', // Customer Processing order
