Now the question is: why is a dynamic array allocated on the stack at all? Furthermore, if I change only JBUF from POINTER to ALLOCATABLE, and I keep the rest of the code as is, then my test run fine, even with the original stack size (=10240 kbytes). This seems to imply that...
C語言沒有字串型別,而是用char array來模擬字串,由於本質是array,所以可以用pointer來表示字串,也因如此,造成C語言在操作字串時含其他語言差異甚大。 1/* 2(C) OOMusou 2007http://oomusou.cnblogs.com 3 4Filename : C_string.c 5Compiler : Visual C++ 8.0 / BCB 6.0 / gcc 3.4.2 / ISO C++ 6...

I generally find the undesirable temporaries by compiling with -S and looking for the dynamic allocation of the temporary, or the code which copies from the temporary to the final location. In ifort 9.x and 10.x, it was fairly common to create a temporary and store to it, ev...
4.Dynamic Allocation C語言 由於C語言是典型的靜態語言,使用array時必須事先定義好大小,這樣compiler才能做最佳化,若要讓C語言有動態功能,必須使用malloc()配合資料結構的linked list。 1 /* 3 4 Filename : DS_linked_list_simple.c 5 Compiler : Visual C++ 8.0 ...
