即使未使用malloc,數組是如何創建的? #include <stdio.h>
#include <stdlib.h>
int main() {
int n,i,*ptr,sum=0;
printf("Enter number of elements: ");
scanf("%d",&n);
printf("Enter elements of arr
在以下代碼中的可分配數組,我試圖通過首先分配較大尺寸的臨時數組buf(:),複製的a(:)內容以buf(:),然後使用move_alloc()到增加的a(:)長度從buf數組描述符複製到a: program main
implicit none
integer, allocatable :: a(:), buf(:)
allocate(a(2))
a =
