中文含义:sizeof使用数组作为参数时会返回int*大小(指针的字节数),即使用sizeof测试数组类型的参数大小时得到的并不是整个数组的字节数,而是指针的字节数(数组被退化为指针使用sizeof) 原因是数组作为参数传给函数时,是传给数组首个元素的地址,而不是传给整个的数组空间,因此 sizeof(arr)这句话会报错...
perhaps you should change your prototypevoidtoBase(intnum,intto,intresult[],int*size); the size of the array is on `i' Dec 23, 2019 at 6:44pm Shervan360(184) @ne555 Thank you but we don't know what is the size of arr in toBase function. The size of the arr is not fixed. ...
例如:在C语言中通过 `malloc` 和 `free` 申请和释放,Java语言由垃圾回收期(GC)收回。```cint* create_array(int size) { int* arr = (int*)malloc(size * sizeof(int)); // 堆分配 return arr; // 返回指针,内存生命周期延续}int main() { int* myArray = create_array(10); free(myArray)...
1. 创建变量 在C语言中,变量是用于存储数据的内存位置。 c #include <npp-naipu.com.cn> int main() { int a = 10; // 创建一个整数变量并初始化 float b = 3.14; // 创建一个浮点数变量 char c = 'A'; // 创建一个字符变量 printf("a = %d, b = %.2f, c = %c\n", a, b, c)...
(sizeof(int) * 3);// 3个数嘛,3个int f(把答案写入temp); ans[(*returnSize)] = temp;// 这两个都是一阶指针 (*returnSize)++; } // returnColumnSizes是二阶指针, (*returnColumnSizes)是一阶指针 // 有(*returnSize)行就malloc(*returnSize)个元素 (*returnColumnSizes) = (int *)malloc(...
// Maximum array size is Integer.MAX_VALUE h = Math.min(i, Integer.MAX_VALUE - (-low) -1); } catch( NumberFormatException nfe) { // If the property cannot be parsed into an int, ignore it. } } high = h; cache = new Integer[(high - low) + 1]; ...

我正在开发一个仅使用指针修改数组数据的程序。我正在尝试返回索引,其中arrayix==0。然而,我一直被困在无限循环中。我做错了什么?int* end = arr + size; while(begin<end){ return*begin; }} 浏览2提问于2019-04-30得票数 2 2回答 即使条件计算为true,代码也会跳过循环 、 我不能让程序的这一部分进入...

int func(int aa[4]) { return sizeof(aa);} 返回值为几何?? 偶遇此问题,顺便在标准中找到了相关描述。 C99 A declaration of a parameter as‘‘array of type’’ shall be adjusted to ‘‘qualified pointer to type’’, where the typequalifiers (if any) are those specified within the [ and...
