void printDoubleArray(char * arrayName, double * arr, int length) { // 如果在函数内用sizeof来获得函数外传入的数组长度,会发现数组退化成了指针,获得的只是指针的长度 // printf("\nprintDoubleArray() loading...\n"); //printf("Double array length is: %d\n", length); //printf("双精度型...
cJSON_GetArrayItem内存泄露 stm32 最近遇到一个C++工程内存泄漏的问题,经过排查,发现原来是 map 的使用有问题,本文记录了排查的过程,并给出一个类似的工程代码。 起因 某日,运维反馈生产环境某台设备出现问题,经组长排查,有两个工程服务占用内存较多,出现 OOM 被 Linux 系统干掉了。其中一个是我接手的工程,竟达...

CArray::GetSize 傳回數位大小。 INT_PTR GetSize() const; 備註 因為索引是以零起始,因此大小大於最大索引 1。 呼叫此方法會產生與CArray::GetCount方法相同的結果。 範例 C++ CArray<CPoint, CPoint> myArray;// Add elements to the array.for(inti =0; i <10; i++) myArray.Add(CPoint(i,...
2) You can also use array name to initialize the pointer like this: p=var; because the array name alone is equivalent to the base address of the array. val==&val[0]; 3) In the loop the increment operation(p++) is performed on the pointer variable to get the next location (next ...
array name is the address of the first element of the array（3）指向数组的指针·将指针指向数组的首地址，再进行加减运算·对比标准的下标法访问数组元素，这种使用指针进行间接访问的方法叫作指针法·*（p+1）指向下一个元素(3) Pointer to array·Point the pointer to the first address of the array,...
