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...
If *InfoValuePtr is a Unicode string (when calling SQLGetInfoW), the BufferLength argument must be an even number; if not, SQLSTATE HY090 (Invalid string or buffer length) is returned.StringLengthPtr [Output] Pointer to a buffer in which to return the total number of bytes (excluding ...
If the application has specified a pointer to a row status array or a buffer in which to return the number of rows fetched, SQLFetch also returns this information. Calls to SQLFetch can be mixed with calls to SQLFetchScroll but cannot be mixed with calls to SQLExtendedFetch. For more ...
Applications should provide a valid pointer in the RowStatusArray argument; if not, the behavior of SQLExtendedFetch and the behavior of calls to SQLBulkOperations or SQLSetPos after a cursor has been positioned by SQLExtendedFetch are undefined....

In this example, we can use a function to print the elements of an array: #include<iostream> voidfunction(intarr[],intsize); intmain() { intarray[] = {1,2,3,4,5}; function(array,5); for(inti =0; i <5; i++) { std::cout << array[i] << std::endl; ...

char— Input must be of class char or a value that MATLAB can convert to a char, such as string. double— Input can be a numeric value of any precision. cell— Input must be a cell array. A user-defined class If you do not specify a class, then any class is allowed unless rest...
