A Computer is used for performing many Repetitive types of tasks The Process of Repeatedly performing tasks is known as looping .The Statements in the block may be Executed any number of times from Zero to Up to the Condition is True. The Loop is that in which a task is repeated until ...
What should I do if garbled characters are displayed in HiLog information? How do I analyze fault logs (such as JSCrash, CppCrash, and Appfreeze)? How do I locate the fault when the application crashes? Which one is recommended for logging, HiLog or console? How do I set the dom...
The statement cin>>a[i]; in the for loop inputs various elements of array a corresponding to each value of index i, which are then displayed using another for loop. When i=0 then in the statement cin>>a [i]; i is replaced with 0 and value for 1st element of array is inputted....
In the below example, we will create a StringStream object as we have created in the previous section. We will then use a buffer, a while loop, and a for loop to print the content of the StringStream object in the form of arrays of string. The code will check if the stream is ...

Instead, it should be re-written to explicitly zero-initialize sum before the loop: /* *a : Pointer to an array of signed integers n : Number of elements in the array */ int func(int *a, unsigned int n) { int sum = 0; for (unsigned int i = 0; i < n; i++) { sum +=...
There are other reasons that might cause the compiler to reorder certain instructions. For example, the compiler might reorder nested loops so that the code exhibits better locality of reference (this optimization is called loop interchange). Another example is to reduce the costs of register spilli...
Sending (This use of auto_ptr could be considered overkill, but the technique is useful in more complex code, or in general, when you want to take the possibility of errors seriously): std::auto_ptr<CString> p(new CString("whatever")); ...
