In terms of safety, functions in the C standard library also have an associated error code. In the case offread(), an error code of 0 indicates that the required number of items (in bytes) was not read. This code can be used to handle errors related to corrupt or incomplete data sets...
When it comes to solving problems in computer programming, there are many techniques available. One of these isrecursion, which is a process that involves calling a function within itself. This article will explore how to implement recursive functions in the C programming language. We will discuss...

The toupper function C programming converts a lowercase letter to a corresponding uppercase letter. In the default “C” locale, a lowercase letter is any of:a b c d e f g h i j k l m n o p q r s t u v w x y z. which translates respectively to:A B C D E F G H I...
using different language-specific tools, but in C++, all of them are known as callable objects. Callable objects can be traditional functions, pointers to the functions, lambda expressions,bindcreated objects, classes that overload()operator, andstd::functiontype objects defined in<functional>header...
1. Call C functions from C++ In this section we will discuss on how to call C functions from C++ code. Here is the C code (Cfile.c): #include <stdio.h> void f(void) { printf("\n This is a C code\n"); } The first step is to create a library of this C code. The follow...
Modern C++ has a lot of useful functions thanks to its evolution from the C language. One of them was thegets()function that we use to get string inputs and that we were able to use in C++11 or earlier. In C++14, thegetsfunction was removed, whilefgetsor other input functions remain...
It is then named KtoF in the "Name Manager" which allows the user to pass values to the custom function like this: =KtoF(B4) where B4 is a cell reference to cell B4. The use of custom functions makes it easier to reuse complex formulas across worksheets. By creating a custom ...
This C++ Sleep tutorial will discuss the Sleep Function in C++ & see how to put a thread to sleep. We will also learn about the other functions viz. usleep.
The SORT function can sort a multi-column cell range, however, you can only choose one column to sort by. Use the SORTBY function if you need to sort by two or more columns. Formula in cell E3: =SORT(B3:C7, 2) SORT(array, [sort_index], [sort_order], [by_col]) ...
