Here, we are going to learn about thefclose() function of library header stdio.h in C language with its syntax, example/program. Submitted bySouvik Saha, on January 06, 2019 fclose() function in C Prototype: int
In the C Language, the required header for the ceil function is: #include <math.h> Applies To In the C Language, the ceil function can be used in the following versions: ANSI/ISO 9899-1990 ceil Example /* Example using ceil by TechOnTheNet.com */ #include <stdio.h> #include <math...
This code first opens the file example.txt in read mode. Then, it uses a while loop to read each file line using fgets(). Until fgets() returns NULL, indicating that the file’s end has been reached, the loop keeps going. Ultimately, the file is closed, and the program exits. Exam...

Example: int main(void) { // code to be executed return 0; } Library functions –These are preset functions that are already available in the C library. They perform particular tasks including mathematical computations, input/output activities, and string operations. In C programming, library fun...
Examples of ceil function in C++ Let us see different examples in getting to know the” ceil” functions: Example #1 Code: #include <iostream> #include <cmath> using namespace std; int main() { float x; int y; cout<<"Enter any float number: "; ...
Below is the syntax offork()function in C language: variable_name = fork(); Using fork() Function By usingfork()function, we can create a exact same copy of the calling process, this function returns the process id of own and this process id is known as child process id and if we ...
The example below showcases the implementation of an inline function in C++.Code Example:#include<iostream> using namespace std; // Use the keyword "inline" to define an inline function inline int sum(int a, int b) { // Definition of inline function return a + b; } int main() { ...

回调函数是做为参数传递的一种函数,在早期C样式编程当中,回调函数必须依赖函数指针来实现。 而后的C++语言当中,又引入了 std::function 与 std::bind 来配合进行回调函数实现。 标准库中有大量函数应用到了回调函数,其中 std::sort 就是一个经典例子。
