How to Restore the Default Action of a Signal with the Sigaction() Function in C Language In this example, we will show you how to restore the default action of a signal. To do this, we specify the signal in the “sig” input argument and set the SIG_DFL constant in the sa_handler...
In summary, fgets() reads a line from a stream safely into a buffer while taking care to prevent buffer overflows. This makes it very useful for line-oriented input handling in C programs. Examples of fgets() function in C Find examples of using the fgets() function in C Example 1: R...
We’ll show you the syntax, the input arguments, and the data types that each of them accepts. Then, we’ll apply what we learned in practical examples that include the code snippets and images which show the use of strcpy() in different cases and with different calling methods. Syntax o...
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 ...
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: "; ...
In C++ programming language, when we declare a function as inline, we suggest to the compiler that it should replace each function call instruction with the function's code, thereby reducing the overhead associated with function calls. However, it is important to note that the keyword inline is...

In C programming language, we can have a concept of Pointer to a function known as function pointer in C. In this tutorial, we will learn how to declare a function pointer and how to call a function using this pointer. To understand this concept, you sho
Here is main code in C language (main.c) : #include <stdio.h> extern void func(void); void f(void) { printf("\n being used within C code\n"); } int main(void) { func(); f(); return 0; } Please note that the C++ function is declared as extern here. ...
The function sprintf () is included in the standard input output library stdio.h. The header has to be declared at the beginning of your program, like this: #include <stdio.h> Examples of the sprintf () Function Let’s understand the sprintf () function better with the help of some ex...
