How can I create an executable that keeps running and shows up in task manager, but does nothing? I need it for a program, I can use every language, or if it already exists it's better.
Thanks.

Answer 1

Here is a C code to do the job, you can use the thread sleep method to decrease the CPU load
#include<stdio.h>
int main()
{
char a;
while((a=getchar())!='z')// to quit the program when z is pressed
{
}
return 0;
}

Answer 2

Create a file with .cmd extension and write this into that file:
:BEGIN
GOTO BEGIN
You can double click on it, and call it from any programming language you want with this like code:
system("/path_to_your_code/your_file.cmd");

Answer 3

Here's a good example in C#
using System;
using System.Threading;
class Program {
static void Main() {
while(true) {
Thread.Sleep(100); // So we don't spam the CPU too much
}
}
}
Another example for an program you actually could quit without too much hassle.
It just waits for you to press Enter. :)
using System;
class Program {
static void Main() {
Console.ReadLine();
}
}
