Date : September 12 2020, 03:00 PM
around this issue I want my C program to ask the user to type the name of the file he wants to open and print the contents of that file to the screen. I am working Dev-C.Can you describe how can i do this or can you make an example for me? , Here is a simple example to do that:
code :
FILE *fptr; 

char filename[100];
int c;

printf("Enter the filename to open \n"); 
scanf("%s", filename); 

// Open file 
fptr = fopen(filename, "r"); 
if (fptr == NULL) 
{ 
    printf("Cannot open file \n"); 
    exit(0); 
} 

// Read contents from file 
c = fgetc(fptr); 
while (c != EOF) 
{ 
    printf ("%c", c); 
    c = fgetc(fptr); 
} 

fclose(fptr);

This might help you How to give standard input to java program through files and take standard output to a file? , You can use OS redirection operators
code :
java Test < inputFile > outputFile
public class Test {
    public static void main(String[] args) throws IOException {
        for(int i; (i = System.in.read()) != -1;) {
            System.out.write((byte)i);
        }
    }
}

How would I redirect both Standard output and Standard input of a command to a text file in one line?

With these it helps How would I redirect both Standard output and Standard input of a command to a text file in one line, and would the Standard input of a command such as "ls" be "ls", and if I redirected the standard input of ls to a file, would these characters appear in the file? , To redirect both input and output, just use both redirections:
code :
command < inputfile > outputfile

Button that creates a <li> and adds user input on it

this one helps. The exercise says that my button (like a submit) must use the information set by user in input tag and create an li tag with the text as content. It was my first JavaScript class, so I'm still not familiarised with the syntax. , I guess this is what you want:
code :
(function () {
  document.querySelector('#add').addEventListener('click', function () {
    let input = document.querySelector('#text');
    let list = document.querySelector('#list'); 
    
    let item = document.createElement('li'); // create li node
    let itemText = document.createTextNode(input.value); // create text node
    
    item.appendChild(itemText); // append text node to li node
    list.appendChild(item); // append li node to list
    
    input.value = ""; // clear input
  });
})();
<div>
  <input id="text" type="text" />
  <button id="add">Add</button>
</div>

<ul id="list">
  <li>example item</li>
</ul>

I hope this helps . In a unix/linux environment, you can use pseudofiles /dev/stdin and /dev/stderr to achieve this, e.g. with bash shell:
