How to create an interactive shell mode

Hey there! I'm experimenting with POSIX api and I want to create my own mini shell. I want my shell to open an interactive shell mode and be able to receive command input line by line from the kernel. I am not sure how to achieve this. If I am not mistaken, I read that I should be able to somehow link my shell to a /dev/ttyX or /dev/pts/X driver in "cooked mode" (my shell only receives input only after a user presses 'ENTER', not after every keypress)

Ive tried Googling for the solution, but its been ineffective. Im so confused, I don't even know how to look for a solution for this.

Here is the current code snippet of my program. (Excuse the bad programming) `initInteractiveMode` is meant to initialize interactive mode

```
#include <stdio.h>
#include <string.h>
#include <termios.h>

#define VERSION "0.0.1"

int parseArguments(int argc, char *argv[]);
void help();
void initInteractiveMode();

int main(int argc, char *argv[]) {
if (argc < 2) {
printf("shell\n");
return 0;
}

if (!parseArguments(argc, argv)) {
return 0;
}

initInteractiveMode(); // Initialize Interactive Mode

printf("Chloe's shell interactive mode enabled\n\n");

while (1) {
}

return 0;
}

// TODO: Open interactive mode
void initInteractiveMode() {

}

int parseArguments(int argc, char *argv[]) {
const char *arg = argv[1];
if (strcmp(arg, "-v") == 0 || strcmp(arg, "--version") == 0) {
printf("Chloe's shell, version %s\n", VERSION);
} else if (strcmp(arg, "-h") == 0 || strcmp(arg, "--help") == 0) {
help();
} else if (strcmp(arg, "interactive") == 0 || strcmp(arg, "i") == 0) {
return 1; // Enter interactive mode
} else {
printf("Invalid command\n\n");
help();
}

return 0;
}

void help() {
printf("Chloe's shell\n\n");
printf("\033[1mCommand:\033[0m shell [options]\n\n");
printf("List of options:\n");
printf("A simple shell for testing POSIX system calls\n");
printf("interactive\tEnter interactive mode\n");
printf("--help | -h\tDisplay help information\n");
printf("--version | -v\tDisplay version information\n");
}
```
