Change color of stdin in C (like in fish shell)

Question

I'm trying to write a simple shell. I just want to change the color of the text the user types in which in the future will be used for stuff like syntax highlighting. Can I use the standard library for this or do I need to use something like ncurses. Its pretty easy to change the output color. Is there a similar solution?

Thanks in advance.

I think you can find this here https://stackoverflow.com/questions/3219393/stdlib-and-colored-output-in-c — Robert, Oct 29 '20 at 05:42
that question is for output. does it work the same way for imput — rushdabs, Oct 29 '20 at 05:58
If i remember properly, you use the sequence to setup the color of the terminal. No mater input or output. So, if you setup the red color, if you do a scanf, the color should be red. — Robert, Oct 29 '20 at 06:06
@Robert Thanks I'll try that. Do you know where I can find that? — rushdabs, Oct 29 '20 at 06:21
Find what? The sequences to setup the color are listed in the link Robert posted. — Gerhardh, Oct 29 '20 at 08:45
@Gerhardh Sorry about that. I didn't read it carefully. Thanks for pointing it out — rushdabs, Oct 29 '20 at 09:03

Have a look at here and here.

I think this Sample Code should help you,

#include<stdio.h>

int main()
{
    int num;
    printf("%s", "\033[92mEnter Number : \033[34m");
    scanf("%d", &num);
    printf("%s", "\033[0m");
    return 0;
}

Above coe will print Enter number : in green and typing number in blue,

Note : Make sure that your terminal supports ANSI escape color code see here for windows 10.
