Change color per Character ncurses

Hello,
I am writing a program that reads a file and prints each character of a file in different randomly chosen color. I am using ncurses for that,
But the problem is that i cannot change color per character basis, rather it changes color of full screen each time while refreshing instead of character,

Code:

#include<ncurses.h>
#include<math.h>
#include<string.h>
#include<stdlib.h>

int main(int argc, char *argv[])
{
    int row, col, x, y, main_Color, r, g, b, c;
    char ch;
    
    FILE *fp;

    if(argc != 2)
    {
        printf("Usage : %s <file>", argv[0]);
        exit(1);
    }

    fp = fopen(argv[1], "r");
        
    if(fp == NULL)
    {
        perror("\nCannot open file\n");    
        exit(1);
    }

    initscr();
    getmaxyx(stdscr, row, col);
    start_color();
    c = 1;

    while((ch = fgetc(fp)) != EOF)
    {
        getyx(stdscr, y, x);

        if(y == (row - 1))
        {
            printw("<-- Press any key -->");
            getch();
            clear();
            move(0,0);
        }

        main_Color = rand()%8;
        r = rand()%1001;
        g = rand()%1001;
        b = rand()%1001;

        init_color(main_Color, r,g,b);
        
        //c is for random color pair index...
        init_pair(c, main_Color, COLOR_BLACK);
        chgat(1, A_NORMAL ,c, NULL);
        printw("%c", ch);
        refresh();
        c++;
    }

    refresh();
    getch();

    fclose(fp);
    endwin();
}

Am i suppose to use something else than chgat, also im not getting black background....

EOF is an int, so ch needs to be an int (confusing, I know).

I can't help you with ncurses, but I can show you how to do this with conio.h. Can you use conio.h, instead of ncurses?

What exactly are you trying to make with the char's being printed?

I know eof is int, it's just macro for int value, what im trying to achieve that i get every character of different(random) color..

OK, one more time. ch should be an int.

Can you use conio.h, instead of ncurses?

Actually im following a tutorial of ncurses, not sure about conio.h, all i now it's clrscr() and getchar()(guess im right)..

"all i now" ??

My fingers are dying to keyboard "Speak'em inglesh, mooch?", but don't worry - I won't let them.

Keep working on that tutorial. Someone may come along and know the answer.
