Answer 1

#include 
#include 

static struct termios old, new;

void initTermios(int echo) {
    tcgetattr(0, &old);
    new = old;
    new.c_lflag &= ~ICANON;
    new.c_lflag &= echo ? ECHO : ~ECHO;
    tcsetattr(0, TCSANOW, &new);
}

void resetTermios(void) {
    tcsetattr(0, TCSANOW, &old);
}

char getch_(int echo) {
    char ch;
    initTermios(echo);
    ch = getchar();
    resetTermios();
    return ch;
}

char getch(void) {
    return getch_(0);
}

int main(void) {
    char c;
    printf("(getch example) please type a letter...");
    c = getch();
    printf("\nYou typed: %c\n", c);
    return 0;
}

Just copy these snippet and use it. Hope it helped
