How to compile c in xcode?

Do you have the correct includes for these functions?

Under the linking section of your project, you want to add Other linker flags : -lncurses.

Here is example code that is a combination of using this 2010 post, and an example from (7. input functions) from the NCURSES Programming Howto site. It compiles cleanly, and runs as it should in the Terminal. It does not launch Terminal from within Xcode and run the code though.

#define WORLD_WIDTH 50

#define WORLD_HEIGHT 20

int main(int argc, const char * argv[]) {

WINDOW *Win;

int offsetx, offsety;

char mesg[] = "Enter a string: ";

char str[80];

u_long row, col;

initscr();

refresh();

offsetx = (COLS - WORLD_WIDTH) / 2;

offsety = (LINES - WORLD_HEIGHT) / 2;

Win = newwin(WORLD_HEIGHT,

WORLD_WIDTH,

offsety,

offsetx);

box(Win, 0 , 0);

wrefresh(Win);

getmaxyx(stdscr,row,col);

mvprintw(row/2.0, (col-strlen(mesg))/2.0, "%s", mesg);

/* print the message at the center of the screen */

getstr(str);

mvprintw(LINES - 2, 0, "You Entered: %s", str);

getch();

delwin(Win);

endwin();

return 0;
