Ncurses, Convert the int value to char pointer in C-CodePudding

I'm using Ncurses in C to create an input and output window. When the user types in something, I want to use mvwprintw() to display the string to the output window. I stored the return value of wgetch() in an array, how do I convert the int array to char pointer

/* cmd is an array already have the int value for the character,
  I declare it like char cmd[100], and store the int value return by wgetch() into 
  it*/
char realcmd[100];
for (int i = 0; i < 100; i  ) {
    if (cmd[i] == 0){
         realcmd[i] = '\0';
     }
     else{
         realcmd[i] = cmd[i]   0;
     }
}

This is how I convert the int array to char pointer, but I only get the first character. For example, if I type in " hello world", I only get 'h'.

CodePudding user response：

How do you call the function mvwprintw()?

Which format string to you use as fourth argument? It seems to me, that you use the char (%c) conversion qualifier instead of the string (%s) qualifier.

Try this:

mvwprintw(win, 0, 0, "%s", realcmd);

mvwprintw() use the same conversion qualifier as printf(). You can read this in the man page from mvwprintw().
