How can I put spaces in c

I want to put spaces in printf("%c",player.symbol);

spaces should be equal to the user input value in the following

printf("Next Move [1-%d]: ", game.pathlength);
scanf("%d", &player.location);

suppose player.symbol = V and user input Next Move: 8 i.e player.location =8 then the output should be like this: (8 spaces)V i.e, there must be 8 spaces before V.

How can I do that?

You can printf() an arbitrary number of spaces by controlling the variable width field character * in the following way:

void print_spaces(int n)
{
    printf("%*s", n, "");
}

So you print an empty string in a field of size the number of spaces you request it to have.

First, things to know from the printf manual:

The field width

An optional decimal digit string (with nonzero first digit) specifying a minimum field width. If the converted value has fewer characters than the field width, it will be padded with spaces on the left ... Instead of a decimal digit string one may write "*" ... to specify that the field width is given in the next argument

With that in mind to achieve the left space padding you require the code would be:

printf("%*c", player.location+1, player.symbol);

This says that the minimum width of the print is player.location+1. Since the player.symbol is a single character that means there will be player.location of space padding.
