Invalid conversion from "const char*" to "char" error
<p>I wanted to post this because I was not really sure what issue I was having with a simple assignment statement.  I am doing a homework assignment that asks me to write structs and functions in a simple program to draw out shapes of ASCII characters.  Right now I am just trying to test the functions I have written, and I am trying to assign a value to the symbol element of a Circle struct just to test out the DrawShape function I wrote.  When I try to assign it a * char, I get an error message saying "error: invalid conversion from 'const char*' to 'char'".  I will put the whole code in, though it is very long and unfinished.  Any help with this would be appreciated. The problem I am getting is right in the beginning of the main at "circle1.char = '*' "</p>

<pre><code>#include &lt;iostream&gt;
#include &lt;math.h&gt;
#include &lt;cstdlib&gt;
using namespace std;

const int NUMBER_OF_ROWS = 26;
const int NUMBER_OF_COLUMNS = 81;
char drawSpace[NUMBER_OF_ROWS][NUMBER_OF_COLUMNS];

struct Point{
    int x;
    int y;
};

struct Circle{
    Point center;
    int radius;
    char symbol;
    bool buffer[NUMBER_OF_ROWS][NUMBER_OF_COLUMNS];
};

bool setCircleRadius(Circle &amp;b, int r);
bool setCircleCenter(Circle &amp;b, int x, int y);
bool moveCircle(Circle &amp;b, int x, int y);
void drawCircle (Circle b);
void lineChars(Line a);
void circleChars(Circle b);
void drawShapes();

int main() {
    Circle circle1;
    circle1.radius = 5;
    circle1.symbol = "*";
    circle1.center.x = 40;
    circle1.center.y = 10;

    drawCircle(circle1);

    return 0;
}
