Thread: plotting a 2D tire using functions.

ok so heres the code i have so far but the code doesnt really do anything and I cant figure out
how to write the function to print the picture out on a rectangle space. help please.

Code:

int smlrad,bigrad;
int line,col;
int main (){
    
    printf("please enter your small radius.\n");
    scanf("%d",&smlrad);
    printf("please enter your big radius.\n");
    scanf("%d",&bigrad);
    
    
    for(line=-bigrad; line<=+bigrad; line++);{
for(col=-bigrad; col<=bigrad; col++);{
if (col^2+line^2<=1)
printf("+");
else if (col^2+line^2<=smlrad^2)
printf("$");
else if(col^2+line^2<=bigrad^2)
printf("+");
}
    
}   
    
system("pause");

This can be done via the distance formula which is essentially what has been mentioned.
