Sorry about that. The photo was clear on my computer.

Code:

#include <stdio.h> 


int main () //start of program


{
 float tax=.08, total, sale; //signifies variables


    
printf("Please enter the sales amount."); //output to user to enter sales amount
    
        
scanf("%f",&sale);    //User inputs total sale amount
    
    
total=sale*tax;    //Assignment expression to calculate sales tax
    
    
printf("Your total sales tax is:%.2f\n", &total); //final output from calculations
    


return 0;          //end of program
}

Compile with warnings enabled.

Code:

$ gcc -Wall foo.c
foo.c: In function ‘main’:
foo.c:21:36: warning: format ‘%f’ expects argument of type ‘double’, but argument 2 has type ‘float *’ [-Wformat=]
   21 | printf("Your total sales tax is:%.2f\n", &total); //final output from calculations
      |                                 ~~~^     ~~~~~~
      |                                    |     |
      |                                    |     float *
      |                                    double

Your final printf is wrong, you don't normally have & in your printf statements unless you're using the %p format.

It's the whacked font that makes 'o' and '0' look identical which isn't helping either.

Thank you! @Salem
