for some reason this program refuses to compile, all the errors seem to occur on the &quot;Dsicount&quot; function when i can`t see any, any comments ideas would be greatly appreciated #include <stdio.h>

//funtion prototypes
void Cost_of_Purchase(float *pcost); //enter price of items
float Discount(float *pcost); //discount using required percentage
void Output_Bill(float,float); //output final values
void HoldScreen(void);

#define disc_1 = 0.08;
#define disc_2 = 0.10;
#define Limit = 100;



void main (void)
{
//declare variables
float cost;
float discounted_amount;

Cost_of_Purchase(&cost);
discounted_amount = Discount(&cost);
Output_Bill(cost, discounted_amount);
Holdscreen();

}


//input costs
void Cost_of_Purchase(float *pcost)
{
float price;
float cost;
int qty;

puts(&quot;Enter the following for item required&quot;);
printf(&quot;\tPrice of item&quot;);
scanf(&quot; %d&quot;, price);
printf(&quot;Quantity required&quot;);
scanf(&quot; %d&quot;, qty);
cost = qty * price;
}

//discount
float Discount(float *pcost)
{
float amount;
if (*pcost <= Limit)
amount = disc_1 * *pcost;
else
amount = disc_2 * *pcost;
return amount;
}

//output relavant amounts
void Output_Bill(float cost, float discounted_amount)
{
float discounted_cost;
discounted_cost = cost - discounted_amount;
printf(&quot;Cost of goods purchased....%10.2d&quot;, cost);
printf(&quot;Amount of discount....%10.2d&quot;, discounted_amount);
printf(&quot;Cost of goods purchased....%10.2d&quot;, discounted_cost);
}

void HoldScreen(void)
{
printf(&quot;\n\n\tPress ENTER to finish&quot;);
fflush(stdin);
getchar();
}


 
Your define section is the problem. You should change it as follows:

#define disc_1 0.08
#define disc_2 0.10
#define Limit 100

If you say: #define disc_1 = 0.08; then wherever disc_1 is met by the compiler, it is replaced with = 0.08; which you don't really want.

NOw it says that there is an illegal else without matching if!! i`m sure this is right below



float Discount(float *pcost)
{
float amount;
if (*cost <= Limit)
amount = *pcost * disc_1;
else
amount = *pcost * disc_2;
return amount;
}
