C program help me plz?

I am trying to do a programm that will ask the user to enter how many items they are buying after they enter how many items they are buying i want them to input each price, i think i have that so far. then i want to add each item to give tehm a total of their purchases but i dont know how to do it, and also i dont know why i have to use this for, someone was helping me previous so i dont know what that means. thanks again


#include%26lt;stdio.h%26gt;


main()


{


int i, items;


float sum, item_price, total;


char dummy;





printf("How many items are you buying today? ");


scanf("%i", %26amp;items);





for (i = 0; i %26lt; items; i++)


{


printf("Enter the price?");


scanf("%f",%26amp;item_price);


sum += item_price;








}














scanf("%c", %26amp;dummy);


}

C program help me plz?
//we need this line in order to be able to use the input and output


//functions (printf, scanf)


#include %26lt;stdio.h%26gt;





main()


{


//here, we declare the variables we want to use later on


int i, items;


float sum, item_price, total;


char dummy;


//add \n for a newline after the text


printf("how many items are you buying today?\n");


//%d means, that a decimal integer will be read from the commandline


scanf("%d", %26amp;items);


//because you only ever add to sum, you have to initialize it to zero


// so the program knows what the value should be before anything is added





sum = 0;





for(i=0; i %26lt; items; i++)


{


//more \n for more fun in life (actually only more linebreaks)


printf("\nEnter the price?\n");


scanf("%f", %26amp;item_price);


sum += item_price;


}





//here you should probably tell the customer how much he has to pay


printf("\n final sum: %f\n", sum);





//this is probably so the program will wait for a keystroke before


//quitting


scanf("%c", %26amp;dummy);


}
Reply:Get rid of the last scanf() because you are done. You only need to print the sum (use printf() -- look up how to format the data)





Can I make a suggestion? You really need to comment your code with your design before you start cutting the code. For example, right before the printf("How many ....), put


/*from the user, get the number of items*/





Before the loop, put


/* for the number of times indicated by items, get the price of each item */





then after the scanf


/*compute the total price for all items */





If you had done something like that, you would have known that you are done and the only thing left to do is print out the total.





FYI: All code-toads want to jump in and start coding. The good ones design first. It saves LOTS of time and headaches.
