Please help have trouble my with porgram

I having some trouble with my if statement would someone help me outmain.cpp

Code:

#include<stdio.h>

void main()
{ 
    char instruc[2];
    const  double artichokes=1.25,beets=0.65,carrots=0.89,discount=0.05;
    double totalartichokes,totalbeets,totalcarrots,totalpound=0,shipping,input,totalcost,pounds;
    bool keepgoing =true;// a bolean data type

        printf("\n");
        printf("                           ABC Mail Order Grocery\n\n");
        printf(" Type 'a' for artichokes, 'b' for beets, 'c' for carrots , and 'q' to exit sale.\n\n");
    //frist we need an infinite loop
    while (1){// 1 is always logicaly true
        //next we will read an instruction from stdio

        scanf("%s %lf",instruc, &input);
            switch(instruc[0])
        {
           case 'a':
               pounds+=input;
               totalartichokes=artichokes*input;
               printf(" Artichokes  %lf\n", totalartichokes);
             break;
           case 'b':
              pounds+=input;
              totalbeets=beets * input;
              printf(" beets  %lf\n", totalbeets);
             break;
           case 'c':
                pounds+=input;
                totalcarrots=carrots * input;
                printf(" carrots %lf\n", totalcarrots);
             break;
          case 'd':
                totalpound+=pounds;
                totalcost= totalartichokes+totalbeets+totalcarrots ;
                printf("\n Total Weight is %.2lf",totalpound);
                printf("\n SubTotal is $%.2lf \n",totalcost);
                if(totalcost>= 100)
                    totalcost=totalcost-(.05*totalcost);
                if(totalpound >= 5)
                totalcost=3.50+totalcost;// $3.50 shipping
                shipping=3.50;
                if(totalpound <= 5 )
                if(totalpound>=20)
                totalcost=10.00+totalcost;// $10.00 over 5pounds ,but under 20pounds shipping
                shipping=10.00;

                if(totalpound < 20)
                totalcost=8.00+(.10*totalpound)+totalcost;
                shipping=8.00+(.10*totalpound); 
                break;
          case 'q':
                keepgoing = false;
                break;
                {printf(" Shipping and handling is $%.2lf\n",shipping);
                printf("\n Total is $%.2lf \n",totalcost);}
        
        }// end switch(instruc[0])
   
    
                    
        if (keepgoing==false)break; // exit the infinite loop


        }//end while (1) loop
}//end main

Which one. Elaborate. Only thing I can see is that

Code:

                if(totalpound <= 5 )
                if(totalpound>=20)
                totalcost=10.00+totalcost;// $10.00 over 5pounds ,but under 20pounds shipping

Will never evaluate to true. Use extra braces around if statements if you are unsure.

I am sorry I don't have time to really look at your code, but a quick pass reveals a lack of braces. They are free! Use them to space out your code and make it look more organized.

What is the if statements error? Also, this is a C++ board and that is coded in C.
Please print the logical error you have encountered. it will be easier to tell you what you are doing wrong.

> #include<stdio.h>
> void main()
1. main returns an int
2. Apart from your single bool, there is very little C++ in this C program. Which language are you learning?

I'm new to C++. Just started taken class at Cincinnati State .

As I'm sure you are aware, no code is executed after you've breaked from a switch statement:

Code:

          case 'q':
                keepgoing = false;
                break;
                {printf(" Shipping and handling is $%.2lf\n",shipping);
                printf("\n Total is $%.2lf \n",totalcost);}
        
        }// end switch(instruc[0])

The code in red will never be executed.

Thanks for the help I've my final code ready for tomorrows class

Code:

        printf("\n");
        printf("\n");

        }//end while (1) loop
}//end main

here my program is running

1. Make a safe backup

Not too bad - now you can polish it a bit by tidying up the code formatting
- making sure all the blocks of code are indented consistently for example.

> while (1)
Try while ( keepgoing )
