Float is reading 0 regardless of input

[MTSchippert]

With the below program, whenever I enter an amount for bookcost, it reads 0. I've tried a few different things but I cannot seem to get it to use my input.
Around line 49 is where I ask for user input.
Any thoughts would be aweosme.

int main ()

    totalcost = (float) (totalcost+bookcost2);

    if (counter>0) {

    }
       
    
    
    //Totaling inputed values//
    //
    

    //Reiterating entered information//
    //
    
    
    //Counter for number of runs
    
}

I would switch this

 scanf(" %.2f", &bookcost);

into this

 scanf(" %f", &bookcost);

Works! Thanks,

I was looking at that but never thought about removing it for fear of someone entering more than two decimals. However, only the output needs to be truncated correct?

That is correct. If you want to be stringent about input for whatever reason, you should convert a string that is valid (such as "1.00") to a float, and reject the string otherwise. Precision is for output only.

Well i am not sure if understood the question(maybe my English are not good enough).Or say it in other words,or give me an example or wait for the other users to answer .

Also,welcome to the forum
