Thread: sequence issue in coding...

Code:

#include <stdio.h>
main()
{
    float price, new_price;
    char code;
    
    printf("Enter the price: ");
    scanf("%f", &price);
    
    printf("Enter the pricing code: ");
    scanf("%c", &code);


    if(code=='A')
    {
        final_price=price*0.5;
        printf("New discounted price is %.2f\n", final_price);
    }
    else if(code=='B')
    {
        final_price=price*0.6;
        printf("New discounted price is %.2f\n", new_price);
    }
    else if(code=='C')
    {
        final_price=price*0.7;
        printf("New discounted price is %.2f\n", new_price);
    }
    else if(code=='D')
    {
        final_price=price*0.9;
        printf("New discounted price is %.2f\n", new_price);
    }
    else if(code=='E')
    {
        final_price=price;
        printf("New discounted price is %.2f\n", new_price);
    }
    else
    {
        final_price=price;
        printf("Invalid pricing code. \n");
    }

}

if i place:
printf("Enter the pricing code: ");scanf("%c", &code);
before
printf("Enter the price: ");scanf("%f", &price);
the program runs, but if i put it this way, it doesn't, please help me out here, thanks.

When you type in a "price" and press enter, the "price" is stored - but the newline (from pressing enter) is waiting in the input buffer.

Then, when you attempt to scan a single character, it reads the newline waiting in the buffer, making it appear as if the second "scanf()" is skipped.

More information, as well as solutions, in the FAQ: FAQ > How do I avoid a "dangling" newline when reading single character user input? - Cprogramming.com

I didn't actually try running your program because it can't compile (the variable "final_price" is not declared anywhere).

so sorry, the "final_price" was changed to "new_price", i must have paste the older code, my bad... And thank you for your help
