Problem with directing output to text file

[jonathan123456]

I have this program below, it works fine until it comes to the while loop, it asks me if I want to direct the output to a text file and the program doesnt let me enter a character in this case either yes or no. Can someone tell me whats wrong. Thanks

#include <stdio.h>
#include <stdlib.h>
#define carrots 1.09
#define artichokes 2.05
#define onions 1.15


int main(void)

    char ans;
    char result;

    float discount = 0;
    float shippingCost = 0;
    printf("Welcome to YourGreens.com!\n\n");
    printf("Our choices & prices for today are as follows:\n\n");
    printf("A.Carrots: 1.09 EUROS per KG\n");
    printf("B.Artichokes: 2.05 EUROS per KG\n");
    printf("C.Onions: 1.15 EUROS per KG\n\n");
    do
    {
    printf("Enter 'a' for carrots, 'b' for artichokes, 'c' for Onions or 'q' to Checkout:\n");
    scanf("%c",&ans);
    switch(ans)
        {
            case 'a': printf("Enter amount of Carrots in KG:\n");
            scanf("%f",&nocarrots);
            totalcarrots = totalcarrots + (nocarrots * carrots);

            scanf("%f",&noartichokes);

    weight = weight + (carrotsweight + artichokesweight + onionsweight);

    printf("TOTAL WEIGHT OF GROCERIES IS: %.2f KG\n\n",weight);


    if ( totalall >= 100 )
    {
        discount = totalall*0.05;
        totalall = totalall - ( totalall * 0.05);
        printf("For orders over 100 euros a 5% discount is given\n");
        printf("Your new total is: %.2f EUROS",totalall);
    }


    if ( weight <= 5 )
    {
        shippingCost = 6.5;

        printf("For orders of 20KG and exceeding, the shipping costs will be 14.00 EUROS and an added 0.50 EUROS per KG\n");

    }


    printf("\n\n");
    printf("Do you want to transfer output to a text file? y/n? \n");
    scanf("%c",&result);


    while ( result != 'n')

scanf() tends to leave the newline character into the stream. scanf("%c") reads that newline and the user never gets the chance to give his answer. To work around that, use scanf(" %c"), note the extra space before the percent sign. This tells scanf to ignore all whitespace characters.
