If you have any doubts, please give me comment...

#include<stdio.h>

int main(){

    double price, best_price;

    int best_sup_no = 1, supplier_no = 1;

    char another_sup = 'Y';

    while(another_sup=='Y' || another_sup=='y'){

        printf("What is the price for supplier #%d?\n", supplier_no);

        scanf("%lf", &price);

        if(supplier_no==1)

            best_price = price;

        if(best_price>price){

            best_price = price;

            best_sup_no = supplier_no;

        }

        supplier_no++;

        printf("Is there another supplier to consider?\n");

        scanf("\n%c", &another_sup);

    }

    printf("Supplier #%d had the best price at $%g.\n", best_sup_no, best_price);

    return 0;
