why is the loops not working ?

i am using an Indefinite for loop
Quote:
for( (;;))

but it does not stop looping so i tried to use while loop and with the while loop when
Quote:
(bra>2)

it still print[quote] ("do u want to add more y or n")/quote]which i do not want it to do so.
and when ( bra ==1) it does not allow me to enter Y or N option it skips the scanf() do u have any idea why it does that.
and what is the correct thing to do pls

with the for loop dis is the code
Code:
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <string.h>

void create_new_stock(void);
void display_stock(void);
void sales(void);
void modify(void);
void Additem(void);
void Viewitems(void);
void Viewcategory(void);
void Editcategory(void);
void Edititems(void);
void Edit(void);
void Deleteitem(void);
void Deletecategory(void);
void PrintBeeper(void);
void CreateFile(void);
void DeleteFile(void);
void sel();

char cate[20];

void create_new_stock()
{
   int bra;
   char ans;

scanf("%s",cate);

scanf("%d",&bra);
for(;;)

puts("Enter Selling price for(box)");
scanf("%lf",&S_prx_Blk);

puts("Enter selling price for unit");
scanf("%lf",&S_prx_u);

if (bra<=1)

puts("do u want to add more y or n");
scanf("%c",&ans);

if(tolower(ans) == 'n')          
break;

}
getchar();
}


void display_stock()
{

   
}

void sales()
{

   
   }

void modify()
{

   

}

int main()
{
char sele; // seletion of data

puts(" Welcome to my sales Program");
puts("<1> \t Create a new stock ");
puts("<2> \t Display Stock");
puts("<3> \t Sales");
puts("<4> \t Modify");
puts("<5> \t exit");

puts("Enter selection");
scanf("%c",&sele);


switch (sele)

break;
case '4':
modify();
break;

with the while loop this is the code
