i tried Indefinite for loop (
for (;;)but it does not stop looping so i use while loop and with the while loop it prints the condition statement which i know it is within the loop that is why it outputs it .when i get it out i can not use the if statement
with the for loop dis is the code
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <string.h>
#include <ncurses.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();
double u_prx = 0.0;
double total=0.0;
double G_total=0.0;
double amut_b=0.0;
double amut_u=0.0;
double S_prx_Blk=0.0;
double S_prx_u=0.0;
double T_amut_blk=0.0;
double T_amut_u =0.0;
double qty_sold = 0.0;
int T_qty_bulk =0;
int T_qty_u =0;
int G_T_qty_bulk=0;
int G_T_qty_u=0;
int qty_u= 0;
int qty_left = 0;
int qty_bulk = 0;
char cate[20];
char iname[20];
char code[6];
void create_new_stock()
{
int bra;
char ans;
printf("Enter Category ");
scanf("%s",cate);
printf("How many brands do u want to add?");
scanf("%d",&bra);
for(;;)
{
printf("Enter brand name");
scanf("%s",iname);
printf("Enter Buying price(bulk)");
scanf("%lf",&amut_b);
puts("Enter Quantity in bulk");
scanf("%d",&qty_bulk);
puts("Enter Quantity of items (number of items in a box)");
scanf("%d",&qty_u);
T_qty_u=qty_bulk*qty_u;
T_amut_blk=amut_b/qty_u;
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') /* look for any sign of no */
break;
}
getchar();
}
with the while loop this is the code
#include <stdlib.h>

case '5':
exit(1);
break;
}
return 0;
getchar();
}
