You should be using endl, not end1 (as in lowercase L, not one).

thx for helping -just joined....

ZZZZ

Code:

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <iostream>
int func(void);
void func2(void);

int func(void)
{
    int total1,seconds,minutes;
   do{
        try
        {
            system ("cls");
            printf("\nTask 4: Time count\n");
            printf("==================\n");
            printf("Please enter how many minutes to count down <5 minutes or less>:");
            scanf("%d",&minutes);
            if(minutes>=0&&minutes<6)
              {
                    printf("\n%02d:00\n",minutes);
                    _sleep(100);
                    minutes--;
                    for(;minutes>=0;minutes--) 
                    {  
                       for(seconds=59;seconds>=0;seconds--)
                      {  
                       printf("%02d:%02d\n",minutes,seconds);
                       _sleep(100);
                      }
                     }
                     _sleep(100);
              }
              else
           {
            system ("cls");
            throw "out of range";
            } 
            
            }
        
        catch (const char *e)
        {
         
         std ::cerr <<e<<std::endl;;   
        } 
        _sleep(100);
    }while(minutes>=6||-1>minutes); 
}

int main()
{
    func();
    return (0);
    
}

It is silly to throw and catch an exception here. You should just perform that range check and act accordingly.

Furthermore, you should make your indentation more consistent. Unless you have special reasons to do otherwise, you should also use C++ style I/O rather than C style I/O. If you really did need to throw an exception, #include <stdexcept> and thow std::out_of_range rather than a string literal.
