Lỗi segmentation fault (core dumped)

[thuthien2010]

Chương trình của mình sau khi biên dich thì không có lỗi nhưng khi chạy thử thì máy báo lỗi segmentation fault (core dumped).Đó là lỗi j ? Mình phải sửa sao? Ai biết chỉ jum mình nhé! cảm ơn nhìu.

post cái source ra đây mới phân tích được sai ở đâu mà sinh ra cái segment fault

Sửa lại hàm sau đây xem nào:

int kttoantu(char a)
{   
    if((a=='+')||(a=='-')||(a=='*')||(a=='/'))  //Edited by Dreaminess
        return (TRUE);
    else
        return (FALSE);
}

[thuthien2010]

thanks Dreaminess nhìu nha! Mình sửa được rồi.Nhưng mình ko hỉu sao chỗ đó lại bị lỗi zậy?
