plz... help anyone
Non-standard C++ code uses 'conio.h', 'void main', 'clrscr', and 'getch' as part of how to run. This site is run based on the C++ standard so your code should be created in that manor. 'using std;' is something that makes it easier for beginners to code, but it isn't normally used in professional development. 'int main' and 'return 0' are required by the C++ standard.
