Day of Week Program

[pbri4141]

I cant get my program to run, but it compiles without any problems. Can anyone help me out with this.

Thanks





#include <iostream>

{
int month, day, year;
int u,v,m,y,w,dayofweek;
bool leap;
string monthname;
string dayname;

cout<< "Enter numeric values for month, day and year of a date>" <<endl;
cin>>month>>day>>year;

if (month == 01)
monthname = "January ";
else if (month == 02)

What error Message do you get?
What do you mean by you can't get it to run?

It works fine here, so maybe you just wonder why the window closes so fast ^^
write system("pause") at the end of the programm, then the window will stay open ;)
