Well..Abraham..I am not checking for invalid dates in that
program.
Here is the program that u want..

#include<iostream.h>
#include<conio.h>
#include<stdio.h>

int leap(int y)
{
if(y%4==0&&y%100!=0||y%400==0)
return 1;
else
return 0;
}


int valid(int dd,int mm,int yy)
{
if(dd>31||dd<1||mm>12||mm<1||yy<0)
return 0;
if(mm<8)
if(mm%2==0&&dd>30)
return 0;
if(mm>=8)
if(mm%2!=0&&dd>30)
return 0;
if(mm==2)
{
if(yy%4==0&&dd>29)
return 0;
else
if(yy%4!=0&&dd>28)
return 0;
}
return 1;
}
main()
{
int d,m,y,i,rem;
int a[12]={31,28,31,30,31,30,31,31,30,31,30,31};
long int days=0;
clrscr();
cout<<"enter date in dd m yyyy format:";
scanf("%d %d %d",&d,&m,&y);
if(!valid(d,m,y))
{
cout<<"\nInvalid date";
getch();
return 0;
}

for(i=1;i<y;i++)
if(leap(i))
days+=366;
else
days+=365;
for(i=1;i<m;i++)
if(leap(y)&&i==2)
days+=29;
else
days+=a[i-1];
days+=d;
rem=days%7;
switch(rem)
{
case 1:cout<<"monday";
break;
case 2:cout<<"tuesday";
break;
case 3:cout<<"wedday";
break;
case 4:cout<<"thursday";
break;
case 5:cout<<"friday";
break;
case 6:cout<<"saturday";
break;
case 0:cout<<"sunday";
}
getch();
return 0;
}

In a gymnastic competition, scoring is based on the average of all scores given by the judges excluding the maximum and minimum scores. Let the user input the number of judges, after that, input the scores from the judges. Output the average score. Note: In case, more than two judges give the same score and it happens that score is the maximum or minimum then just eliminate two scores. For example, if the number of judges is 5 and all of them give 10 points each. Then the maximum and minimum score is 10. So the computation would be 10+10+10, this time. The output should be 10 because 30/3 is 10.
