Thread: calendar

I need assistance with source code for a calendar Please review my input and list what is needed
#inclue<iostream.>

void start();
void firstr();
void rest();
void otpt();

int year;startc, count=1,cal [6][7];

void main()

{

cout<<"this is my calendar program."<<endl;
<<"enter any year equal to or greater then 1961:";
cin>>year;

start();
firstr();
rest();
otpt:

}

void start()

{

int diff,ly,tdiff,startc;

diff=year-1961; //(2002-1961)=41 the difference in the years that are the input
ly=int(diff/4); //ly=int(41/4)=(10.25)=10
tdiff=dif+ly; //tdiff=41 + 10=51
startc=tdiff%7; //startc=51 % 7=8 (%=mod=51/7=a remainder of 8.)
}

void firstr()

{

int y;

for (y=startc;y<7y++)
{
cal[0][y]=count
count++;

}

}

void rest()

{
int x,y;
for (x=1;x<6;x++)
for (y=0;y<7;y++)
{
cal[x][y]=count;
count++;
}

}

void otpt()

{

intx,y;
cout<<" jan "<<year<<endl;
cout<<"s"<<\tm"<<"tt:<<\tw"<<\tth"<<"\tf"<<"\ts";

for(x=0;x<6;x++);
{
for(y=0;y<7;Y++);
{
if ((cal[x][y],1)||(cal[x][y]>31))
cout<<" "<<\t";
else
cout<<cal[x][y]<<"\t";

}
}

for(x=0;x<6;x++)
{
for(y=0;y<7;y++)
cout<<cal[x][y]<<"\t";

return 0;
}
cout<<endl;
