problem is with the following lines
if(opt==1)
{
cout<<"\nRoom\tStatus\n";
for(int i=1; i<=10; i++ )
{
if(room.roomId[1][i]>0)
{
cout<<room.roomId[1][i]<<"\t Occupied\n";
}
}
}
else if(opt==2)
{
cout<<"\nRoom\tStatus\n";
for(int i=1; i<=10; i++ )
{
if(room.roomId[2][i]>0)
{
cout<<room.roomId[2][i]<<"\t Occupied\n";
}
}
}
else if(opt==3)
{
cout<<"\nRoom\tStatus\n";
for(int i=1; i<=10; i++ )
{
if(room.roomId[3][i]>0)
{
cout<<room.roomId[3][i]<<"\t Occupied\n";
}
}
}
room.roomId[1][i] is empty but room.roomId[2][i] and room.roomId[3][i] brings some garbage value. i could share my whole source code if u need.
this array is supposed to take values from another variable but how can it takes values without assigning it to him.
