Well, your code as posted is not readable. So, you can start by re-posting your code within [code] ...code blocks... [/code] to make it readable.

The error means that you are most likely missing a '}' somewhere after that point.

I tried my best to locate it,but i cant.Can you locate it?

46. cin>>temp;
47. {
48. if( temp<1&&temp>100 )
49. {cout<<"ERROR! you have not entered an integer.Please enter an integer! "<< endl;}
50. }//this if ends

Are you sure you have your braces correctly paired here? The brace on Line 50 closes the block opened on Line 47, not your if statement; the if ends on Line 49. Have another look (reformatted for readability):

cin >> temp;
{
  if (temp < 1 && temp > 100) {
    cout << "ERROR! you have not entered an integer.Please enter an integer! "<< endl;
  }
}//this if ends

There are several such examples throughout that function's implementation... I would also suggest you do better about your indentation. The top part of your code isn't too bad, but the bottom is awful. It almost looks like it was written by 2 different people...

Using braces is a good idea, but I think you need to position them better:

52. for(int i=0;i<count;i++)
53. {if(temp==roll_no[i])
54.  {if(dues[i]==1)
55.    {cout<<"BOOKS ARE ALREADY ISSUED ON THIS ROLL NUMBER, SORRY"<<endl; return;}
56.  }//nested if ends
57. }//pre if ends

there are 2 common schools of though on placement, I prefer this way:

for (int i = 0; i < count; ++i) {
  if (temp == roll_no[i]) {
    if(dues[i] == 1) {
      cout << "BOOKS ARE ALREADY ISSUED ON THIS ROLL NUMBER, SORRY" << endl;   return;
    } //end dues if
  } //end temp if
} //end for

but others prefer this way instead:

for (int i = 0; i < count; ++i)
{
  if (temp == roll_no[i])
  {
    if(dues[i] == 1)
    {
      cout << "BOOKS ARE ALREADY ISSUED ON THIS ROLL NUMBER, SORRY" << endl;   return;
    } //end dues if
  } //end temp if
} //end for

Notice how much easier they make it to see them?

Well look, there is a '{' that opens before if and then it gets closed too.
Similarly, there is a '{' that opens for cout and then it gets closed after endl.How is it wrong?

The opening brace on line 67 isn't properly closed before the next case. This is what happens when you have a piss poor bracing style. :icon_rolleyes:

Yeah right. Sorry for bothering you =)
