Thread: Sorting student records by letter grade

I am sorting a file containging student records by grade letter, highest to lowest. I can sort it but my question is how do I make say a B+ be above a B in the order? This is my code:

insert

Code:

void sortListGrade(STUDENT records[], int count)
{
   STUDENT tempData;
   int smallest;
   int current;
   int walk;
    
     for (current = 0; current < count - 1; current++)
     {
	      smallest = current;
          for (walk = current + 1; walk <= count - 1; walk++)
		  {
	     
             if ((strcmp(records[walk].grade, records[smallest].grade)) < 0)
		         smallest = walk;
		  }
          tempData = records[current];
          records[current] = records[smallest];
          records[smallest] = tempData;
     }
	 
   return;
}

right now its printing
A
A
B
B+
B-
B-
...

I need it to print
A
A
B+
B
B-
B-
...

You could keep strcmp() if you made some other changes. Already, B+ sorts out as less than B-, so that part is done. (The B+ comes higher on the list than B-)

The only problem is the plain grades, without a plus or minus sign. Change your logic so plain grades become a letter and ASCII 44 (a comma). Now the A+'s sort out as less than A's, and the A's sort out before the A-'s.

You'll need to add the if statement, so if a grade[1], is a comma, only the letter grade will be printed, and not the comma.
