title: Calling functions multiple times with different values within the same function
body: <p>Ive tried just making a lot of lines of different variables for entering courses, then the courses being assigned to credits and output on a receipt. But instead of having the 300+ lines of switches I wanted to make a switch function that I could call. I figured I would make a for loop to run the switch function based on the amount of courses the person chose, but when I run it the code seems to just run forever without even hitting a return 0 to end the program. Any tips for calling the function or if im doing it poorly?</p>
  
  <pre><code>int studentId, var, i;
  float first;
  int course, course1, course2;
  float second, amount;
  float credit1, credit2, credit3, credit4, credit5, credit6, credit7, credit8;
  float paymentA, paymentB, paymentC, paymentD, total;
  float creditA, creditB;
  char *a;
  
  
  void courseInfo(int myCourse){
      switch(myCourse)
      {
               case 4587:
                  credit1 = 4;
                  a = "MAT 236";
                  break;
              case 4599:
                  credit1 = 3;
                  a = "COP 220";
                  break;

  <p>I just wanted the input to say 3 courses for example, you would input the 3 courses CRNs you wanted to take, it would run into the function and then print out the prices and what you were taking, then repeat the loop for the next 3. I figured if nothing was input like if someone chose 1 course, the course1 and course2 variables would not be assigned a value thus skipping the switch</p>
