title: Redeclared as different kind of symbol in c program
body: <p>I'm currently working on a program for school. I need to create a chart of temperature conversions given by the user of between 1 to 100. I keep getting the error "redeclared as different kind of symbol" and I'm not sure how to fix it. I also included a picture of the compiler with the errors. <a href="http://i.stack.imgur.com/8tXOV.png" rel="nofollow">compiler image</a></p>
  
  <pre><code>#include &lt;stdio.h&gt;
  
  int toFahrenheit(int celOne, int fahOne);
  
  int toCelsius(int celTwo, int fahTwo); 
  
  
  int main(void) {    //main
  
  
      int tempNum;   //intialize user given temperature
      int tempNumnegative = -tempNum; //initialize negative temperature num
  
  
      //ask user for number between 1 and 100
      printf ( "\nPlease enter an odd number between 1 to 100:" );
      scanf ("%d", &amp;tempNum);
  
      //If Else statement to make sure it is a number between 1 to 100 and reject other numbers
  
      if ( (tempNum &gt; 100) || (tempNum &lt; 1) ) {
          puts ( "\nError; Number must be a number between 1 to 100." );
          }
  
      else { 
  
      printf("\n____________________________");
      printf(" C\tF\t|\t|\tF\tC");
      printf("\n____________________________");
  
      //For loop to print 
      for ( tempNumnegative &gt;= tempNum; tempNumnegative++ ) {
          printf("\n%d\t%d\t|\t|\t%d\t%d\n", toFahrenheit(int celOne, int fahOne) , toCelsius(int celTwo, int fahTwo));
      } 
      }
  }
  
  int toFahrenheit(int celOne, int fahOne) //function
  {  
  
      int celOne= tempNum; //celcuis one equals the given value
      int fahOne = (9 / 5) * celOne + 32; //equation for f to c
  }
  
  int toCelsius(int celTwo, int fahTwo) //function
  {
  
      int fahTwo = tempNum; 
      int celTwo = (5 / 9) * (fahTwo - 32); //equation for c to f 
  }
