Thread: Passing Argument-Incompatale Pointer Error

Hi, i'm trying to run a method i have, but once i compile it gives me the error:

"warning: passing argument 3 of âfindGradeâ from incompatible pointer type"

I have the right parameters for the method though.

Code:

int main(Void)
{
int answer[100][29];
int grade[100];
int miss[100][29];
int count;
int two;

count = getInput(answer);
findGrade(answer, count, grade, miss); <-GIVING ME THE ERROR HERE

}

int getInput(int answer[][TOTAL_QUESTIONS])
{
char c;
int i;
int j;
int lines=0;

   while(scanf("%c", &c) != EOF)
    {
     if(c != '\n')
      {  
       if (lines <= 75 && j != 29)
        {
         answer[i][j] = atoi(&c); 
          j++;
        }
        else if (j < 29)
         lines++;
      }
      
      else
      i++;
      j=0;
      return lines; 
      //lines=0;   
     }

   // for (i=0;scanf("%c", &c);i++)
  //  {
  //   for (j=0; j <= 29; j++)
  //    {
  //   answer[i][j] = atoi(&c); 
  //    }
  //  if(c == '\n')
 //   lines++;
 //   }
   

    

    

}

void findGrade(int answer[][TOTAL_QUESTIONS], int count, double grade[], int miss[][TOTAL_QUESTIONS]) THE METHOD ITSELF
{
int i;
int j;
   for (i=0; i<=100; i++)
   {
     for (j=0; j<=29; j++)
     {
      if (answer[i][j] != miss[i][j])
       printf("%d",j);
     }
   } 
    count++;
    miss[i][j] = count;
    printf("%d",count);
}

Help would be appreciated.

oh wait, i figured out the problem. When i made a new local grade array...i made it as an int instead of a double.

Aright, i am now at a 3rd method.
Its where i now retrieve certain parts of a text file, the method is called "outputresult"
It's goal is to retrieve each of the grades from a text file i got.
So far, i computed the grade in teh findGrade method and want to retrieve it for outputresult.

Here's more of my source code, with findGrade but now finished:

Code:

void findGrade(int answer[][TOTAL_QUESTIONS], int count, double grade[], int miss[][TOTAL_QUESTIONS])
{
int i;
int j;
count=0;
double total=0.00;
   for (i=0; i<=count; i++)
   {
     for (j=0; j<=TOTAL_QUESTIONS; j++)
     {
      if (answer[i][j] == answer[0][j])
      {
       miss[i][j] = 1;
       total = total + 1;
      }
      else
       miss[i][j] = 0;
     }
     grade[i] = (double)total/TOTAL_QUESTIONS * 100;
     
     total = 0; 
   }
    
}

double findAvg(double grade[],int count)
{
int i=0;
int j=0;
double total = 0.00;
count = MAX_STUDENTS;

for(i=1;i < count;i++)
 {           
  total = total + grade[i];
 }

return (double)total/(count-1);


}

void printHeading(void)
{
printf("Student \t Grade Answer\tWrong Questions\n");
//printf("Question\tKey\tCorrect perc. Students\tNumber of Responses\n");
//printf("After Sort:\n");
//printf("Grade\tFrequency:\n");
}

void outputResult(int answer[][TOTAL_QUESTIONS], int count, double grade[], int miss[][TOTAL_QUESTIONS])
{
int i = 0;
int j = 0;
char c;


  // printf("before loop");
    for(i=1;i<TOTAL_QUESTIONS;i++)
     {
      findGrade(answer, count, grade, miss);
      printf("%f\n", grade[i]);
     }
    
  //  printf("%f",grade);
 


}

When i run it...it just gives me:

0.00
0.00
0.00
0.00
0.00
0.00
0.00
0.00
0.00

instead of for example:

38.24
33.11
76.55
44.33
22.89
102.45
etc.

Help would be appreciated!
