something worng with my program need help please,,

[idris]

hi,, the program i made is soppost to reads 3 integers from user and solve the average, the maximum, the minimum and their median value..the problem with the program is that the median section is not working, can u please have a look at it..

#include<stdio.h>

main( ) 
{  

  int item[100];
  float a, b, c;		 
  int median_index; 
  float median;
  int count;
  float sum;
   			 

 printf("Enter your first integer\n"); 
 scanf(" %f", &  a); 
 
printf("Enter your second integer\n");
scanf(" %f", & b);

printf("Enter your third integer\n");
scanf(" %f", &  c);

        
    sum = (a + b + c)/3;        
    
      for(a=0; a<count; a++){
       scanf("%f", &item[a]);
}
 
       for(a=1; a<count; a++)
       for(b=count-1; b>=a; --b){
             if(item[b-1] > item[b]){
                c=item[b-1];
                item[b-1] = item[b];
                item[b]=c;
      }
    }
  median = count/2;
  if(count%2 ==1){
  printf("There are odd sets of numbers.\n");
  median = item[count/2];

    }
  else{
  median_index = count/2;
  printf("There are even sets of numbers.\n");
   median = (item[median_index]+item[median_index-1])/2.0;
  }
 
 
  for(c=0; c<count; c++){
    printf("%f\n", item[c]);

  }
								
   printf("\nThe average is %0.2f\n", sum);
   printf("The median is %0.2f\n", median);									 								
    if ((a > b) && (a > c)) 
    printf("The maximum %0.2f\n", a); 	

       else if ((b> a) && (b> c))
        printf("The maximum is %0.2f\n", b);
               			
        else printf("The maximum is %0.2f\n", c);


    if ((a < b) && (a < c))            			                     printf("The minimum is %0.2f", a);				           

else if ((b < a) && (b < c))
printf("The minimum is %0.2f", b);
               				
else printf("The minimum is %0.2f", c);
               				
               	
 return 0; 


       }

But now, I can't run the program because there are some errors, all saying:

1.C:42: invalid types `int[100][float]' for array subscript
1.C:46: invalid types `int[100][float]' for array subscript
1.C:47: invalid types `int[100][float]' for array subscript
1.C:48: invalid types `int[100][float]' for array subscript
1.C:49: invalid types `int[100][float]' for array subscript
1.C:66: invalid types `int[100][float]' for array subscript

What did I do wrong? Could anybody help me please?

Thank You.

You can't use floats for array subscripts.

thankz for dat,, i adjusted it..

now the porgram runs but it doesn't go through any of the loops (it only ask the user to enter the 3 integers and after that stops), why do u think dat is?

Because count is some random number?
