    Basic function functioning

    Hi

    This should work, only its dosent. would anyone be kind enough to gently point me in the right direction? It tells me that array is undeclared in "void judge" if thats worth anything. heres the code

    Code:
    #include <stdio.h>
    #include <conio.h>
    
    
    void judge(int Array[]);
    void count(int Array[], int *total);
    
    main()
    {
    int sum;
    int array[5]={0};
    printf("Points are being counted\n\n");
    
    judge(array);
    count(array, &sum);
    
    printf("%d", sum);
    getch();
    }
    
    void judge(int Array[])
    {
    int i;
    for(i=1; i<5; i++){
             printf("Give %d. judges points\n", i+1);
             scanf("%d", &array[i]);
             }
    
    }
    
    void count(int Array[], int *total)
    {
          for(i=1; i<5; i++){
          &sum+=array[i];
          }
    }

    First of all, using a hard-coded value to keep track of the array size is error-prone and generally considered bad form. You should pass it as a parameter to the function. As to the error, it's because the variables 'array' and 'sum' are not visible (nor do they exist) within the context of the function. You could of course make them global variables (eg: outside of main) but this also is usually an indication of a bad design. At any rate, you probably meant to use the variables that you passed to the function 'Array' and 'total', correct? Even so, attempting to add the elements of the array to the address of 'sum' doesn't make much sense, either, does it?

    also your sum variable is not initialized, so it contains garbage. Suppose you'll fix the part that adds the elements of the array to the correct total, what it will be if you start with some random value?
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.
