C pass int array pointer as parameter into a function

Question

I want to pass the B int array pointer into func function and be able to change it from there and then view the changes in main function

#include 

        

Answer 1

Using the really excellent example from Greggo, I got this to work as a bubble sort with passing an array as a pointer and doing a simple -1 manipulation.

#include

void sub_one(int (*arr)[7])
{
     int i; 
     for(i=0;i<7;i++)
    {
        (*arr)[i] -= 1 ; // subtract 1 from each point
        printf("%i\n", (*arr)[i]);

    }

}   

int main()
{
    int a[]= { 180, 185, 190, 175, 200, 180, 181};
    int pos, j, i;
    int n=7;
    int temp;
    for (pos =0; pos < 7; pos ++){
        printf("\nPosition=%i Value=%i", pos, a[pos]);
    }
    for(i=1;i<=n-1;i++){
        temp=a[i];
        j=i-1;
        while((temp=0)) // while selected # less than a[j] and not j isn't 0
        {
            a[j+1]=a[j];    //moves element forward
            j=j-1;
        }
         a[j+1]=temp;    //insert element in proper place
    }

    printf("\nSorted list is as follows:\n");
    for(i=0;i

I need to read up on how to encapsulate pointers because that threw me off.
