Question

I have this very simple code:

#include <stdio.h>
#include <stdlib.h>


int maxArr(int *arr)
{
    int i=0;
    for (i = 0; i < 10; ++i)
    {
        printf("%d\n",arr[i]);
    }
    return 0;
}


int main()
{
    int* i = {0,1,2,3,4,5,6,7,8,9};
    maxArr(&i);
    return 0;
}

but instead of printing 0,1,2,3,4,…,9

I’m getting this:

0
0
0
0
0
0
1809693728
32767
203279940
1

Why?

Answer 1

You need to pass in i, not &i

int main()
{
    int* i = {0,1,2,3,4,5,6,7,8,9};
    maxArr(i);
    return 0;
}

Instead of iterating through the array, you are iterating through memory addresses starting at &i.
