Answer 1

you declared display function that accepts two integers:

void display(int arr, int size)

but you're passing an interger array and an integer:

display(arr, size);

so it complains about it.
you can either declare the display function as:
void display(int arr[], int size)
or
void display(int *arr, int size)

also:
function main lacking it's pharanteses ().

with an array the last index is array size - 1 because indexes start from 0 (in this case 4, that is 0 to 4 which are 5 elements) so you need to discard the '=' and use '<' comparison operator.
all together:

void display(int arr[], int size){
for(int i = 0; i < size; i++){
printf("%d ", arr[i]);
}
}

int main(int argc, char *argv[]){
int arr[] = {1, 3, 5, 7, 9};
int size = sizeof(arr)/sizeof(arr[0]);
display(arr, size);
return 0;
}

what I added to main as arguments are not mandatory yet it's strongly advised.
