Reverse the order of a n-element array in C
What am I doing incorrectly and how can I fix?
My code:
#include <stdio.h>
sort(int *p, int m)
{
//Write your code here
for(int i = 0; i<n/2; i++){ temp = arr[i]; arr[i] = arr[n-i-1]; arr[n-i-1] = temp; }
}
main(){
int i, n;
int *p, num[20];
printf("input n:");
scanf("%d", &n);
printf("please input these numbers:\n");
for (i = 0; i < n; i++)
scanf("%d", &num[i]);
p = &num[0];
sort(p, n);
printf("Now, the sequence is:\n");
for (i = 0; i < n; i++)
printf("%d ", num[i]);
}
