Exercise 7-3 store the numbers in the array in reverse order (20 points)

This question requires the preparation of procedures , Will be given n An integer is stored in the array , Put this... In the array n The number is stored in reverse order , Then output the elements in the array in order .

Input format :

Input gives a positive integer in the first line n（1≤n≤10）. Second line input n It's an integer , Separate with spaces .

Output format :

Output this on one line n The processing result of an integer , Adjacent numbers are separated by a space , There must be no extra space at the end of the line .

sample input :

4
10 8 1 2

sample output :

2 1 8 10

The code is as follows ：

#include<stdio.h>
int main()
{
    int n,i;
    scanf("%d",&n);
    int a[n];
    for(i=0;i<n;i++){
        scanf("%d",&a[i]);
    }
    printf("%d",a[n-1]);
    for(i=n-2;i>=0;i--){
        printf(" %d",a[i]);
    }
    return 0;
}

summary : Topics need attention , It requires that there should be no extra spaces at the end of the output line , So we should output the last element first , utilize for Loop to output other elements in turn .
