可以通過兩種方法將數組逆序存放:
#include <stdio.h>
void reverseArray(int arr[], int size) {
int temp;
for (int i = 0; i < size / 2; i++) {
temp = arr[i];
arr[i] = arr[size - i - 1];
arr[size - i - 1] = temp;
}
}
int main() {
int arr[] = {1, 2, 3, 4, 5};
int size = sizeof(arr) / sizeof(arr[0]);
reverseArray(arr, size);
printf("Reversed Array: ");
for (int i = 0; i < size; i++) {
printf("%d ", arr[i]);
}
return 0;
}
#include <stdio.h>
void reverseArray(int *arr, int size) {
int temp;
int *start = arr;
int *end = arr + size - 1;
while (start < end) {
temp = *start;
*start = *end;
*end = temp;
start++;
end--;
}
}
int main() {
int arr[] = {1, 2, 3, 4, 5};
int size = sizeof(arr) / sizeof(arr[0]);
reverseArray(arr, size);
printf("Reversed Array: ");
for (int i = 0; i < size; i++) {
printf("%d ", arr[i]);
}
return 0;
}
