C语言递归函数示例：递减整数

#include <stdio.h>

void recursive_func(int n) { if (n == 0) { printf('End of recursion.\n'); return; }

printf('Current value: %d\n', n);
recursive_func(n - 1);

}

int main() { recursive_func(5); return 0; }

输出：

Current value: 5
Current value: 4
Current value: 3
Current value: 2
Current value: 1
End of recursion.
