程序检查油箱是否在给定时间内溢出，下溢或充满

给定具有确定的高度和半径的水箱，以及可用于填充水箱的水流。确定储罐在给定的时间内是否会溢出。
注意：水流量将以每分钟的体积为单位。
例子：

--r=5--
   ----------   ^
   |         |  |
   |         |  |
   |         |  h = 10
   |         |  |
   ----------   ^
        
   rate_of_flow = 10

Input : given_time = 10.0
Output : Underflow

Input : given_time = 100.0
Output : Overflow

方法：
圆柱罐的体积为(22/7)*半径*半径*高度。首先，找出完全充满水箱所需的时间，然后将其与给定时间进行比较。如果给定时间大于所需时间，则将导致溢出状态。如果给定的时间少于所需的时间，则将导致下溢情况，否则油箱将被注满。
下面是上述方法的实现：

// C++ program to check if Tank will
// overflow or not in given time
#include

// function to calculate the volume of tank
float volume(int radius, int height)
{
    return ((22 / 7) * radius * radius * height);
}
 
// function to print overflow / filled /
// underflow accordingly
void check_and_print(float required_time,
                       float given_time)
{
    if (required_time < given_time)
        cout << "Overflow";
    else if (required_time > given_time)
        cout << "Underflow";
    else
        cout << "Filled";
}
