一个完整的用C++编写的程序，它会接受一个浮点数（double 类型）的输入，并找出该浮点数中整数部分和小数部分的最大及最小数字。完整的程序

当然可以。下面是一个简单的C++程序，用于接收用户输入的浮点数，将其拆分为整数部分和小数部分，然后分别找到最大和最小的数字：

#include <iostream>
#include <cmath>

// Function to extract integer and decimal parts of a float
void splitAndFindMinMax(double number) {
    int intPart = static_cast<int>(number); // Integer part (truncating)
    double fracPart = std::modf(number, &intPart); // Decimal part (remaining fraction)

    // Finding max and min of the integer part
    int minInt = intPart;
    int maxInt = intPart;

    // If there is a fractional part, find its minimum and maximum
    if (fracPart != 0.0) {
        minInt = std::min(minInt, static_cast<int>(fracPart));
        maxInt = std::max(maxInt, static_cast<int>(fracPart));
    }

    std::cout << "Integer Part Min: " << minInt << "\n";
    std::cout << "Integer Part Max: " << maxInt << "\n";

    // Since the decimal part is always between 0 and 1, we can directly print it as is
    std::cout << "Decimal Part: " << fracPart << "\n";
}

int main() {
    double inputNumber;
    std::cout << "Enter a floating point number: ";
    std::cin >> inputNumber;

    // Call the function with user input
    splitAndFindMinMax(inputNumber);

    return 0;
}

当你运行这个程序并输入一个浮点数时，它将分别显示整数部分的最小值、最大值以及小数部分。
