Question

分别编写三个同名的函数max,在整数数组,double数组,字符数组中取得其中的最大值并输出，在主函数中调用这三个函数

Answer 1

#include <iostream>
using namespace std;

double max(double* data, int count)
{
    if (count <= 0){
        return DBL_MIN;//错误代码
    }
    double maxValue = data[0];
    for (int i = 1; i < count; ++i) {
        if (maxValue < data[i]){
            maxValue = data[i];
        }
    }
    return maxValue;
}

char max(char* data, int count)
{
    if (count <= 0) {
        return CHAR_MIN;//错误代码
    }
    char maxValue = data[0];
    for (int i = 1; i < count; ++i) {
        if (maxValue < data[i]) {
            maxValue = data[i];
        }
    }
    return maxValue;
}

int max(int* data, int count)
{
    if (count <= 0) {
        return INT_MIN;//错误代码
    }
    int maxValue = data[0];
    for (int i = 1; i < count; ++i) {
        if (maxValue < data[i]) {
            maxValue = data[i];
        }
    }
    return maxValue;
}

int main()
{
    int intArray[] = {0, 1,2,3,4,5,6};
    double doubleArray[] = {0, 1,2,3,4,5,6};
    char charArray[] = { 0, 1, 2, 3, 4, 5 };

    std::cout << "int max = " << max(intArray, sizeof(intArray) / sizeof(int)) << endl;
    std::cout << "double max = " << max(doubleArray, sizeof(doubleArray) / sizeof(double)) << endl;
    std::cout << "char max = " << (int)max(charArray, sizeof(charArray) / sizeof(char));//因为存在不可见的字符，为了不打印出乱码，强制装换为int
    
    int i;
    cin >> i;
    return 0;
}
