C++ 函数模板实例二

• 利用函数模板封装一个排序的函数，可以对不同数据类型数组进行排序

• 排序规则从大到小

• 分别利用char数组和int数组进行测试

using namespace std;

template
void printMsg(vector &nums,int len)
{
    for(int i = 0;i
void mySwap(T &a,T &b)
{
    T temp = a;
    a = b;
    b = temp;
}
template
void mySort(vector &nums,int len)
{
    for(int i = 0;inums[j+1]){
                mySwap(nums[j+1],nums[j]);
            }
        }
    }
   
}

void test01()
{
    vector nums{1,4,2,1,5,3};
    int len = nums.size();
    mySort(nums,len);
    printMsg(nums,len);
}
void test02()
{
    vector nums{1.2,3.6,5,8.9,5.22};
    int len = nums.size();
    mySort(nums,len);
    printMsg(nums,len);
}
void test03()
{
    vector nums{"efgh","ijkl","abcd"};
    int len = nums.size();
    mySort(nums,len);
    printMsg(nums,len);
}
void test04()
{
    vector nums{'e','d','c','f','a'};
    int len = nums.size();
    mySort(nums,len);
    printMsg(nums,len);
}
int main()
{
    test01();
    test02();
    test03();
    test04();
    return 0;
