C++ 函数重载实现数组排序

C++ 函数重载实现数组排序

C++ 函数重载实现数组排序

代码如下：

#include 

using namespace std;
//使用重载实现数组的排序
//重载：函数名相同，参数列表（特征标不同）

//实现排序
void Sort(int[], int len);
void Sort(float[], int len);
void Sort(double[], int len);

//实现输出
void Show(int[], int len);
void Show(float[], int len);
void Show(double[], int len);



void Sort(int nums[], int len){
	int temp;
	for (int i = 0; i < len - 1; i++) {
		for (int j = 0; j < len - i - 1; j++) {
			if (nums[j] < nums[j + 1]) {
				temp = nums[j];
				nums[j] = nums[j + 1];
				nums[j + 1] = temp;
			}
		}
	}
}

void Sort(float nums[], int len) {
	float temp;
	for (int i = 0; i < len - 1; i++) {
		for (int j = 0; j < len - i - 1; j++) {
			if (nums[j] < nums[j + 1]) {
				temp = nums[j];
				nums[j] = nums[j + 1];
				nums[j + 1] = temp;
			}
		}
	}
}

void Sort(double nums[], int len) {
	double temp;
	for (int i = 0; i < len - 1; i++) {
		for (int j = 0; j < len - i - 1; j++) {
			if (nums[j] < nums[j + 1]) {
				temp = nums[j];
				nums[j] = nums[j + 1];
				nums[j + 1] = temp;
			}
		}
	}
}

void Show(int nums[], int len) {
	for (int i = 0; i < len - 1; i++) {
		cout << nums[i] << ", ";
	}
	cout << endl;
}

void Show(float nums[], int len) {
	for (int i = 0; i < len - 1; i++) {
		cout << nums[i] << ", ";
	}
	cout << endl;
}

void Show(double nums[], int len) {
	for (int i = 0; i < len - 1; i++) {
		cout << nums[i] << ", ";
	}
	cout << endl;
}

int main(){

	int iNums[] = { 56 ,47, 13, 89, 32 };
	float fNums[] = { 10.8f, 28.6f, 35.5f, 50.2f, 99.9f };
	double dNums[] = { 70.8, 65.9, 22.2, 84.3, 53.4 };

	cout << "排序前：" ;
	Show(iNums, sizeof(iNums) / sizeof(iNums[0]));
	Sort(iNums, sizeof(iNums) / sizeof(iNums[0]));
	//Sort(iNums, sizeof(iNums) / sizeof(int));
	cout << "排序后：" ;
	Show(iNums, sizeof(iNums) / sizeof(iNums[0]));

	cout << endl;

	cout << "排序前：";
	Show(fNums, sizeof(fNums) / sizeof(fNums[0]));
	Sort(fNums, sizeof(fNums) / sizeof(fNums[0]));
	//Sort(fNums, sizeof(fNums) / sizeof(int));
	cout << "排序后：";
	Show(fNums, sizeof(fNums) / sizeof(fNums[0]));

	cout << endl;

	cout << "排序前：";
	Show(dNums, sizeof(dNums) / sizeof(dNums[0]));
	Sort(iNums, sizeof(dNums) / sizeof(dNums[0]));
	//Sort(iNums, sizeof(dNums) / sizeof(int));
	cout << "排序后：";
	Show(dNums, sizeof(dNums) / sizeof(dNums[0]));
}
