闲杂篇（一）vs2017 c语言、c++从一个函数返回多个参数给主函数|c++函数之间结构体如何传递参数

main.cpp

#include 
using namespace std;

int main() {
	cout << "*********************************************************************" << endl;
	cout << "vs2017 从一个函数返回多个参数给主函数|函数之间结构体如何传递参数" << endl;
	cout << endl << endl;
	
	listptr a = NULL;
	a = (listptr)malloc(sizeof(list));
	*a = (re)malloc(sizeof(Result));
	a= first(1, 2);
	printf("第一种方法：------------------------------n");
	cout << *((*a)->s_arr) << endl;
	printf("position:%d ns_arr:%d,%d,%d", (*a)->position,(*a)->s_arr[0], (*a)->s_arr[1], (*a)->s_arr[2]);


	cout << endl << endl;
	
	PARAMSAVE   set;
	set = second(1, 2);
	printf("n第二种方法：------------------------------n");
	printf("position:-------------------------n");
	for (int i = 0; i < 3; i++)

			printf("%f ", set.position[i][j]);
		cout << endl;
	}
		
	printf("s_arr:-------------------------n");
	for (int i = 0; i < 10; i++)
		printf("%f :", set.s_arr[i]);
	system("pause");

第二个文件

jiegouti.h

#pragma once
#ifndef JIEGOUTI_H
#define JIEGOUTI_H


typedef struct
{
	int position[2][3];;
	int s_arr[3];
}Result,*re;
typedef re list, *listptr;
extern listptr first(int x, int y);



typedef struct ParamSave {
	double position[3][10 + 1];
	double s_arr[10];
}PARAMSAVE;
extern PARAMSAVE second(int startPoint, int middlePoint);

#endif JIEGOUTI_H 

头文件

jiegouti.cpp

#include 
using namespace std;
#include "jiegouti.h"

listptr first(int x, int y) {
	listptr ret = NULL;
	ret = (listptr)malloc(sizeof(list));
	*ret = (re)malloc(sizeof(Result));

	for (int i = 0; i < 2; i++)
	{
		for (int j = 0; j < 3; j++)
		{
			(*ret)->position[i][j] = x + y;
		}
	}
	(*ret)->position[0][0] = x+y;
	(*ret)->s_arr[0] = 1;
	(*ret)->s_arr[1] = 1;
	(*ret)->s_arr[2] = 1;
	return ret;

}

PARAMSAVE   haha;
PARAMSAVE second(int x, int y) {

	for (int i = 0; i < 3; i++)
		for (int j = 0; j < 10; j++)

			haha.position[i][j] = x + y;
	for (int i = 0; i < 10; i++)
		haha.s_arr[i] = 1;
	return haha;
}

1.在公众号后台领取，里面有我分享的学习资源，文件命名：vs2017结构体传参
2.或者去找我上传到压缩包《vs2017 c语言、c++从一个函数返回多个参数给主函数|c++函数之间结构体如何传递参数》
