是否可以在结构中存储多个值？

Question

我是 c 的新手，我想知道是否可以在结构中存储许多值？ .我想存储 x1、y1、x2、y2 的 1 个以上的值。然后我想要一个随机值 x1,y1,x2,y2。使用结构是否可行，或者我需要使用其他工具？

struct test
{
    int x1;
    int y1;
    int x2;
    int y2;
};

看来你需要一个数组。

#include <time.h> //you need this to use time(NULL)
#include <stdlib.h> //you need this for random numbers functions
#include <stdio.h> //you need this for printf

//this is called a macro, it will get replaced by value 10 everywhere in the following code
#define NUM_OF_VALUES 10

struct test
{
    int x1[NUM_OF_VALUES];
    int y1[NUM_OF_VALUES];
    int x2[NUM_OF_VALUES];
    int y2[NUM_OF_VALUES];
}

int main() {

    struct test my_test = { /* learn about initializes */ };

    srand(time(NULL)); //this is how you initialize random number generator to be different every time you run your code

    printf("Random value from x1 %d\n", my_test.x1[rand() % NUM_OF_VALUES]);
    printf("Random value from y1 %d\n", my_test.y1[rand() % NUM_OF_VALUES]);

    return 0;
}
