在C中，将结构传递给单独函数时出现问题

我无法将结构传递给新函数。我的当前代码打开一个文本文件，将相关信息保存到结构中，并打印保存的信息。现在我尝试编写一个函数，要求用户输入一个名称，让代码检查结构中的所有名称字段，并在找到结果后返回信息。在我尝试将结构传递给“SearchName”函数之前，代码工作正常。main显示我已经正确地保存了相关信息，我对“searchDroneName”函数也做了同样的操作。但是，当我在“searchDroneName”函数中打印出结构的保存信息时，它会打印出一堆随机数和奇怪的字符

我相信这只是因为我对功能和如何传递信息缺乏了解，但非常感谢您的帮助，谢谢

代码如下：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define DRONE_COUNT 10

typedef struct{

    int drone_number;
    char drone_name[20];
    int year_manufactured;
    double mass;
    double top_speed;
    double max_distance;
    double load_capacity;

} drone_info;


int searchDroneName(int no_of_drones){
    drone_info droneinfo[10];

    int i, found, numdrones;
    char namechoice[20];
    numdrones = no_of_drones;

    // Test Data    
        printf("Data:\n\n");
    for (i=0; i < numdrones; i++){
        printf("ID: %d Name: %s  Year: %d  Mass: %.2f  Top Speed: %.2f  Max Distance: %.2f Load Capacity: %.2f\n", 
        droneinfo[i].drone_number, droneinfo[i].drone_name, droneinfo[i].year_manufactured, droneinfo[i].mass, droneinfo[i].top_speed, droneinfo[i].max_distance, droneinfo[i].load_capacity);

    }


    printf("Input Drone Name: ");
    scanf("%19s", namechoice);
    found = 0;
    for (i=0; i < numdrones; ++i){
        printf("Drone Name: %s\n", droneinfo[i].drone_name);

        if (!strcmp(namechoice, droneinfo[i].drone_name)){

        printf("FOUND A MATCH");
        found = 1;
        }

    }

    if(found == 0){
        printf("No Matches Were Found!\n");

    }

    return 0;
}






int main(void) {
drone_info droneinfo[10];

        droneinfo[i].drone_number = droneID;
        strcpy(droneinfo[i].drone_name, dronename);
        droneinfo[i].year_manufactured = yrman;

        droneinfo[i].top_speed = dronetopspd;
        droneinfo[i].max_distance = dronemaxdist;
        droneinfo[i].load_capacity = droneload;

您需要阅读更多关于变量、变量生存期和变量范围的内容。您有两个完全不相关的

droneinfo

变量。要将

droneinfo

从

main

函数传递到

searchDroneName

函数，您需要将其作为参数传递。非常感谢。My对函数和传递值的理解真的很糟糕。欣赏它：D

    case 2:
    //Search Drone function
    searchDroneName(no_of_drones);

    case 2:
    //Search Drone function
    searchDroneName(droneinfo, no_of_drones);
