main.c

#include <stdio.h>
#include "BaseStore.h"

int main()
{
   	baseStore_aboutSizeofFunc();
    return 0;
}

BaseStore.h

#include <stdio.h>

void baseStore_aboutSizeofFunc();

BaseStore.c

#include "BaseStore.h"

void baseStore_aboutSizeofFunc()
{
    int integerType;
    float
 
 floatType;
    double doubleType;
    char charType;

    // sizeof操作符用於計算變數的位元組大小
    printf("size of int: %d bytes\n",sizeof(integerType));
    printf("size of float: %d bytes\n",sizeof(floatType));
    printf("size of double: %d bytes\n",sizeof(doubleType));
    printf("size of char: %d bytes\n",sizeof
 
(charType));
    return;
}

重點在於編譯: 在tasks.json 檔案中包含要引用的檔案

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build hello world",
            "type": "shell",
            "command"
 
: "gcc",
            "args": [
                "-g","main.c",
                "-g","BaseStore.c"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

編譯執行

E:\C_Study>gcc main.c BaseStore.c -o main

E:\C_Study>main.exe
size of int: 4 bytes
size of float: 4 bytes
size of double: 8 bytes
size of char: 1 bytes

E:\C_Study>

問題:

main.c引入多個C檔案該怎麼辦？求大神指導
