香腸炒章魚

範例碼(一)：C/C++ 語言，自訂函數及標頭檔，範例如下，主程式 main.c 檔。

#include ＜stdio.h＞
#include ＜stdlib.h＞
/*
 * include "自製標頭檔.h" 
 */
#include "./str.h"

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

int main(int argc, char *argv[])
{
	char *receive=str_include();
	printf("%s",receive);
	printf("%s",str_include());
	
	int send_parament=100;
	
	printf("%d",int_include(send_parament));
	
	
	return 0;
}

 

範例碼(二)：建立標頭檔，str.h 檔，並在主程式 main.c 檔引入。

char *str_include(void)
{
	char *str="自製標頭檔...\n";
	return str;
}

int int_include(int receive_parament)
{
	receive_parament=200;
	return receive_parament;
}

 

範例碼(三)：以上兩個(main.c , str.h)檔案經過前置處理器 #include 處理後，str.h 檔案會被合併進 main.c。

##include ＜stdio.h＞
#include ＜stdlib.h＞
/*
 * include "自製褾頭檔.h" 
 */
#include "./str.h"

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

char *str_include(void)
{
	char *str="自製標頭檔...\n";
	return str;
}

int int_include(int receive_parament)
{
	receive_parament=200;
	return receive_parament;
}

int main(int argc, char *argv[])
{
	char *receive=str_include();
	printf("%s",receive);
	printf("%s",str_include());
	
	int send_parament=100;
	
	printf("%d",int_include(send_parament));
	
	
	return 0;
}
//Answer:
//自製標頭檔...
//自製標頭檔...
//200
