运行C++时总出现错误 ,请问是什么问题

程序名:
test1.C

代码如下:

#include <stdio.h>



void my_print(char *string);

void my_print2(char *string);



main()

{

char my_string[]=”Hello embedded Linux world”;



my_print(my_string);

my_print2(my_string);

}



void my_print(char *string)

{

printf(“The string is &s\n”,string);

}



void my_print2(char *string)

{

char *string2;

int size,i;



size=strlen(string);

string2=(char *)malloc(size+1);

for(i=0;i<size;i++) {

string2[size-i]=string[i];

}

string2[size+1]=’\0’;

printf(“The string printed backward is %s\n”,string2);

}



运行命令:
# g++ -o test1 test1.C

错误如下:

C++用#include <stdio.h>？建议用#include <iostream>
从错误信息来看，应该是用了不合适的符号所致。

字串是不是用了全角的引号；
另外把strlen和malloc的头文件加进去

代码是从其他地方复制的么?比如网页上
多了一些无法认出的字符....
原来也碰到过
把出现问题的行的空格删掉重敲试试

谢谢你们的热心帮助：）

该错误是指源程序中有非法字符，需要去掉非法字符。一般是由于从别的地方粘贴过来造成的。

把所粘的文字放到记事本里就行了
