we inserted the “int main()” function, and then we initialized a string with the name “my_str,” and we didn’t add any size of the string here. The string we used for initializing “my_str” is “String
char型是字符型，不能是int类型。176，219均是int型的，故会报错。改法，第一种可以把char改成int；第二种可以改a='176',b='219'; 不过话说你就直接输出这几个数干嘛？？？真心搞不懂找个程序是干嘛的一般都会printf%d和%c交替然后查看字符对应的asc码和字符本身这程序谁写的？想干什么
警告：c4305初始化：截断从const int”字符 c++ 整数默认是 int（32 位系统位 4 字节） 类型，赋值给 char 类型，将可能面临数据截断问题。解决方法有两种：一是强制转换，如将数据写成 (char)0x40；另外一种方法是不予理会，如果觉得出现警告烦人，可以再出现警告地方的前面，加上杂注：pragma warnin...

建议，拷贝全部项目，而不是只拷贝代码。某些项目编译需要编译器的设置，光拷贝代码，而不知道以前编译时的设置，通常都会出错
