一般来说，字符里面比如'.'含有空格的话，会提示这个警告，但仍然能编译通过。尽管C语言提供了许多低级处理的功能，但仍然保持着良好跨平台的特性，以一个标准规格写出的C语言程序可在许多电脑平台上进行编译，甚至包含一些嵌入式处理器（单片机或称MCU）以及超级电脑等作业平台。
In this program, we have defined a constant character type variable “*c” and have assigned to it the value “123”. After that, we defined an integer “x”. Then, we used the “sscanf” function to convert the value of “c” to an integer and save it to “x”. Finally, we ha...

1、如果要将string转换为char*，可以使用string提供的函数c_str() ，或是函数data()，data除了返回字符串内容外，不附加结束符'\0'，而c_str()返回一个以‘\0’结尾的字符数组。2、const char *c_str();c_str()函数返回一个指向正规C字符串的指针,内容与本string串相同.这是为了与c语言兼容...
