error: ‘gets’ was not declared in this scope gets(str);

PAT中:
error: ‘gets’ was not declared in this scope
            gets(str);

error: ‘gets’ was not declared in this scope      gets(str);
原因:
gets()方法已经不被PAT编译器支持了,因此要采用其他方法。
header添加:
         #include <iostream>
         using namespace std;
将gets(str);改为:
         cin.get(str,n);//n为str数组的长度
