题目:程序让用户选择语言，如果输入的月份与字符串数组的月份相同(如我输入May，则与char Eng_month内的May相同，则返回（i=4）).  0为拼音，1为英文，程序必须使用一个函数，它调用2个参数，分别是字符串数组和字符串。函数返回相等的那个月份的index(如我输入May，则与char Eng_month内的May相同，则返回（i=4），若没在字符串里发现，则返回-1，要使用strcmp.

PS：我大约只能写这么多了，求助！，谢谢！

        break;
    default:

楼上同学，抱歉，我漏打一句，程序要使用另一个函数，它调用2个参数，分别为字符串数组和整数，整数参数决定语言选择，这个函数初始化选择语言的月份名数组
