如何使用strcmp来解决这个问题？

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！

回复 2楼 qq1023569223

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

程序代码：

#include<stdio.h>
#include<string.h>

int language ()
{
    int n, i = -1;
    char input_month[10];
    char Chi_month[12][10]={"yiyue","eryue","sanyue","siyue","wuyue","liuyue","qiyue","bayue","jiuyue","shiyue","shiyiyue","shieryue"};
    char Eng_month[12][10]={"January","February","March","April","May","June","July","Augest","September","October","November","December"};

    puts("This program will access a month's index by its name,u can search in two languages: Finnish and English");
    puts("0-Pingyin");
    puts("1-English");
    printf(">> ");
    scanf("%d",&n);
    puts("Enter the month name in the language u selected.");
    printf(">> ");
    fflush(stdout);
    scanf("%s", input_month);

    switch(n)
    {
    case 0:
        for (i=0;i<12 && strcmp( input_month, Chi_month[i]) != 0;i++);
        break;
    case 1:
        for (i=0;i<12 && strcmp( input_month, Eng_month[i]) != 0;i++);
        break;
    default:
        printf("Illegal selection! Plz only choose 0 or 1.");
    }
    if (i < 12) {
        printf("Your month is month number %d",i+1);
    } else {
        i = -1;
    }
    return i;
}

int main(void)
{
    int n;
    n = language ();
    return 0;
}
