一、實現(xiàn)功能：

輸入表示年齡的數(shù)字，將其轉化為英文

二、相關知識：

1、數(shù)組
2、條件語句

三、代碼實現(xiàn)

#include <stdio.h>
//輸入年齡轉化為對應英文
//數(shù)組相關知識 
int main(){
    int age = 0;
    //保存?zhèn)€位數(shù) 
    char* gewei[] = {"","one","two","three","four","five","six","seven","eight","nine"}; 
    //保存10—19
    char* temp[] = {"ten","eleven","twelve","thirteen","fourteen","fifteen","sixteen","seventeen","eighteen","nineteen"}; 
    //保存十位數(shù)
    char* shiwei[] = {"twenty","thirty","forty","fifty","sixty","seventy","eighty","ninty"};
    
    printf("請輸入年齡：");
    scanf("%d",&age);
    
    char *name;//保存每次取出的字符串 
    if(age < 10){
        name = gewei[age];
    }else if(age >= 10 && age <= 19){
        //獲得個位數(shù)
        int index = age % 10;
        name = temp[index]; 
    } else{
        //獲取個位數(shù)
        int g = age % 10;
        //獲取十位數(shù) 
        int s = age / 10;
        //取出對應的單詞
        char* sString = shiwei[s-2];
        char* gString = gewei[g];
        
        printf("your age is %s-%s\n",sString,gString);
        //程序還未運行完畢提前結束 
        return 0;
    }
    printf("your age is %s",name);
    return 0;
} 

四、運行結果：

1、1到9歲

2、10到19歲

3、20到99歲

五、注意點：

1、變量類型不可前后矛盾需要仔細（int 與 char*）

2、條件語句中不需要執(zhí)行完畢直接結束可在該條件執(zhí)行完畢后中止程序，直接 return 0

3、各位與十位數(shù)分開存放在不同數(shù)組調用的思想

4、取整/ 與 取余%

取整決定十位數(shù)
取余求各位

數(shù)組相關知識在后面學習
