練習(xí)34 指針數(shù)組 多重指針

//通過指針數(shù)組操作元素#includeint main(){int a = 16, b = 55, c = 100;//定義一個(gè)指針數(shù)組int *arr[3] = { &a, &b, &c };//也可以不指定長(zhǎng)度，直接寫作 int *arr[]
//定義一個(gè)指向指針數(shù)組的指針int **parr = arr;printf("%d, %d, %d\n", *arr[0], *arr[1], *arr[2]);

printf("%d, %d, %d\n", **(parr + 0), **(parr + 1), **(parr + 2));printf("%d, %d, %d\n", *parr[0], *parr[1], *parr[2]);//**(parr + 0) 等價(jià) *parr[0]

//指針數(shù)組還可以和字符串?dāng)?shù)組結(jié)合使用char *str0 = "hello world";char *str1 = "test";char *str2 = "C Language";char *str[3] = { str0, str1, str2 };printf("%s\n%s\n%s\n", str[0], str[1], str[2]);printf("%s\n%s\n%s\n", *(str + 0), *(str + 1), *(str + 2));// *(str + 0) 等價(jià) str[0]
return 0;}
