七种循环方式实现题目

题目:有10亿元,每天花一半,可以花多少天?

第一种:

int count = 0;for (int money = 1000000000; money > 0; money /= 2) {     cont++;}System.out.println(cont - 1);

第二种:

int count = -1;int money = 1000000000;while (money >= 1) {     count++;    money = money / 2; }System.out.println(count);

第三种:

int count = -1;int money = 1000000000;for (; money > 0; ) {     count++;    money /= 2; }System.out.println(count);

第四种:

int count = -1;int money = 1000000000;for (;;) {     count++;    money /= 2;    if (0 == money) {        break;     }} System.out.println(count);

第五种:

int count = -1;int money = 1000000000; while (true) {    count++;    money /= 2;    if (0 == money) {        break;    }} System.out.println(count);

第六种:

int count = -1;int money = 1000000000; do {    money /= 2;     count++;} while (money > 0); System.out.println(count);

第七种:

int count = 0;int money = 1000000000; do {    money /= 2;} while (money > 0 && count++ >= 0); System.out.println(count);
