第18周OJ測試專案6--用數字造數字,oj6--輸入一個3位以上的整數,求其中最大的兩個數字之和與最小的數字之和之間的差。例如:輸入8729,輸出8,即(9+8)-(2+7)=8,再如,輸入24825,輸出9,即(8+5)-(2+2)=9。代碼如下:#include <iostream>using namespace std;int main(){int str[10];int i = 0, n, m, j, t;cin >> n;do{
Linux多線程實踐(1),linux多線程實踐線程概念在一個程式裡的一個執行路線就叫做線程(thread)。更準確的定義是:線程是“一個進程內部的控制序列/指令序列”;一切進程至少都有一個執行線程; 進程 VS. 線程 1.進程是資源分派(進程需要參與資源的競爭)的基本單位,而線程是處理器調度(程式執行)的最小單位;2.線程共用進程資料,但也擁有自己的一部分(非常少O(∩_∩)O~)資料,如線程ID、程式計數器、一組寄存器、堆棧、
