1.整理思维导图
2.做一套笔试题
一:
1.cd ..
mkdir dir1
cd dir1
touch file1
2.cp ~/mnt/dir1/ -r * ~/home/dir2/
3.pwd
4.ls -l
5.ifconfig
6.top
10.find /usr -type f -name "*name*"
11.:wq
13.df -h
14.tar -xzvf tmp.tar.gz
15.sudo chmod 765 tmp
二:
1.(1)19 (2) 4 (3)100 (4)4
2.3
3.
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;int main()
{string a = "1234a";for (char c : a) {cout << hex << setw(2) << setfill('0') << static_cast<int>(c) << " ";}cout << endl;return 0;
}
4.x=58 y=96
5.(1)1 (2) 0 (3)1 (4)1 (5)4
