Raspberry Pi 3B+

1. Raspberry Pi executes the .c file

1. Create the file using the command nano helloworld.c commandnano hello.c
2. Edit the code as follows
   

#include <assert.h>
#include <stdio.h>
 
int main()
{
    
    
   int x;
   char str[40];
     
   printf("请输入一个大于10整数值： ");
   scanf("%d", &x);
   assert(x > 10);
   printf("输入的整数是： %d\n", x);
    
   printf("请输入字符串： ");
   scanf("%s", str);
   assert(str != NULL);
   printf("输入的字符串是： %s\n", str);
    
   return(0);
}

3. Use the gcc tool to compile and run
   to compile in one step:gcc hello.c -o hello

4. run:./hello
   

2. Use the scp command to practice file copy and transfer

1. File content on Ubuntu
   

2. Use the command scp on Ubuntu

scp 本地Linux系统文件路径 远程用户名@IP地址：远程系统文件绝对路径名
