Answer:
// CPP program to Convert characters
// of a string to opposite case
#include<iostream>
using namespace std;
// Function to convert characters
// of a string to opposite case
void convertOpposite(string &str)
{
int ln = str.length();
// Conversion according to ASCII values
for (int i=0; i<ln; i++)
{
if (str[i]>='a' && str[i]<='z')
//Convert lowercase to uppercase
str[i] = str[i] - 32;
else if(str[i]>='A' && str[i]<='Z')
//Convert uppercase to lowercase
str[i] = str[i] + 32;
}
}
// Driver function
int main()
{
string str = "GeEkSfOrGeEkS";
// Calling the Function
convertOpposite(str);
cout << str;
return 0;
}

Answer:
b. mkdir -p ~/2019projects/project/projectplans
Explanation:
mkdir command in Linux environment is used to create a new directory. This command is used to create a folder to store the information in organized manners.
-p is used to create a parent folder in the directory. If we want to start a new project or want to store information about some new topic we will create a new folder for that purpose. So, -p is used to create a new folder in directory.
In above mentioned case, this is the first project that Mindy started in 2019, so she should create a parent directory of 2019 to save all projects details that she worked in 2019. So she should use -p with mkdir command to make 2019 as a parent folder.
