std::mapmy_map; // TypeA key; TypeB value my_map.insert({ key, value }); // insert elements in random order
Here is what the above code is Doing:
1. Create a map called my_map.
2. Insert a key-value pair into my_map.
std::mapmy_map; // TypeA key; TypeB value my_map.insert({ key, value }); // insert elements in random order

“std” is an abbreviation for standard. Here is what the above code is Doing: 1. We import the pandas library as pd. 2. We import the numpy library as np. 3. We read a CSV called “winequality-red.csv” into a DataFrame called wine_df. 4. We print the first five rows of wine_df. 5. We print the…
for (int i = 10; i > 0; –i) { Here is what the above code is Doing: 1. We’re creating a for loop that will run 10 times. 2. We’re printing out the value of i each time the loop runs. 3. We’re decrementing i by 1 each time the loop runs.
getline(cin, variable_name, ‘\n’); Here is what the above code is Doing: 1. We’re creating a string variable called variable_name. 2. We’re using the getline function to get input from the user. 3. We’re using the cin object to get the input from the user. 4. We’re using the ‘\n’ character to tell the getline function…
std::set myset; myset.erase(value); Here is what the above code is Doing: 1. Create a set called myset. 2. Erase the value value from myset. If the value value is not found, the set is left unchanged.
void BSNode::insert(std::string value) { if (this->_data == value) { _count++; return; } if (this->_data > value) { if (this->getLeft() == nullptr) { this->_left = new BSNode(value); } this->getLeft()->insert(value); return; } if (this->getRight() == nullptr) { this->_right = new BSNode(value); return; } this->getRight()->insert(value); } Here is what the above code is Doing: 1. If the value…
