stock a file in a vector cpp

To stock a file in a vector in C++, you can follow these steps:

  1. Include the necessary header files:
#include <iostream>
#include <fstream>
#include <vector>

Here, we include the necessary header files. The iostream header is required for input/output operations, fstream is needed for file handling, and vector is used to store the contents of the file.

  1. Create an input file stream object and open the file:
std::ifstream inputFile;
inputFile.open("filename.txt");

Here, we create an input file stream object called inputFile and open the file "filename.txt". Make sure to replace "filename.txt" with the actual name of the file you want to stock in the vector.

  1. Create a vector to store the file contents:
std::vector<std::string> fileContents;

Here, we create a vector called fileContents to store the contents of the file. In this example, we assume that each line of the file contains a string.

  1. Read the file line by line and store each line in the vector:
std::string line;
while (std::getline(inputFile, line)) {
    fileContents.push_back(line);
}

Here, we use a while loop to read each line of the file using the getline function. The getline function reads a line from the file and stores it in the line variable. Then, we use the push_back function to add the line to the fileContents vector.

  1. Close the file:
inputFile.close();

After reading the file, it is important to close it using the close function to free up system resources.

Now, the fileContents vector contains all the lines of the file. You can access and manipulate the contents as needed.
