  You can access vector data in C++ by declaring a vector variable and using its member functions. First, include the <vector> header file. Then, declare a vector variable with the desired data type, such as vector<double> for storing cryptocurrency prices. You can add elements to the vector using the push_back() function, and access elements using the [] operator or the at() function. To perform analysis on the vector data, you can use various algorithms and functions provided by the C++ standard library, such as sorting, searching, and statistical calculations. Example: #include <vector> #include <iostream> int main() { std::vector<double> prices; prices.push_back(100.5); prices.push_back(200.3); prices.push_back(150.7); std::cout << "First price: " << prices[0] << std::endl; std::cout << "Number of prices: " << prices.size() << std::endl; // Perform analysis on the vector data // ... return 0; }
