C++11 introduced uniform initialization syntax that allows initializing containers like std::vector in a concise and easy-to-read manner.
Instead of using the traditional constructor syntax, you can use the brace initialization syntax to initialize a std::vector using uniform initialization. This syntax uses a pair of braces {} to delimit the initialization list.
Here’s an example of how you can initialize a std::vector using uniform initialization:
#include <iostream>
#include <vector>
int main() {
// Initializing vector of integers using uniform initialization
std::vector<int> numbers = {1, 2, 3, 4, 5};
// Printing the vector elements
for (const auto& number : numbers) {
std::cout << number << " ";
}
std::cout << std::endl;
return 0;
}
In the code above, we first include the required headers (<iostream> and <vector>). Then, we declare a std::vector of integers named numbers and initialize it using uniform initialization with the values {1, 2, 3, 4, 5}.
Finally, we iterate over the elements of the vector using a range-based for loop and print each element to the console.
When you run the above code, it will output: 1 2 3 4 5, indicating that the vector has been successfully initialized using uniform initialization.
Uniform initialization provides a more modern and concise way to initialize containers like std::vector in C++. It simplifies the syntax and makes the code more readable.
