remove element from vector c++ by index

Code Example:

#include <iostream>
#include <vector>

int main() {
    std::vector<int> vec = {1, 2, 3, 4, 5};

    int indexToRemove = 2;
    vec.erase(vec.begin() + indexToRemove);

    for (int num : vec) {
        std::cout << num << " ";
    }

    return 0;
}

Explanation:

• Step 1: Include the necessary libraries for input/output operations and vectors.
• Step 2: Define the main function.
• Step 3: Create a vector of integers and initialize it with some values.
• Step 4: Define the index of the element to remove from the vector.
• Step 5: Use the erase function to remove the element at the specified index from the vector.
• Step 6: Iterate through the modified vector and print its elements.
• Step 7: Return 0 to indicate successful execution.
