How to remove a subvector from a vector in C++

Answer 1

#include <iostream>
#include <vector>

int main() {
    std::vector<int> vec = {1, 2, 3, 4, 5, 6, 7, 8, 9};

    // Define start and end indices
    int startIndex = 2; // 0-based index
    int endIndex = 5;   // Exclusive

    // Remove elements from startIndex to endIndex
    vec.erase(vec.begin() + startIndex, vec.begin() + endIndex);

    // Print the updated vector
    for (int num : vec) {
        std::cout << num << " ";
    }
}



/*
run:
 
1 2 6 7 8 9 
 
*/
