Question

How to apply an operation sequentially to vector elements in C++

Answer 1

#include <iostream>   
#include <algorithm>  
#include <vector>     

void printVector(std::vector<int> const &v) {
    for (int i = 0; i < v.size(); i++) {
        std::cout << v.at(i) << ' ';
    }
}

int addOne(int i) { 
    return ++i; 
}

int main () {
    std::vector<int> v = {10, 20, 30, 40, 50};

    std::transform(v.begin(), v.end(), v.begin(), addOne);
                                                 
    printVector(v);

  return 0;
}
