how to create a vector in c++
// CPP program to create an empty vector
// and push values one by one.
#include <vector>
using namespace std;
int main()
{
// Create an empty vector
vector<int> vect;
//add/push an integer to the end of the vector
vect.push_back(10);
//to traverse and print the vector from start to finish
for (int x : vect)
cout << x << " ";
return 0;
}how to create a vector in c++
// First include the vector library:
#include <vector>
// The syntax to create a vector looks like this:
std::vector<type> name;
// We can create & initialize "lol" vector with specific values:
std::vector<double> lol = {66.666, -420.69};
// it would look like this: 66.666 | -420.69how to make a vector in c++
#include <vector>
using namespace std;
int main(){
vector<int> v;
//vector<type> name
return 0;
}create vectors of vectors c++
typedef std::vector<std::vector<double> > Matrix;
Matrix matrix = { {0.1,1.1,.2},
{.4,.5,.6},
{.8,.9,.10}
};
// Just initilization:
int rows = 3;
int cols = 3;
Matrix m3(rows, std::vector<double>(cols) );Copyright © 2021 Codeinu
