Answer to Question #301176 in C++ for Norri

Question

How to execute this using vector

#include <iostream>

bool doesexists(int array[], int toseaarch, int size);

const short int SIZE = 10;

int main() {

int myarray[SIZE], distinct_ctr = 0, index = 0;

std::cout << "Enter 10 numbers: ";

for (index = 0; index < SIZE; index++) {

int tmp;

std::cin >> tmp;

if (!doesexists(myarray, tmp, SIZE)) {

myarray[distinct_ctr] = tmp;

distinct_ctr++;

}

}

std::cout << "distinct numbers are: ";

for (index = 0; index < distinct_ctr; index++)

std::cout << myarray[index] << " ";

std::cout << "\n";

return 0;

}

bool doesexists(int array[], int toseaarch, int size) {

for (int index = 0; index < size; index++) {

if (toseaarch == array[index])

return true;

}

return false;

}

Answer 1

#include <iostream>
#include <vector>

using namespace std;

bool doesexists(vector<int> vec, int toseaarch, int size);

const short int SIZE = 10;

int main() {
  vecotr<int> myvec(SIZE), distinct_ctr = 0, index = 0;
  cout << "Enter 10 numbers: ";
  for (index = 0; index < SIZE; index++) {
    int tmp;
    cin >> tmp;
    if (!doesexists(myvec, tmp, SIZE)) {
      myvec[distinct_ctr] = tmp;
      distinct_ctr++;
    }
  }
  cout << "distinct numbers are: ";
  for (index = 0; index < distinct_ctr; index++) {
    cout << myvec[index] << " ";
  }
  cout << "\n";
  return 0;
}

bool doesexists(vector<int> vec, int toseaarch, int size) {
  for (int index = 0; index < size; index++) {
    if (toseaarch == vec[index])
      return true;
  }
  return false;
}
