Question

Write a simple program that pushes 25 random integers (you select the range) into a vector. Write a function that receives the vector as a parameter. Make that function add up all of the odd numbers in the vector and return the sum.

Answer 1

#include <iostream>
#include <vector>
#include <time.h>
using namespace std;

int sumVector(vector <int> g1){
vector <int> :: iterator i;
int total = 0;

for (i = g1.begin(); i != g1.end(); ++i)
total += *i;
return total;
}

int main()
{
// part a : declaring vector
vector <int> g1;
srand(time(NULL));
  
// elements into the vector
cout << "Elements in the vector are ";
for(int i=0; i<25; i++)
{
int randomNumber = rand() % 100 + 1;
g1.push_back(randomNumber);
cout << randomNumber << " ";
}
cout << endl;

cout << "Sum is " << sumVector(g1) ;
return 0;
}
