How do I fix this? **the code I've written is written in the answer section*****

Question

I want to first display the length of the vector and I used the size function
And now I want to use the printVect function to show the vectors. But I want to use pointers in displaying it.

This is what I have so far. I'm using c++

Answer 1

printVec expects 2 parameters and in main you are calling it with just 1 parameter.
Remove "s" from where you declared printVec

Answer 2

#include <iostream>
#include <vector>
using namespace std;

int size (vector<int> nums)
{
cout << nums.size();
return 0;
}

int printVec(vector<int>* nums, int s[])
{
for (int i=0; i<nums->size(); i++)
{
cout << (*nums)[i] << endl;
}
}

int main() {
vector<int> nums {77, 4, 12, 55, 98};
size(nums);
printVec(&nums);
return 0;
}
