Help me explain each line

Question

#include <iostream>
using namespace std;

int main() {
int n;
cin>>n; //size of the array
//your code goes here
int nums = 0;
cin>> nums;

int max = nums;
for(int i=0; i<n; i++) {
cin>> nums;
if(nums>max)
max = nums;
}
cout << max << endl;

return 0;
}

Answer 1

Instead of asking for each line explanation, can you tell which part or statement is not understood by you..?
do you know how to find maximum value from array?
