Adding all value to total in for loop - c++

Question

I'm new to coding. I wrote the below code in C++ and I am not allow to use array.
You will create a console C++ program that uses a nested loop to enter each archer's individual end scores and then displays the total score for each archer.
I am stuck at how to calculate the total end score:
#include <iomanip>
using namespace std;
int main()
{
int Rounds = 4;
int Archers = 3;
int endScore ;
int average;
for (int a = 1; a <= Archers ; a++)
{
cout << endl << "Number " << a << " score" << endl;
int tEndScore = 0 ;
for(int i=1; i <=Rounds ; i++)
{
cout << "Round " << i << " : " ;
cin >> endScore;
while(cin.fail())
{
cout << endl << "not enter an integer " << endl ;
cout << "Please enter an integer ";
cin >> endScore;
}
tEndScore += endScore;
}
cout << endl << "The total score for 4 ends of Archer Number " << a << " is " << tEndScore << endl;
average =(double) tEndScore/Rounds;
cout << setiosflags(ios::fixed) << setprecision(2) << endl << "The average score of 4 ends of Archer Number " << a << " is " << average << endl;
}
}
This is the result after running. It will only use the last value I entered as tEndScore:

You need to shift tEndScore =+ endScore; this line inside the second for loop as
for(int i=1; i <=Rounds ; i++)
{
...
...
tEndScore += endScore;
}
And it will be a good practice (And mandatory for your code...) to initialize the tEndScore for each player as
for (int a = 1; a <= Archers ; a++)
{
tEndScore = 0;
endScore = 0;
average = 0;
...
...
}
You need to replace totalEndScore to tEndScore and totalRounds to Rounds.
