C Write a loop that subtracts 1 from each element in lowerSc

C++ Write a loop that subtracts 1 from each element in lowerScores if the original element was greater than 0, and otherwise just assigns the element with 0. Ex: lowerScores = {5, 0, 2, -3} becomes {4, 0, 1, 0}.

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

int main() {
const int SCORES_SIZE = 4;
vector<int> lowerScores(SCORES_SIZE);
int i = 0;

lowerScores.at(0) = 5;
lowerScores.at(1) = 0;
lowerScores.at(2) = 2;
lowerScores.at(3) = -3;

/* Your solution goes here */

for (i = 0; i < SCORES_SIZE; ++i) {
cout << lowerScores.at(i) << \" \";
}
cout << endl;

return 0;
}

Solution

#include <iostream>
#include <vector>
using namespace std;
int main() {
const int SCORES_SIZE = 4;
vector<int> lowerScores(SCORES_SIZE);
int i = 0;
lowerScores.at(0) = 5;
lowerScores.at(1) = 0;
lowerScores.at(2) = 2;
lowerScores.at(3) = -3;
/* Your solution goes here */
for (i = 0; i < SCORES_SIZE; ++i) {
if(lowerScores.at(i)>0)
lowerScores.at(i)=lowerScores.at(i)-1;
else
lowerScores.at(i)=0;
}
for (i = 0; i < SCORES_SIZE; ++i) {
cout << lowerScores.at(i) << \" \";
}
cout << endl;
  
return 0;
}
