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.

Question

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);

unsigned int i;

for (i = 0; i < lowerScores.size(); ++i) {

cin >> lowerScores.at(i);

}

/* Your solution goes here */

for (i = 0; i < lowerScores.size(); ++i) {

cout << lowerScores.at(i) << " ";

}

cout << endl;

return 0;

}

Answer 1

using namespace std;

#include <iostream>

int main() {

const int SCORES_SIZE = 4;

int lowerScores[4];

for (int i = 0; i < SCORES_SIZE; i++)

{

cout << "Please input the score :>";

cin >> lowerScores[i];

}

for (int i=0; i<SCORES_SIZE; i++)

{

if (lowerScores[i]>0)

{

lowerScores[i]--;

}

else

{

lowerScores[i]=0;

}

}

for (int i = 0; i < SCORES_SIZE; i++)

{

cout << lowerScores[i]<< " ";

}

cout << endl;

return 0;

}
