Question

C++

Write a loop that subtracts 1 from each element in lowerScores. If the element was already 0 or negative, assign 0 to the element. Ex: lowerScores = {5, 0, 2, -3} becomes {4, 0, 1, 0}.

#include <iostream>
using namespace std;

int main() {
const int SCORES_SIZE = 4;
int lowerScores[SCORES_SIZE];
int i;

for (i = 0; i < SCORES_SIZE; ++i) {
cin >> lowerScores[i];
}

/* Your solution goes here */

for (i = 0; i < SCORES_SIZE; ++i) {
cout << lowerScores[i] << " ";
}
cout << endl;

return 0;
}

Answer 1

#include <iostream>
using namespace std;

int main() {
const int SCORES_SIZE = 4;
int lowerScores[SCORES_SIZE];
int i;

for (i = 0; i < SCORES_SIZE; ++i) {
cin >> lowerScores[i];
}

for (i = 0; i < SCORES_SIZE; ++i) {
   if(lowerScores[i]>0)
      lowerScores[i]-=1;
   else
       lowerScores[i]=0;
}

for (i = 0; i < SCORES_SIZE; ++i) {
cout << lowerScores[i] << " ";
}
cout << endl;

return 0;
}
