I am doing a C++ program in Xcode and keep getting the following build failure (even though it runs fine on my terminal):

Showing Recent Issues

clang: error: linker command failed with exit code 1 (use -v to see invocation)

I believe the issue may be with iostream or cstdio libraries.

Code below:

#include

#include

using namespace std;

double findAverageScore(int scores[], int numJudges){

//3 double

double highest = 0;

double lowest = scores[0]; //NOTE: lowest set to 1st index

double total = 0;

for(int i = 0; i < numJudges; i++){

total += scores[i];

if(scores[i] >= highest){

highest = scores[i];

}

if(scores[i] <= lowest){

lowest = scores[i];

}

}

total = total - highest - lowest;

return total/(numJudges - 2);

}

int main(){

//4 int and 1 double

int N; //number of judges

int contestant;

int highestContestant = 0;

int highScore = 0;

double averageScore;

printf("Enter the number of judges: ");

cin >> N;

int scores[N];

printf("Number of judges entered: %d", N);

while(true){

printf("Enter the contestant number: ");

cin >> contestant;

if(contestant > 0){

puts("Enter scores: ");

for(int i = 0; i < N; i++){

cin >> scores[i];

}

averageScore = findAverageScore(scores, N);

if(averageScore >= highScore){

highestContestant = contestant;

highScore = averageScore;

}

}else{

printf("Contestant %d had the highest score ", highestContestant);

break;

}

}

return 0;
