Answer to Question #74859 in C for jw

Question

how to change the code so that it can sort

struct SResult sample[] = { {"A1234", 10}, {"A1239", 5}, {"A1394", 7}, {"A1434", 3}, {"A1454", 5}, {"A2884", 7}, {"A3235", 7}, {"A4334", 9}, {"A4884", 2}, {"A6934", 5}, {"A7265", 7}, {"A9559", 3} };

void counting_sort(struct SResult scoreArr[], int N, int final[]) {

int freq[11] = {0}, cfreq[11] = {0};
int i, curScore;

//1. Compute Frquency
for (i = 0; i < N; i++){
freq[ scoreArr[i].score ] ++;
}

//2. Compute Cumulative Frequency
cfreq[0] = freq[0];
for (i = 1; i < 11; i++){
cfreq[i] = cfreq[i-1] + freq[i];
}

//3. Produce Final Position
for (i = 0; i < N; i++){
curScore = scoreArr[i].score;
final[ cfreq[ curScore ] - 1 ] = curScore;
cfreq[curScore]--;
}
}
