fill_n 으로 값을 채우기

int testArray[10][10] = {0,}; fill_n(*testArray, 4, 5); for(int i=0; i<10; i++){ for(int j=0; j<10; j++){ cout << testArray[i][j] << " "; } cout << endl; } fill_n(*testArray, 10*10, 5); for(int i=0; i<10; i++){ for(int j=0; j<10; j++){ cout << testArray[i][j] << " "; } cout << endl; }

result :

|| 5 5 5 5 0 0 0 0 0 0 || 0 0 0 0 0 0 0 0 0 0 || 0 0 0 0 0 0 0 0 0 0 || 0 0 0 0 0 0 0 0 0 0 || 0 0 0 0 0 0 0 0 0 0 || 0 0 0 0 0 0 0 0 0 0 || 0 0 0 0 0 0 0 0 0 0 || 0 0 0 0 0 0 0 0 0 0 || 0 0 0 0 0 0 0 0 0 0 || 0 0 0 0 0 0 0 0 0 0 || 5 5 5 5 5 5 5 5 5 5 || 5 5 5 5 5 5 5 5 5 5 || 5 5 5 5 5 5 5 5 5 5 || 5 5 5 5 5 5 5 5 5 5 || 5 5 5 5 5 5 5 5 5 5 || 5 5 5 5 5 5 5 5 5 5 || 5 5 5 5 5 5 5 5 5 5 || 5 5 5 5 5 5 5 5 5 5 || 5 5 5 5 5 5 5 5 5 5 || 5 5 5 5 5 5 5 5 5 5
