How can I modify the code to input the second columns of the following data file into array x[N]
VELOCITY
3 4 5
4 5 6
...N
x[] = 4, 5 ...N
ThanksCode:int main(){ double x[N]; ifstream in("file.txt"); int i = 0; while (i < N && in >> x[i]) { i++; } }
Read in a line at a time (3 values), throw away (or do something else with) the two values you don't want and store the other (the 2nd column):
Code:double temp1, temp2; while( i < N && in >> temp1 >> x[i] >> temp2 ) { ++i; }
"Owners of dogs will have noticed that, if you provide them with food and water and shelter and affection, they will think you are god. Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."
