    Use == to test for equality with strings just like built in types.

    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

    Code:
    int main(){
    
    	double x[N];
    
    	ifstream in("file.txt");
    
    	int i = 0;
    	while (i < N && in >> x[i])
    	{
    		i++;
    	}
    }
    Thanks

    That's a totally different question, so start a new thread.

    Also, it looks like homework.
    All the buzzt!
