try:
12345678<br /><br />#include <br />void main()<br />{<br />printf("nHello Worldn");<br />}<br />Is the code to be in c or c++? If in C++ you could easily type the proper combinations of input ( for the first line for example ):
123456<br />inputFile >> word; //get "Training"<br />inputFile >> word;//get "File"<br />inputFile >> word// get "="<br />inputFile.getline ( fileString , MAX_LENGTH , 'n' ); //get ".ts_ce_D_0.5-1.5_train3.sdf"<br />simple but tedious ………
The average is calculated in the line:
123<br />printf ( "The miles/gallon for this tank was : %f n" , miles / gallons );<br />the compiler sets up a hidden temporary variable to hold the result of ( miles/gallons ) and then sends this result to the printf () function to print it……..
If your in the main function you could just use a return statement , I’d have to see the code , though…

You can change this by changing the number listed after the ‘.’ in the last printf() statements.
Theres an error in the code I posted for the approximation of e = 1 + 1/1! + 1/2! . Heres the proper code:

Is the list to be “disconnected” for sorting ( structs will be moved and the list reconnected ) or is data to be shifted ( probably easier )…
