Hi experts, This is my college project..i have tried it a lot of times but compilation keeps failing and i have run out of idea...please somebody if u see this..please give a helping hand...i appreciate very very much if someone could help...the question is as follows: • Define a structure with the following data members: • studid (use char array of 10 elements to store the Student ID) • lectatt (use int array of 14 elements to store 14 weeks of lecture attendance). • Use the preprocessor directive to define constants for elements in both arrays. • In main() function : • Declare an array of structure variable mystudents with 7 elements. Use the preprocessor directive to define the constant for this array also. • Declare a pointer to a file called input_file. • Declare and initialize the following arrays of variable. o hours_attended (total hours attended for each students) o att_percentage (the percentage of attendance based on the assumption that students need to attend 2 hours of lecture every week) • Use the fopen() function call to open a file named attendance.dat for read only and assign the return value the pointer of the input_file. • Check whether the attendance.dat can be open or not. • If the file can be opened, use a nested for loop the insert data in the array of structure mystudents. o Use the outer for loop to read the Student ID and insert the data into the structure array. o Use the inner for loop to read the attendance where each number represent the number of hours attended. • Close the input file. • Create another nested for loop just like the first nested loop to get the total hours attended and get the percentage (assuming that students need to attend 2 hours every week for 14 weeks). • Use the last for loop to display the Student ID and the attendance percentage for each student. Thanking you in advanced, and best regards, C programming Student
Did you try to write the whole lot in one go before compiling it? This seems a very common beginner mistake. NOBODY writes code that way - except beginners. So: In main() function : Declare an array of structure variable mystudents with 7 elements. Use the preprocessor directive to define the constant for this array also. Stop right there. Before you go any further do you love me? Oops, sorry, got into a Meatloaf song there. Um, before you go any further, compile it. Any errors? Fix them. Now: Declare a pointer to a file called input_file. Stop again. Compile it. Any errors? Fix them. And so on. Baby steps; that's the only way to write code. As you get more experience, your baby steps get bigger, but not much. I started programming in 1981 and I still don't write more than 10-15 lines of code before getting the compiler's opinion on what's happening. All my programs start with a "Hello world", when that works OK I then get on and write a bit of code.
hi xpi0t0s, Thanks alot for your advise. I've figured out the solution and get it done on time. Thanks for everything. Take care^^ Best and Warmest regards, SAM
