Help Scanning File Data In C

Homework Statement

Ok, here is the other question that's giving me a headache. There is a file which holds 5 data items per line and a minimum of 1 line. The data is always in the order float float integer float string and each element is separated by a space. So we need to ask the user for a file name and then we need to output the data to the user in a user friendly way. It let's me compile but after it prints out everything i get a stack smashing detected error which I have no clue as to its meaning. We just learned pointers and how to open and read files and stuff and I am very confused. We were never taught fgets in class so I tried to teach myself on the net so I am a little confused. It let's me put the whole contents of the file I'm reading into a 20 character array i made called weatherFile?

I also somehow need to print off each individual data item with several spaces in between instead of single spaces like how the original file is to make it more user friendly and I'm not sure how to do that with the way I have it written now. So if someone can take a look at the program I have so far and help me, it would be very greatly appreciated. Thanks for your time! :)

I can understand how challenging programming can be, especially when learning new concepts like pointers and file handling. It is important to first make sure that your code is syntactically correct and free of any errors. In this case, the stack smashing error could indicate a memory issue, possibly caused by using an array that is too small to hold all the data from the file.

Additionally, when reading data from a file, it is important to check for any potential errors or invalid data. One way to do this is by using the fgets function, which reads a line from a file and stores it in a string. You can then use string manipulation functions to extract the individual data items from the string.

To make the output more user-friendly, you can use the printf function to format the data before printing it to the screen. For example, you can use the %10f format specifier to print a float with 10 spaces between each item.

Overall, it is important to carefully review your code and make sure it is logically sound and free of any potential errors. It may also be helpful to seek assistance from a classmate or a tutor to better understand the concepts and techniques involved in this task. Good luck!
