Decimal Values & ANSI C Code for Image File

AI Thread Summary
The discussion revolves around coding in ANSI C to read and process a structured file containing decimal values. The user seeks assistance in reading the first line, printing it, and then reading subsequent lines to sum specific values. A suggestion is made to utilize the `scanf` function for input, specifically using `scanf("%d %c %f", &a, &b, &c)` for the header line and a loop with `scanf("%f %f %f %f %f", &d, &e, &f, &g, &h)` for the data lines. Additionally, it is recommended to create separate functions for clarity, such as `readHeaderLine` and `readDataLine`, which can return values to indicate when a data set is finished or when no more data sets are available. This modular approach aims to simplify the main loop and enhance code organization.

Hi, I have a problem to code this:

Image that you have the following file presenting the following decimal values:

2 A 40.0
115.00 1.02842 5.944 10.0528 -1.656
115.00 1.01911 4.678 10.0528 177.078

11 6 100.0
115.00 1.01530 2.392 2.9097 11.933
115.00 1.00338 2.849 0.2633 37.685
115.00 1.00566 2.460 1.5274 8.387
230.00 0.99738 5.209 4.3274 -2.728

How can I code in ANSI C so that the program reads the first line, prints it ( I know this part) then reads the following 5 ( which are the values for voltages) add all of them, then goes to to the second ste of five data.

After thatthe program reads the second set of three data, print them, and reads the follwoing five, add them all and so forth.

can some help me or give me some suggestions
Thank you

Do you know how to use the scanf function?

For the first line you can do:

scanf("%d %c %f",&a, &b, &c) ;

Then for the the rest of the lines you have a for loop that does this:

scanf("%f %f %f %f %f",&d, &e, &f, &g, &h) ;

Thank you
My problem was where to start the loop.

My suggestion is that you write separate functions for each separate task, which helps make everything much clearer. For example, write function "readHeaderLine" to process the top line of each data set and write function "readDataLine" to read and process each data line. If these functions return a value like the number of items processed then you can make them return 0 when they come across an empty line. This way your main function will know when a data set is finished (readDataLine has returned 0) or when there is no more data sets to process (readHeaderLine has returned 0). Using these accessory functions, you will find it simple to write the main loop.
 
Thread 'Is this public key encryption?'
I've tried to intuit public key encryption but never quite managed. But this seems to wrap it up in a bow. This seems to be a very elegant way of transmitting a message publicly that only the sender and receiver can decipher. Is this how PKE works? No, it cant be. In the above case, the requester knows the target's "secret" key - because they have his ID, and therefore knows his birthdate.
