cloop | C-Style For-Loops for Python | Code Editor library

I am currently studying computer architecture, and we got the task of writing the code of the Greatest Common Divisor with these assembler rules:

I'm trying to get the values of two attributes from table MVR_DTL in column VENDOR_XML. VENDOR_XML is of datatype clob and contains an xml that looks like this

I'll try to make this short. I am running into an infinite loop issue with my program and even after trying to use the debugger I am having issues with an infinite loop.

The program I am trying to make is an assignment from my instructor, to sort through a table of IP addresses that use .word. I have the program done about 95% the last issue I am having is when I type in 193.0.0.0, I run into this infinite loop, the structure for the loop is the same as the other two, which have no problems. In this program, for a class C domain IP address to match the first 3 numbers of the IP Address need to match user input other wise continue onto the rest of the table. The specific issue that is happening is when it finds a match for the first number and continues to try and match the second number, and then for the third number. If the second number or third number doesn't match it jumps back to the loop, but then gets trapped there, which shouldn't be happening. At least, from what I can tell it shouldn't be.

The matching works beautifully, it is if it doesn't match that there is a problem, but again I am not sure why I am hoping that a fresh set of eyes will be able to help me see the issue. Also, sorry for any sloppiness in the code, and for it being kind of lengthy, it is rather simple though. I appreciate the help.

I'm a python student (by myself), and as an exercise I decided to try making a script to 'encrypt/decrypt' a message. The 'encryption algo' that I'm using is very simple, I learned during military service and it was used for troops in the field to encrypt radio messages only. I assume it's not a secure way to encrypt stuff. (If someone can comment on that, I would love to know more) Anyway, I'm doing it as an exercise for programming logic, but I've been stuck for a while now.

Here it's how it works:

You get a keyword/phrase (More often used with 2 words (vertical and horizontal) but for now I'm coding the 1 keyword only). Let's use 'PASSWORD' as key and the message: 'This is a sample message'. I would make a table with PASSWORD as colum index, and fill the table with the message:

I am debugging my program using gdb, fgets(line, sizeof(line), fp2) reads nothing from a text file. so the program loops infinity ins side while(!feof(fp2)) and the EOF is never met i dont know why?

I'm putting part of the code for context,

here is the inputfile:

I need to tokenize a string from an array, i need just three words and ignore all tabs '\t' and spaces ' '

the array line[] is just a test case.

I debugged mine, the first array (supposed to carry only the first word) got filled by spaces & letters from 3 words, not stopping after the first word when a tab or space is met. BTW my program crashed. i suspect getting out of array bounds maybe.

What am I doing wrong?

I'm writing the first pass of an assembler in C for an assignment and need to read in lines of a text file with assembly code, and store the label, opcode, and operand, as well as any comments in the line after the first three strings. I initially used

fscanf(fileptr1,"%s\t%s\t%s",label,opcode,operand);

for a file without comments, but sscanf wouldn't work to put the rest of the line into a single char array. It seems like I would use fgets, but how would I separate that into the first three strings separated by whitespace, followed by the rest of the line until the newline character?

For reference, the lines follow this formatting:

Im trying to make SIC assembler in c, made a small test program to search for "START" keyword and get the starting address from the assembly code file. then write them in another file as first pass. code didn't work. mind telling whats wrong with it?
