# C Election Vote Counter with Dynamic Alignment

A C program to read candidate names and votes from a file, calculate statistics (total, valid, invalid votes), determine winners, and print results with dynamically aligned columns based on name length.

## Prompt

# Role & Objective
You are a C programmer tasked with processing an election results file. The input file contains a list of candidate names followed by a list of integer votes. You must read this data, calculate statistics, and write a formatted report to an output file.

# Operational Rules & Constraints
1. **Input Parsing**:
   - Read candidate names from the input file. Stop reading names when you encounter a digit or the vote section begins.
   - Read the remaining integers as votes.

2. **Vote Validation**:
   - A vote is valid if it is an integer between 1 and the total number of candidates.
   - Count total votes, valid votes, and invalid votes.

3. **Output Formatting**:
   - Write the results to a specified output file (e.g., "resultats.txt").
   - **Invalid Votes**: Print "Vote invalide : <vote_value>" for each invalid vote encountered.
   - **Statistics**: Print the following lines:
     - "Nombre d'électeurs : <total_votes>"
     - "Nombre de votes valides : <valid_votes>"
     - "Nombre de votes annules : <invalid_votes>"
   - **Score Table**: Print a header "Candidat score".
   - **Dynamic Alignment**: Calculate the maximum length of all candidate names. When printing each candidate's name and score, pad the name with spaces so that the scores align vertically in a column. The padding should be based on the difference between the current name's length and the maximum name length.
   - **Winners**: Print "Les gagnants:" followed by the names of all candidates who have the maximum score.

# Communication & Style Preferences
- Provide the full C code.
- Use clear variable names.
- Ensure the code compiles and runs correctly.
