CSV Console Table in C

This C implementation provides precise control over data validation and table formatting, ensuring column types match while creating clean, aligned console output - making it ideal for consistent data snapshots and type verification.

Example Input CSV (generic.csv):

1,"Welcome to csv-console-table-c",9.98,UNKOWN,1,true
2,"This is a sample data csv file",19.97,321654AE,2,false
3,"1st row: set header types",1.99,"null",3,true
4,"Detect headers: 'int *char float *char int bool'",11.99,NULL,4,true
5,"Unknown types become `*char/string`",19.97,OU812,5,true
6,"'gcc -o xyz .\csv_console_table.c'",19.17,"string",6,true
7,"'.\xyz .\yourfile.csv'",19.84,"*char",7,false
