My solutions to the advent of code 2020

My solutions to the 2 daily exercises in both C and Bash (also Cobol for day 1, I may try some other languages).

My own rules:

• C : Only standard libraries (for example, no external sort).
• bash: Pure bash only: No external commands allowed (grep, sed, etc...).

Done:

• Day 1: Bash, C, and Cobol
• Days 2-18: Bash and C
• Days 19-20: Bash
