The C programming language has spurred many language developments since its invention by Dennis Ritchie in the early 1970s. Many modern programming languages owe their syntax to C: learning C first makes learning other languages such as Java, php, and Swift much easier. C is still a very popular programming language after over 40 years
SQL Structured Query Language is a special-purpose programming language designed for managing data held in a relational database management system (RDBMS). SQL is used to retrieve data from different tables in databases, and then combine it together to create reports. It has a pretty simple syntax, and, in my experience almost anyone can start using SQL to create reports within a few minutes.
