The C Language in a nutshell...

Intro...

C is a general-purpose, high-level programming language that was first developed in the early 1970s. It is considered to be one of the most widely used and versatile programming languages in the world. Here are some of the basics of the C programming language:

Syntax

C has a simple and straightforward syntax that is easy to learn and understand. It uses a combination of keywords, variables, and operators to create statements that are executed by the computer.

Data Types

C supports a variety of data types including integers, floating-point numbers, characters, and strings.

Variables

Variables are used to store data in C. They are declared with a specific data type and can be used to store values, expressions, or even the results of calculations.

Operators

C supports a variety of operators such as mathematical operators (e.g. +, -, *, /), comparison operators (e.g. ==, !=, >, <), and logical operators (e.g. &&, ||, !).

Control Flow

C uses control flow statements such as if, else, for, while, and do-while loops to control the flow of execution in a program.

Functions

Functions are used to divide a program into smaller, more manageable pieces. Functions can be defined and called by the main program or by other functions.

Pointers

C uses pointers to manipulate memory directly, they are variables that store the memory addresses of other variables.

Input/Output

C uses a variety of functions such as scanf() and printf() to handle input and output operations.

Libraries

C has a large number of standard libraries that provide a wide range of functions for tasks such as mathematical calculations, string manipulation, and input/output operations.

Compilation

Programs written in C need to be compiled before they can be executed by the computer. The process of compilation converts the source code into machine-readable code.

AI agents

AI agents struggle with latency and context switching. Redis fixes it with a fast, in-memory layer for short-term context—plus native support for vectors and semi-structured data to keep real-time workflows on track.

🐯 🚀 Timescale is now TigerData: Building the Modern PostgreSQL for the Analytical and Agentic Era

We’ve quietly evolved from a time-series database into the modern PostgreSQL for today’s and tomorrow’s computing, built for performance, scale, and the agentic future.

So we’re changing our name: from Timescale to TigerData. Not to change who we are, but to reflect who we’ve become. TigerData is bold, fast, and built to power the next era of software.
