A "C-shape" refers to a curved form that resembles the letter "C." This shape can be found in various contexts, such as in design, architecture, and nature. For example, the shape of a crescent moon or certain types of shells can be described as C-shaped. In mathematics, a C-shape can also represent a specific type of graph or curve. In statistics, it may illustrate trends or patterns, such as a C-shaped distribution, where data points cluster around two extremes with a gap in the middle.
