Braces (curly brackets) first became part of a character set with the 8-bit code of the IBM 7030 Stretch. [ 7 ] In 1961, ASCII contained parentheses, square, and curly brackets, and also less-than and greater-than signs that could be used as angle brackets.
Braces { } are used to identify the elements of a set. For example, {a,b,c} denotes a set of three elements a, b and c. Angle brackets are used in group theory and commutative algebra to specify group presentations, and to denote the subgroup or ideal generated by a collection of elements.

A curly bracket or curly brace language has syntax that defines a block as the statements between curly brackets, a.k.a. braces, {}. This syntax originated with BCPL (1966), and was popularized by C. Many curly bracket languages descend from or are strongly influenced by C. Examples:
Brace (sailing), the lines used to rotate the yards around the mast; Braces (punctuation), the "{" and "}" symbols, i.e., "curly brackets" Curly bracket programming language, a programming language that uses braces; Bracing style, a type of indent style used in computer programming "Braces" (Care Bears episode), an episode of Care Bears

The term curly bracket programming language denotes a language that shares C's block syntax. [1] [2] C-family languages have features like: Code block delimited by curly braces ({}), a.k.a. braces, a.k.a. curly brackets; Semicolon (;) statement terminator; Parameter list delimited by parentheses (()) Infix notation for arithmetical and logical ...
Parentheses can be nested, and should be evaluated from the inside outward. For legibility, outer parentheses can be made larger than inner parentheses. Alternately, other grouping symbols, such as curly braces { } or square brackets [ ], are sometimes used along with parentheses ( ). For example:
