Some of the special symbols that are used in C programming are as follows − [] () {}, ; * = # Let’s understand their definitions, which are as follows − Brackets[] − Opening and closing of brackets are used for array element reference, which indicate single and multidimensional subscripts. Parentheses() − These special symbols are used for function calls and function parameters. Braces{} − Opening and closing of curly braces indicates the start and end of a block of code which cont

uint is a keyword that is used to declare a variable which can store an integral type of value (unsigned integer) from the range of 0 to 4,294,967,295. uint keyword occupies 4 bytes (32 bits) space in the memory C specifies the exact minimum storage size for each integer form. For example, short requires at least two bytes, and long requires at least four bytes. The compiler determines the size and range of a data type As a result, we should not hardcode the size and range values in the progr
