\`sizeof\` is an operator in several programming languages, including C, C++, and others, that returns the size (in bytes) of a data type or object. It can be used to determine how much memory a variable occupies. The \`sizeof\` operator can be applied to primitive data types, such as \`int\`, \`char\`, \`float\`, or to user-defined types, such as structs, classes, and arrays.
