;How Does sizeof() Operator Work in C? sizeof() operator is a flexible and versatile operator for computation of the bytes and the memory for ingesting the required values and return those values after computation. It is not at all compiler-specific and thus varies from compiler to compiler. ;datatype size = sizeof(array_name) / sizeof(array_name[index]); Let's break it down: size is the variable name that stores the size of the array, and datatype specifies the type of data value stored in size. sizeof(array_name) calculates the size of the array in bytes. sizeof(array_name[index]) calculates the size of one element in the array.
