Memory representation
❖ Jenny's Lectures CS IT
❖ , we'll discuss how data is represented in memory, and the need for arrays. Faerie
explains the need for arrays as we often have to process large amounts of data, and
arrays allow us to store multiple values under one variable name
❖ . We'll cover how arrays can be declared and how data can be stored in memory. The
declaration of arrays is language-specific, and in this video, we'll consider the syntax in
the C language.
❖ The elements of the array are stored in consecutive or continuous locations, with their
index starting from zero. The size of the array cannot be changed at runtime. We'll
discuss how data is stored in memory, with the binary form of the data being converted
and then stored.
❖ The formula to calculate the address of an element is the base address plus the index
value multiplied by the size of the data type.
❖ We'll cover how to initialize the array at runtime using loops or predefined functions, and
how to take data from the user and store it in an array
