Origin of 'pointers'

Main points about word origin

  • The term originates from the word 'point', which means to indicate or direct attention.
  • In the late 18th century, it was used to describe anything that helps to guide someone or something.
  • The use of 'pointer' has evolved to include both physical objects and digital forms.

The term 'pointer' originated in the late 17th century from the verb 'point,' which means to direct someone's gaze or attention toward something specific. Over time, it evolved to represent objects or signs that indicate or guide towards something. In the realm of computer programming, the concept of pointers emerged in the mid-20th century with the development of languages like C, where they became essential tools for manipulating memory and enhancing performance.
