Historically, explicit looping constructs emerged early in high-level languages. The Fortran DO loop is a classic
Common forms of a do loop appear across languages. In Fortran, a fixed-count loop takes the shape
Typical uses include iterating over ranges or arrays, performing repeated calculations, or applying an operation to
Common pitfalls include off-by-one errors, infinite loops if the termination condition never becomes true, and modifying
