Subroutines could be implemented, but they required programmers to use the call sequence—a series of instructions—at each call site. Subroutines were implemented in Konrad Zuse's Z4 in 1945. In 1945, Alan M. Turing used the terms "bury" and "unbury" as a means of calling and returning from subroutines. [9] [10]
In computer programming, a nested function (or nested procedure or subroutine) is a named function that is defined within another, enclosing, block and is lexically scoped within the enclosing block – meaning it is only callable by name within the body of the enclosing block and can use identifiers declared in outer blocks, including outer ...
In computer programming, a return statement causes execution to leave the current subroutine and resume at the point in the code immediately after the instruction which called the subroutine, known as its return address. The return address is saved by the calling routine, today usually on the process's call stack or in a register.
Procedural programming is a type of imperative programming in which the program is built from one or more procedures (also termed subroutines or functions). The terms are often used as synonyms, but the use of procedures has a dramatic effect on how imperative programs appear and how they are constructed.
Procedural programming is a programming paradigm, classified as imperative programming, [1] that involves implementing the behavior of a computer program as procedures (a.k.a. functions, subroutines) that call each other. The resulting program is a series of steps that forms a hierarchy of calls to its constituent procedures.
Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making specific disciplined use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines.
In computer science, threaded code is a programming technique where the code has a form that essentially consists entirely of calls to subroutines.It is often used in compilers, which may generate code in that form or be implemented in that form themselves.
A wrapper function is a function (another word for a subroutine) in a software library or a computer program whose main purpose is to call a second subroutine [1] or a system call with little or no additional computation. Wrapper functions simplify writing computer programs by abstracting the details of a subroutine's implementation.
