These expressions use several shapes, including the geometric ones, to show the step-by-step process with arrows while establishing a data flow. A concurrency symbol with a single entry flow is a fork one with a single exit flow is a join.Īll processes should flow from top to bottom and left to right.A flowchart is a graphical representation of various logical steps of a program. The exit flows are activated concurrently when all of the entry flows have reached the concurrency symbol. It is normally represented by a double transverse line with any number of entry and exit arrows.They can be used whenever two or more control flows must operate simultaneously. In this case, a junction in control flow is implied. For each label, the “outflow” connector must always be unique, but there may be any number of “inflow” connectors. Normally used in complex or multi-sheet diagrams to substitute for arrows. They are represented by an identifying label inside a circle. A junction symbol will have more than one arrow coming into it, but only one going out. It is generally represented with a black blob, showing where multiple control flows converge in a single exit flow. It has two arrows coming out of it, usually from the bottom point and right point, one corresponding to Yes or True, and one corresponding to No or False. They commonly test a Yes/No question or True/False condition. These are normally represented as a diamond (rhombus) showing where a decision is necessary. They normally show operations which have no effect other than preparing a value for a subsequent conditional or decision step (see below). These are represented as a parallelogram. They are used to show complex processing steps which may be detailed in a separate flowchart. Subroutines are represented as rectangles with double-struck vertical edges. The meaning of the arrow with dashed line may differ from one flowchart to another and can be defined in the legend. The line for the arrow can be solid or dashed. For example an arrow coming from one symbol and ending at another symbol represents that control passes to the symbol the arrow points to. They contain the word “Start” or “End”, or another phrase signaling the start or end of a process, such as “submit inquiry” or “receive product”. They are represented as circles, ovals or rounded (fillet) rectangles. It is commonly used in textbooks and scientific publications that are documenting various algorithms, and also in planning of computer program development, for sketching out the structure of the program before the actual coding takes place.
#HOW TO MAKE A COMPUTER PROGRAM THAT FOLLOWS A FLOWCHART CODE#
The purpose of using pseudo code is that it is easier for people to understand than conventional programming language code, and that it is an efficient and environment-independent description of the key principles of an algorithm. The programming language is augmented with natural language description details, where convenient, or with compact mathematical notation. It typically omits details that are not essential for human understanding of the algorithm, such as variable declarations, system-specific code and some subroutines. Pseudo code uses the structural conventions of a programming language, but is intended for human reading rather than machine reading. It is a procedure for solving a problem in terms of the actions to be executed and the order in which those actions are to be executed. Pseudo code is an informal high-level description of the operating principle of a computer program or other algorithm.
