Introducing Computer Programming
Category : 6th Class
Computer programs are set of instructions that enable a computer to interact with the user, peripherals and information. These instructions are written in a language called computer programming language. The process of writing computer programs is called computer programming. While writing a program using a computer programming language, such as C, you need to follow the syntax of that language. A programming language also provides operators that enable you to perform various tasks, such as computing and manipulating values of variables, compare values of different variables of same data types and test multiple conditions.
Developing Flowchart
Flowchart is a technique that allows you to represent computer program graphically. Using flowchart you can easily understand the logic of a program. A flowchart represents the logical and operational steps to be performed within the system for transforming the input process into output. Flowchart serves as a basis for discussion and communication between the system analysts and the programmers.
To create a flowchart, you need to use the following symbols
SYMBOL | DESCRIPTION |
This symbol is used to represent the start and the end of an algorithm or process. | |
This symbol is used to represent the logic used in a process or algorithm. | |
This symbol is used to represent the input/output steps of a process. | |
This symbol is used to represent the conditional situation of a process. | |
This symbol is used to represent the flow of control in a process. |
While creating a flow chart you need to keep the following points in your mind
The following figure displays the flowchart of a program for printing grade of employ according to his or her salary: (See Figure 6.1.4)
Using flowchart you can grip logic of algorithm easily. Which one of the following symbol is used to represent conditional situation of a process in flowchart?
(E) None of these
Answer: (d)
Explanation
Correct Option:
(D) This symbol is used to represent the conditional situation of a process.
Incorrect Option:
(A) This symbol is used to represent the start and the end of an algorithm or process.
(B) This symbol is used to represent the logic used in a process.
(C) This symbol is used to represent the input/output steps of a process.

How many flow lines can enter in the end symbol of a flowchart?
(A) One
(B) Two
(C) Three
(D) None
(E) None of these
Answer: (a)
Explanation
Correct Option:
(A) Only a single flow line comes out from starting process and enters single flow line in stop process.
Incorrect Options:
Rest of the options is incorrect.
