A

Coding

70
Q

In this phase we determine the problem, need, and output of the problem. Afterward, we identify the requirements needed to solve the problem, such as variables, data input from the user, and the limitations of the program.

A

Problem Definition and Analysis

71
Q

After determining the problem and its requirements, we then developed the

A

Algorithm Development

72
Q

After developing the program’s algorithm, we proceed to the actual ___ of the program.

A

Coding

73
Q

We use ___ to “communicate” with the computer.

A

Programming language

74
Q

Examples of programming languages

A

Phyton
C++
C#

75
Q

Phyton was created in 1991 by

A

Guido van Rossum

76
Q

It is use for web and software development, and web-based applications.

A

Phyton

77
Q

Now that the code has been written out, we test if the code works and displays the correct output. If it does the code is correct; otherwise, we take a look at the codes again and checked for errors.

A

Testing and Debugging

78
Q

This phase involves users actively using the program. In this phase we can still check for improvements, enhancements, or new problems in the program; thereby repeating the same cycle again.

A

Maintenance

79
Q

A

Sequential structure

80
Q

Some instructions may involve decisions or conditions before they are executed; otherwise, another set of instructions is executed.

A

Conditional (decision-making) structure

81
Q

A certain set of instructions is repeated or roped in a certain number of times.

A

Iterative (looping) structure
