Source Code - Programs
In computer science, source code is any collection of statements or declarations written in some human-readable computer programming language. Source code is the means most often used by programmers to specify the actions to be performed by a computer. Source code can also be a working program.C++ Program: While loop counter
Compiler (Visual Studio) showing C++ Source Code:
// While loop.
#include <iostream>
using namespace std;
int main()
{
int num = 1; // Initialize counter starting at 1.
while (num <= 7) // Loop - number controls how many times.
{
cout << num; // Show the number as it increments.
num++; // Increment by adding 1 each iteration.
cout << " - Hello world!\n";
}
cout << "\n";
return 0;
}
/*==================[output]===============================
1 - Hello world!
2 - Hello world!
3 - Hello world!
4 - Hello world!
5 - Hello world!
6 - Hello world!
7 - Hello world!
Press any key to continue . . .

The above source code is C++, using a while loop.Here is the Source Code: while loop
Debugging Source Code
Debugging is a very important task in the software development process, because an incorrect program can have significant consequences for its users. Some languages are more prone to some kinds of faults because their specification does not require compilers to perform as much checking as other languages. Use of a static analysis tool can help detect some possible problems. Debugging is often done with IDEs like Visual Studio (Microsoft), NetBeans, and Eclipse. Standalone debuggers like GDB are also used, and these often provide less of a visual environment, usually using a command line.Computer Programming
Computer programming (often shortened to programming or coding) is the process of writing, testing, debugging/troubleshooting, and maintaining the source code of computer programs. This source code is written in a programming language. The code may be a modification of an existing source or something completely new. The purpose of programming is to create a program that exhibits a certain desired behavior (customization). The process of writing source code often requires expertise in many different subjects, including knowledge of the application domain, specialized algorithms and formal logic.
Source Code style and visual appearance
The issues usually considered as part of programming style include the layout of the source code, including indentation, the use of white space around operators and keywords, the style and spelling of user-defined identifiers, variable names, and the use of comments.Source code quality
Coding style:A computer has no concept of "well-written" source code. However, from a human point of view source code can be written in a way that has an effect on the effort needed to comprehend its behavior. Many source code programming style guides, which often stress readability and usually language-specific conventions are aimed at reducing the cost of source code maintenance.
Understandability
Are variable names descriptive of the physical or functional property represented? Do uniquely recognizable functions contain adequate comments so that their purpose is clear? Are deviations from forward logical flow adequately commented? Are all elements of an array functionally related?Source Code VS. ambiguous?
Thousands of different programming languages have been created, mainly in the computing field. Programming languages differ from most other forms of human expression in that they require a greater degree of precision and completeness. When using a natural language to communicate with other people, human authors and speakers can be ambiguous and make small errors, and still expect their intent to be understood. However, figuratively speaking, computers "do exactly what they are told to do", and cannot "understand" what code the programmer intended to write. The combination of the language definition, a program, and the program's inputs must fully specify the external behavior that occurs when the program is executed, within the domain of control of that program.Which language is most widely used?
Combining and averaging information from various Internet sites, langpop.com claims that in 2008 the 10 most cited programming languages are (alphabetical order): C, C++, C#, Java, JavaScript, Perl, PHP, Python, Ruby, and SQL.Source Code

Before 1940
The first programming languages predate the modern computer. At first, the languages were codes. The Jacquard loom, invented in 1801, used holes in punched cards to represent sewing loom arm movements in order to generate decorative patterns automatically. During a nine-month period in 1842-1843, Ada Lovelace translated the memoir of Italian mathematician Luigi Menabrea about Charles Babbage's newest proposed machine, the Analytical Engine. With the article, she appended a set of notes which specified in complete detail a method for calculating Bernoulli numbers with the Engine, recognized by some historians as the world's first computer program.Programming Languages by year
