what is source code

Source code is a text that describes the behavior of a program. Source code can exist in every software. The software executes according to the programming in the source code. Commonly used The format is a text file. The ultimate goal of computer source code is to translate human-readable text into binary instructions that the computer can execute. This process is called compilation, and is completed through a compiler.

For example, Java source code

final PropertyUtilsBean propUtils = (pu != null) ?
                          pu : PropertyUtilsBean.getInstance();
    final CacheKey key = new CacheKey(beanClass, propUtils);
    WrapDynaClass dynaClass = getClassesCache().get(key);
    if (dynaClass == null) {
        dynaClass = new WrapDynaClass(beanClass, propUtils);
        getClassesCache().put(key, dynaClass);
    }

Each line has a unique meaning. Each line is composed of a computer instruction. The computer instruction is read from top to bottom. Source code can be written in various programming languages. There are currently more than 200 programming languages, including Java, C language, PHP, Python and other source codes. Even for the same operation, the description method depends on the programming language. Therefore one needs to understand each language to read the source code.
