Global variables: Global variables are variables that are defined at the beginning of the program and can be accessed through the execution of the entire program. The Global variable is usually defined as a static variable. Local variables: Local variables are variables that can only be accessed within the certain section of the code like a function or method and not available during the complete execution of the program. In certain cases if the local variable is redeemed with the same name as a global variable then the local variable will take precedence in the corresponding scope. Parameter passing: Parameter passing is a technique, which allows variable’s value to be passed through the program and is then used for further processing within a function. Modularity: Modularity is a technique that allows…show more content…
Iverson. Its central data type is the multi-dimensional array. Advantages: APL is a communicating language returning answers. APL is very easy to learn and use; if you make a mistake, it is easy to fix. APL code takes very less time to write and debug than any other high level language.It is most efficient and cost effective language from the shared personnel and hardware point of view. Disadvantages: It is an interpretive language, which means it will compute slower than a compiled or assembled language It is difficult to maintain significant programs with potentially thousands of lines of code Key features: Conceptualised as a hardware description language at IBM Very expressive with support for many operators, for both scalars and arrays having various dimensions Programs can be difficult to understand and read Language is still in use but with minimal changes SIMULA
