Functional Programming in CLEAN

Computer programs, too, are descriptions of the way a result can be computed, given some arguments. A natural way to write a computer program is therefore t ...

Introduction to Imperative C Functional vs. imperative programming
... An expression with a side effect does more than produce a value: it also changes the state of the program (or “the world”). Functions (or programs) can also have side effects. We have already seen a C function with a side effect: printf. The side effect of printf is that it displays “output”. In oth ...

Functional Programming Paradigm Learning Outcomes:

Functional Images

This paper presents the types and operations that make up Pan, and illustrates their use through a collection of examples. Some of the exa ...

C Programming conditional Statements

Then, the test expression in the for loop,i.e., (count<= n) becomes true. So, the code in the body of for loop is executed which makes sum to 1. Then, the expression ++count i ...
