Procedural Programming  vs Functional Programming Learn Java  Procedural programming focuses on a step-by-step sequence of instructions that change data over time, while functional programming treats computation as the evaluation of mathematical functions without changing state. Core Differences Execution Style : Procedural programming is imperative; you tell the computer how to do something by listing actions in order. Functional programming is declarative; you describe what result you want by combining functions. State and Data : Procedural code uses variables that update and can be shared globally or modified by different procedures. Functional code relies on immutability, meaning data cannot change once created, and avoids shared state.    Side Effects : Procedural functions often cause side effects by altering external variables or system states. Functional programming uses pure functions —functions that always return the same output for the same input and cau...

What is imperative and declarative programming Learn Java   Imperative programming is a programming style where you tell the computer exactly what steps to perform, and in what order . Think of it like giving someone a recipe: Get some flour. Add water. Mix them. Bake the mixture. In programming, you might write: x = 5 y = 10 sum = x + y print(sum) The program executes these instructions sequentially: Store 5 in x Store 10 in y Add x and y Store the result in sum Print sum Key characteristics Imperative programs commonly use: Variables — store changing data Assignment — change the value of variables Loops — repeat instructions Conditionals — choose which instructions to execute Functions/procedures — group instructions together Statements — individual commands that change the program's state For example: total = 0 for i in range(1, 6): total = total + i print(total) Here, total changes state as the program runs: 0 → 1 → 3 → 6 → 10 → 15 ....
