Questions tagged [imperative-programming]

Imperative programming is a paradigm of expressing the logic of a computer program or computation by explicitly describing its control flow in terms of statements that change a program state.

From Wikipedia:

In computer science, imperative programming is a programming paradigm that describes computation in terms of statements that change a program state. In much the same way that imperative mood in natural languages expresses commands to take action, imperative programs define sequences of commands for the computer to perform.

Why is functional-styled code so much faster than imperative code in C?

I've been working on an algorithm for calculating maximum depth of an expression (i.e. how many nested parentheses there are) in various languages just for fun/practice. I noticed there's a huge performance discrepancy in the performance of the…
