C++ Output Implementations // Are there ways to perform faster ?

Revision en24, by SPyofgame, 2020-03-08 14:31:46

Here are some implementations to output numbers I found

Time to write first 10.000.000 non-negative numbers (base on Codeforces Custom Test // GNU G++ 17 7.3.0)

Putchar Non-recursive Dividing Implementation: 3649ms
Putchar Recursive Implementation: 3510ms
Putchar Reverse Implementation: 3462ms
Putchar Non-recursive toString Implementation: 3369ms
Printf Implementation: 1762ms
synchronized(off) Implementation: 1356ms
synchronized(true) Implementation: 1060ms
Normal Cout Implementation: 1045ms
fwrite buffer Implementation: 545ms

Time to write 1.000 times first 10000 numbers (base on [Codeforces Custom Test](https://codeforces.me/problemset/customtest) // GNU G++ 17 7.3.0)

Putchar Reverse Implementation: 1981ms
Putchar Non-recursive Dividing Implementation: 1980ms
Putchar Non-recursive toString Implementation: 1934ms
Putchar Recursive Implementation: 1887ms
Printf Implementation: 1216ms
synchronized(on) Implementation: 873ms
Normal Cout Implementation: 873ms
synchronized(off) Implementation: 857ms
fwrite buffer Implementation: 311ms

Time to write first 10.000.000 non-positive numbers (base on Codeforces Custom Test // GNU G++ 17 7.3.0)

Putchar Non-recursive toString Implementation: 3946ms
Putchar Reverse Implementation: 3930ms
Putchar Recursive Implementation: 3915ms
Putchar Non-recursive Dividing Implementation: 3883ms
Printf Implementation: 1808ms
