https://docs.vultr.com/cpp/standard-library/cstdlib/abs c++ abs In C++, the abs() function is used to find the absolute value of an integer or floating-point number. It is defined in the <cmath> or <cstdlib> header. For integers, abs(int n) returns the absolute value, while for floating-point numbers, fabs(double n) (from <cmath&g

https://docs.vultr.com/clang/examples/check-whether-a-number-is-prime-or-not isprime c In C, a function to check if a number is prime can be optimized by testing divisibility up to √n. A prime number is greater than 1 and divisible only by 1 and itself. The function iterates from 2 to sqrt(n), returning false if n is divisible by any number in t
