The most common reason for errors like "undefined reference to sqrt " is that the math library (often called libm ) is separate from the standard C library. While the header file tells the compiler what to expect, the linker needs to find the actual precompiled code. How to compile a C program that uses math.h? - Ask Ubuntu

Instead of searching for a download, you must ensure two things are in place to use math functions: 1. Include the Header At the very top of your .c file, add this line: #include Use code with caution.

If you are seeing errors when using math functions, it is rarely because the file is missing; rather, it's usually because the library isn't being correctly or your compiler isn't installed properly. Why You Don't Need to Download math.h

This tells the compiler what the functions look like (their prototypes) so it knows how to call them. 2. Link the Library (The "Hidden" Step)

It is included with Visual Studio (MSVC) or MinGW/MSYS2. How to Properly "Get" the Math Library

It is part of the GNU C Library (glibc) or equivalent, usually located in /usr/include/math.h .
