pow() isn't defined [closed]

Answer 1

I just ran the same program on my Turbo C and i got output as 341. Check whether your header files are in place in /include folder of your Turbo C folder. Make sure to check whether it contains a Math.h file.

Answer 2

Math library is not part of libc. You need to link it:

gcc file.c -lm -o file

Answer 3

This is a linker failure. You need to link with the math library, specify -lm at the end of your compiler command. From man pow:

Link with -lm.

Answer 4

The function pow() is defined in the math library. Your compiler by default is not linking your program with that library as a result of which the linker is unable the resolve the call to pow().

To fix this you need to add -lm at the end of your compile/link line which links the math lib to your program.
