main.c:16:9: error: stray '\32' in program in C [closed]

I am trying an example from the GNU C Programming Tutorial (page 93) that uses a few of the math library routines listed.

#include <stdio.h>#include <math.h>int main() {  double my_pi;  my_pi = 4 * atan(1.0);  /* Print the value of pi, to 32 digits */  printf("my_pi = %.32f\n", my_pi);  /* Print value of pi from math library, to 32 digits */  printf("M_PI = %.32f\n", M_PI);  return 0;}

When I compile the file 'main.c' using MinGw using the command

gcc main.c -o main -lm

It gives the following error:

main.c:16:9: error: stray '\32' in program    16 :      }      :       ^
