I am running into a problem with the pow function in my program. The function is part of a for loop and here is the code section:

for( year = 1; year <= 10; ++year)
{
amount = principal * pow( 1.0 + rate, year);
printf( "%4u%21.2f\n", year, amount);
}

When I run my program I get the following error message:

/tmp/cc9xIlqs.o: In function 'main':
main.c: (.text+0x84): undefined reference to 'pow'
collect2: error: ld returned 1 exit status

Can anyone provide help with this?
