Thread: Hypotenuse Problem

I am working on a problem for class and I am getting a
[Linker error] undefined reference to `hypotenuse(double, double)' message. Can someone explain why this is happening. Here is my code:

Code:

#include <stdio.h>
#include <math.h>

/* Function Prototype */
double hypotenuse( double sidea, double sideb );

/* Function main begins program execution */ 
int main() 
{
    double sidea; /* Variable in which sidea will be stored */
    double sideb; /* Variable in which sideb will be stored */
    
    printf( "Enter the length of side a: \n" ); /* Prompt for input */
        scanf( "%lf", &sidea); /* Read number from user */ 
    printf( "Enter the length of side b: \n\n" ); /* Prompt for input */
        scanf( "%lf", &sideb); /* Read number from user */
    printf( "The length of side c is %lf", hypotenuse( sidea, sideb ) ); /* Display results */
                   
  return 0; /* Indicates that program ended successfully */ 
 
} /* End function main */

double hypontenuse( double sidea, double sideb )
{

    return sqrt( pow( sidea, 2) + pow( sideb, 2) );
    
} /* End function main */

Thanks in advance

Thank you - I feel silly for missing that. I guess that is what happens when you stare for to long

Thanks again
