C vs. Groovy

A quick program in C and Groovy, You can compare and contrast

/***Cost.groovy***/

//Calculate Cost
def cost (s,r,m) {
  s+(r*m)
}

//main portion of progam
(1..10).each{
   println "cost for month $it is ${cost(100,10,it) }"
}

---

/***Cost.c ***/

#include 

/* Function protoypes */
float cost(float,float,float);/*Calulates Costs */

/* main function */
void main (void) {
 float c=0; 
 int n;
 for (n=1; n<11; n++) {

  c=cost(100,10,n);
  printf ("Cost for month %i is %f\n",n,c);
 }

}



/* Cost Formula */
float  cost(float s, float r, float m) {
  return  (s+(r*m) );
}
