Write a program to read two num and evaluate and display their sum using a function

   1:  #include<stdio.h>

   2:  #include<conio.h>

   3:  float getsum(float a,float b);

   4:  void main()

   5:  {

   6:  float x,y;

   7:  float sumxy;

   8:  printf("Enter the two num:\n");

   9:  scanf("%f%f",&x,&y);

  10:  sumxy=getsum(x,y);

  11:  printf("The sum of %f and %f is: %f",x,y,sumxy);

  12:  getch();

  13:  }

  14:  float getsum(float a,float b)

  15:  {

  16:  float sum;

  17:  sum=a+b;

  18:  return(sum);

  19:  }
