C program.....?

Write two versions of a program that displays the follwing table:





X X cubed


------------- -----------





Have the table continue until X is 20.





a. For the first version, write a function to do the cube calculation that takes


a single parameter. If the parameter is 2 on entry to the function, the parameter


should have the value 8 on exit from the function. That is, implement a


"pass by reference" on the function's parameter and have the cubed value


passed back in the parameter.





b. For the second version, write a function that does the cubing, but, have


the cubed value passed back to the main program as the return balue of the function.

C program.....?
Well your table looks a little messed up, but I can help you with the functions.





a would look like this...





void cubebyref(int %26amp;x)


{


x=x*x*x;


}





b would look like





int cubebyreturn(int x)


{


return x*x*x;


}





Hope that helps.
