got problem with array and function
 
i got some problem to answer this question..
please help me!!
hope u all can help me..

Consider the following function main:
Int main()
{
int inStock[10][4];
int alpha [20];
int beta[20];
int gamma[4]= {11,13,15,17};
int delta [10] = {3,5,2,6,10,9,7,11,1,8};
}
a) Write the definition of the function setZero that initializes any one-dimentional array of type int to 0.
b) Write the definition of the function inputArray that prompts the user to input 20 numbers and stores the numbers into alpha.
c) Write the definition of the function doubleArray that initializes the elements of beta to two times the corresponding elements of alpha. Make sure that you prevent the function from modifying the elements of alpha.
d) Write the definition of the function copyGamma that sets the elements of the first row of inStock to gamma and the remaining rows of inStock to three times the previous row of inStock. Make sure that you prevent the function from modifying the elements of gamma.
e) Write the definitions of the function copyAlphaBeta that stores alpha into the first five rows of inStock and beta into the last five rows of inStock. Make sure that you prevent the function from modifying the elements of alpha and beta.
f) Write the definition of the function printArray that prints any one-dimensional array of type int. print 15 elements per line.
g) Write the definition of the function setInStock that prompts the user to input the elements for the first column of inStock. The function should then set the elements in the remaining columns to two times the corresponding elements in the previous column, minus the corresponding element in delta.
h) Write C++ statements that call each of the functions in parts a through g. :confused:

Re: got problem with array and function
 
Well, we're not going to do your homework for you, but we don't mind helping. Let's take the first one:

a) Write the definition of the function setZero that initializes any one-dimentional array of type int to 0.

OK, seems easy enough. Do you know how to write a function definition? What parameters do you think this function needs to take? What types are they? How do you think you might code the function body?

If it helps, think of it as a task you're going to give someone to do. An array would be represented by a sheet of paper with a load of squares on it. How would you get someone to fill the squares with zeroes? Imagine that person is REALLY REALLY thick and needs stuff explaining in microscopic detail.
