Please help me with this:
Declare an integer array named "scores" to contain 50 elements.
&
Generate a code (a loop) that will initialize every element in the array from the above declaration("scores") to the value 75.

I hope this is not homework! That would be cheating!
This will do something like that, learn from it:
[php]
#include <iostream>
#include <iomanip> // for setw()
#include <stdlib.h> // for system()

using namespace std;

int main()
{
int k;
int scores[50]; // array to hold 50 integers

// initialize the array
for(k = 0; k < 50; k++)
scores[k] = 75;

// test it
for(k = 0; k < 50; k++)
cout << scores[k] << setw(8);

cout << endl;

system("PAUSE"); // wait
return 0;
}
[/php]

of course it's homework.
If it were not it wouldn't be worded as "do this, do that" which is most likely an exact replication of the text of his assignment...
