These are the guidelines for flow on control in the program. each void function only called one time in program execution. Need help with correcting the code to run and the general code I working with is at the bottom. Seriously need help to get this code running. Thank you for any help you can provide.
-----------------------------------------------------------------------------
Declarations in global or in void functions or main--} only where necessary.
1.void getScore(); ///Ask user for score and store in reference parameters - Main can only be called once for each set of 5 scores to entered once.

2.void findLowest( int testScore[], int sz );/// - Main only called once-pass all 5values to calcAverage function to determine the lowest score to drop from execution.

3.void calcAverage ( );--Calculate and display average of the highest for 4 scores and drop lowest score value. Return flow to main and main ends program
-------------------------------------------------------------
int main() -- main ends flow of control.
{
1, 2, 3, end
}

The code i AM WORKING WITH below:

float lowest = testScore[0]; // make the first element of the array the lowest.
// loop through the array and compare the rest with

}

cout << "The lowest is " << lowest << endl;

}
void calcAverage()
{

for ( float i = 0.0; sz < i; i++ )

if ( i > lowest )
