CEG221: Advanced C Programming for Engineers

Requirements for a Program Specification

1) You must outline in English what the goal of your program does

2) Break down steps into functions – specify inputs and outputs

3) Outline anything more specific in pseudocode.

Example: Computing the Standard Deviation of an array of floating point numbers

· We will need a #define value SIZE which is the size of the array

· We will need a function to ask the user for each element in the array

{

float array[SIZE] = {0};

// begin function POPULATE

for each element in array

{

ask the user for a value

add that value to the ith position of the array

}

// end function POPULATE

avg = average(array); // need to write this function

double variance = 0;

for each element in array

{

variance += square(ith element – avg);

}

output standard deviation = sqrt(variance);

return 0;

}
