Problem $2.$ Using the srand$($time$($NULL$))$ and rand$(),$ fill an one dimentional array of size at least $100$ with random numbers that have been scaled to the range $1$ to $100$ and then display the array.

Find the average value in the array by defining a function findAveg$()$ that returns double type of average value and passing it to the second funtion standardDeviation$()$ function. The second function should return double type of standard deviation value.

The third function displays the return values from those two functions in the console. Use three functions at least in your solution.

double findAvg$($int $[],$ int$)$; $//$ function prototype

double stdDev$($int $[],$ int, double$)$; $//$ function prototype

void writeOut$($double$,$double$)$; $//$ function prototype
