Question

Write a C++ program that reads a set of floating-point data values. Use a sentinel-controlled while loop to end entering data values. When all values have been read, print out the count of the values, the average, and the standard deviation. Use the following formula for calculating standard deviation.

Explanation / Answer

#include #include using namespace std; int main(){ char wait; float sumx=0,sumxx=0,input,S,s,avg; int n=0; coutinput; while(input!=-999999){ n++; sumx+=input; sumxx+=pow(input,2); cin>>input; } avg=sumx/n; S=sqrt(((n*sumxx)-(pow(sumx,2)))/(n*(n-1))); //think that this formula is wrong ..., but is according to your formula :/ //should be this? s=sqrt(((sumxx/n)-(pow(avg,2)))); cout
