Calculate Standard Deviation In C++ Programs

Write C++ Program to Calculate Standard Deviation.

Source Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

#include <iostream> #include <cmath> using namespace std; float calculateSD(float data[]); int main() { int i; float data[10]; cout << "Enter 10 elements: "; for(i = 0; i < 10; ++i) cin >> data[i]; cout << endl << "Standard Deviation = " << calculateSD(data); return 0; } float calculateSD(float data[]) { float sum = 0.0, mean, standardDeviation = 0.0; int i; for(i = 0; i < 10; ++i) { sum += data[i]; } mean = sum/10; for(i = 0; i < 10; ++i) standardDeviation += pow(data[i] - mean, 2); return sqrt(standardDeviation / 10); }

Enter 10 elements: 1
