[c언어] 표준편차 구하기

세 개의 실수를 입력받은 후 표준편차를 계산하는 프로그램 #include #include double average(double a, double b, double c) { return (a + b + c) / 3.0; } double std_deviation(double a, double b, double c) { double avg, var; avg = average(a, b, c); var = ((a - avg)*(a - avg) + (b - avg)*(b - avg) + (c - avg)*(c - avg)) / 3; return(sqrt(var)); } int main(){ double a, b, c; printf("Enter three real numbers.\n"); scanf("%lf%lf%lf", &a, &b, &c); printf("Standared deviation is %lf.

\n", std_deviation(a, b, c)); ...
