C - SIMPLE  PROGRAMS



6: C Language Program which takes three numbers as input from the user and Calculate the first four Moments about mean. Also print the results.

#include<stdio.h>
#include<conio.h>
#include<math.h>
main( )
{
int n;
float x,y,z,m1,m2,m3,m4,mm1,mm2,mm3,mm4;
printf("Enter the value of x , y and z : ");
scanf("%f,%f,%f”,&x,&y,&z);
m1=(x+y+z)/3;
m2=(pow(x,2)+pow(y,2)+pow(z,2))/3;
m3=(pow(x,3)+pow(y,3)+pow(z,3))/3;
m4=(pow(x,4)+pow(y,4)+pow(z,4))/3;
mm1=m1-m1;
mm2=m2-pow(m1,2);
mm3=m3-3*m1*m2+2*pow(m1,3);
mm4=m4-4*m3*m1+6*m2*pow(m1,2)-3*pow(m1,4);
printf("\nm1=%f",m1);
printf("\nm2=%f",m2);
printf("\nm2=%f",m3);
printf("\nm2=%f",m4);
printf("\nmm1=%f",mm1);
printf("\nmm2=%f",mm2);
printf("\nmm3=%f",mm3);
printf("\nmm4=%f",mm4);
getch( );
