write a program in java tto find the sum of given series
S= a/2! + a*a/3! +a*a*a/4! ............a*a*a*a*a*a*a*a*a*a/11!
where
factorial of 4 means : 4!=4*3*2*1

import java.io.*;
public class series
{
float S;
ISR ir=new ISR(System.in);
BR br=new BR(ir);
public void prog()throws IOException
{
System.out.println("Enter a number");
String s =br.readLine();
int a=Integer.parseInt(s);
while(a!=0)
{
for(int i=2;i<=11;i++)
{
for(int j=1;j<=10;j++)
{
S=S+Math.pow(a,j)/i;
}
}
}
System.out.println("The sum of the series is"+S);
}
}

just check out whether the output is right.

Active member

the output is not coming
1) variable S should be DOUBLE
Secondly we have to find the factorial of i and then divide it

import java.io.*;
public class Product
{
InputStreamReader isr=new InputStreamReader(System.in);
BufferedReader bf=new BufferedReader(isr);
public void main() throws IOException
{
int a[][]=new int[3][4];
int b[][]=new int[4][3];
int c[][]=new int[3][3];
for(int i=0;i<3;i++)
{
for(int j=0;J,4;j++)
{
a[i][j]=Integer.parseInt(bf.readLine());
}
}
for(int k=0;k<4;k++)
{
for(int l=0;l<3;l++)
{
b[k][l]=Integer.parseInt(bf.readLine());
}
}
for(int m=0;m<3;m++)
{
for(int n=0;n<3;n++)
{
c[m][n]=0;
for(int o=0;o<4;o++)
{
c[m][n]=a[m][o]*b[o][n]+c[m][n];
}
}
}
System.out.println("The resultant matrix is:-");
for(int p=0;p<3;p++)
{
for(int q=0;q<3;q++)
{
System.out.println(c[p][q]);
}
}
]

//tis will give u the output but u neeed to enter n dats the limit which in this case is 11...........
