The program goes as follows:

#include

void main()

{

int i, j=1;

printf("Enter the value of the integer whose factorial has to be calculated");

scanf("%d",i);

while(j

i = i*(i-1);

i--;

printf("The factorial of the integer is:%d",i);

getch();

}

OTHER METHOD.............

#include

void main()

{

int n,f;

f=1;

printf("Enter the number:\n");

scanf("%d",&n);

while(n>0)

{

printf("%d",n);

f=f*n;

n--;

}

printf("The factorial of the integer is:%d",f);

getch();

}

another method

A very easy method,,,,,,

these is the work of 2nd year high school programming........... CVHS..

#include

int main()

{

char m;

int ans, i, n;

i=0;

m='y';

while((m=='y')(m=='Y'))

{

cout<<"Input a number ";

cin>>n;

if(n==0)

{

ans=1;

cout<<"The factorial of a number is "<

}

else

{

ans=1;

for(i=1;i<=n;i++)

{

ans=ans*i;

}

cout<<"The factorial of a number is "<

}

cout<<"\n Do you want to continue? (Y/N) ";

cin>>m;

}

return 0;

}

see,, its very easy!!!!

my new mathod

#include

main()

{

int i,j,div,mod;

clrscr();

printf("enter any number = ");

scanf("%d",&i);

for(j=1;j<=i;j++)

{

mod=i%j;

if(mod==0)

{

printf("%d*",j);

div=i/j;

i=div;

j=1;

}

if(j==i)

{

printf("%d",i);

}

getch();

}
