#include <iostream> using namespace std; /* this program is to find factorial of any number*/ int main() { int factorial,n,i; cout<< "enter any positive integer number:"<<endl; cin>>n; for (i=1;i<=n;i++) {factorial*=i}; cout << "factorial of "<<n<<"="<<factorial<<endl; return 0; }

umm also.. for loop doesn't need semicolon to end it after curly brackets.. {factorial*=i;}

it should be {factorial *=I;} //semi colon should be inside the bracket and you must declare value of factorial as 1 otherwise the some value of factorial will be used for multiplication
