This program made in MinGW should decompose numbers in prime factors. MinGW doesn’t say that there is on error, but the program does nothing:

#include<iostream.h>
#include<math.h>
int main(void)
{
int i,j,a,b=1;
cout<<“Introduceti numarul”<<endl;
cin>>a;
struct descomp
{int baza,exp;};
descomp x[20];
for(i=1;i<=a;i++)
{
j=0;
while(a%i==0)
{
a=a/i;
j+=1;
}
if(j>=1)
{
x[b].baza=i;
x[b].exp=j;
b+=1;
}
}
for(i=1;i<=b;i++)
cout<<x[i].baza<<”^”<<x[i].exp<<endl;
return 0;
}

What is wrong with it?
