أكتب برنامج باستخدام الدالة switch case يطلب من المستخدم إدخال رقم وفق شروط

int main(){
int n,mu=1, sum=0;
char c;
do{cout<<"enter numbers";
cin>>n;
cout<<"press leter(p)to print primry 
number"<<endl;
cout<<"press leter(m)to print fact number"<<endl;
cout<<"press leter(s)to print sum number"<<endl;
cout<<"press leter(f)to print factors 
number"<<endl;
cout<<"press leter(x)to print multiply 
number"<<endl;
cout<<"press leter (O) to print oven 
number"<<endl;
cout<<"press(another leter)to print square 
number"<<endl;
cout<<"press leter (e) for exit"<<endl;
cin>>c;
switch(c)
{case'p':{
int f=1;
for(int j=2;j<n;j++)
{if(n%j==0)

if(f==1)
cout<<n<<"is primary"<<endl;

break;
