Answer 1

You declared int a twice.

Remove int a = a+1;
Replace with a = a+1;
(or even better, a+=1;)

Global variable a never hits 10, while loop then runs infinite times.

Turn the local a to global a (by removing int) and it works! :)

int main()
{
int a=0;
int b=10;
int sum;
while (a<10) {
sum=a+b;
cout<<sum;
a= a+ 1; // declared twice
}

return 0;
}
