Can someone check if I am doing these right please, thanks ?

```
int a=3, b=5, x;
x= a/b + b/a +a%b + b%a; cout << x; // x=0+1+0+1= 2
y=float(b/a)+ float(b)/a; cout << y; // y=1.6+1=2.6
z=a*b/2; cout << z; // z= 4
w=pow(b, a)+sqrt(a+b); cout << w; // w=125+2sqrt(2)
int a=4, b=7, x;
a++; --b;
x=a+b; cout<<"x"<< x; //x=11
a=4; b=8
x=a++*--b; cout<<"x="<< x; //x=35
a=3; b=5;
a+=3+b; b*=2;
x=a+b; cout<< "x="<< x; //x=13
```
