Question

int a=15 ; int b=3; int temp;
temp=a;
a=b;
b=temp;
cout<<temp/a;

Answer 1

int a=15 ; int b=3; int temp;

temp=a; // temp is 15, a is 15, b is 3
a=b; // temp is 15, a is 3, b is 3
b=temp; // temp is 15, a is 3, b is 15
cout<<temp/a; // temp/a is 15/3

// outputs 5

Answer 2

a=15 , b=3
temp= a , a=b, b=temp
temp=15 , a=3, b=15
so temp/a=5

Answer 3

5

Answer 4

temp=15
a=3
b=temp

so what you are doing is dividing temp(15)/a(3)
