Question 1 : Operator Precedence

a) What is the value of variable n after the following C++ statements are executed?

int n;

n = 8+3.5*(int)4.5/2;

b) What is the value of variable n after the following C++ statements are executed?

int a = 15, b = 2, c = 7;

int n;

n = a/b*(c%2 + 4.5);

Solution1.cpp

#include <iostream>//header file for input output function

using namespace std;//it tells the compiler to link stdnamespace

int main()
{//main function
int n;

n = 8+3.5*(int)4.5/2;
cout<<\"value of n is \"<<n;
return 0;
}

output

value of n is 15

Solution2.cpp

#include <iostream>//header file for input output function
using namespace std;//it tells the compiler to link stdnamespace

int main()
{//main function
int a = 15, b = 2, c = 7;//variable assignment

int n;//variable declaration

n = a/b*(c%2 + 4.5);
cout<<\"value of n is \"<<n<<endl;
return 0;
}

output

value of n is 38
