Question

What is the output of the following code snippet?

Type "error" if error. If Note: pow (x,y) returns x raised to the power y(x∧y)
int main()
{
int n=5
std::stackstk;
int res =0;
for ( int i=1;i<=n;i++)
if (( i )%3==0)
{
while(Istk.empty ())
{
int va1=stk⋅top();
res += val;
stk.pop ();
}
else
stk.push ((i) * std::pow (−1,i));
}
std: : cout <}

Answer 1

The code snippet contains several syntax errors and cannot be compiled as it is. Therefore, it's not possible to determine the correct output; the appropriate answer is 'error' due to these compilation issues.

The given code has several syntax errors and it's not clear from the snippet what it is supposed to do because of those errors and potential missing parts. Assuming this is a C++ code snippet, the following issues are present:

• Missing semicolon after n=5.
• The definition of std::stack is wrong; it should be std::stack<int> stk;.
• There is a typo in while(!stk.empty()), instead of Istk.empty().
• The extraction operator << is used incorrectly in the std::cout statement, and also the output statement is incomplete.
• Incorrect symbol ⋅ is used instead of - for negative numbers in std::pow function call.
• There is a variable naming inconsistency with val and va1.

Due to these issues, the correct output cannot be determined and the code will not compile as it stands, hence the answer would be "error".
