Given code in the video is not working

#1

#include
#include
using namespace std;
bool checkExp(string s)
{
stackc;
for(int i=0;i<c.size();i++)
{
char curr=s[i];
if(curr==’(’)
{
c.push(curr);
}
else if(curr==’)’)
{
if(c.empty() || c.top()!=’(’ )
{
return false;
}
c.pop();
}
}
return true;
}
int main()
{
string expr;
cin>>expr;
bool isValid=checkExp(expr);
cout<<isValid;
return 0;
}
HERE IS THE SAME CODE IN THE VIDEO AND IT IS PRINTING 1 FOR BOTH TRUE AND FALSE CASES… KINDLY CHK AND ALSO UPDATE IN THE VIDEO

Hi,

the for loop in the function checkExp will never run in your code. You should mention s.size() rather than c.size() since you are traversing on the string.
