pls tell me why my code gives output run time error and also explain with your code
#include
#include
using namespace std;
int main(int argc, char const *argv[]){
stack<int> s;
int no;
cin>>no;
int input;
int c;
while(no--){
cin>>input;
if(input==2){
cin>>c;
s.push(c);
}
if(input==1){
if(s.empty()){
cout<<"No Code"<<endl;
}
cout<<s.top()<<endl;
s.pop();
}
}
return 0;
}
@kshitiz.gzb
The runtime error is due to the statements
cout<<s.top()<<endl;
s.pop();
Particularly in the case when stack is empty.
You need to put the above two statements inside in an else block otherwise your code tries to print the top element and pop it even when the stack is empty giving you a runtime error.
Make this change and the rest of your code works fine.
