Question

#include <iostream>
using namespace std;

int main() {
string a,z;
cin>>a;
int p= a.length();

for(int y=p-1 ;y==0;y--){
for(int i=0;i<p;i++){

z[i]=a[y];

}

}

cout<<z;

return 0;
}

Why is this code giving no output?

Answer 1

First mistake is putting y==0 which won't run the loop

Answer 2

It should be char z[20] instead of string z;

Answer 3

ya i changed that but its still not working
