Why this code is showing an error? Pls. Help

Question

But after removing the semicolon ; from the end of the for loop it has no error why so?

#include <iostream>
using namespace std;

int main() {
for(int i=0;i<7;i++);
cout<<i;
return 0;
}

Answer 1

Because you have declared i inside for loop and is not accessible outside the scope of that for loop.

Correct code.

#include <iostream>
using namespace std;

int main() {
int i;
for(i=0;i<7;i++);
cout<<i;
return 0;
}

Answer 2

the for loop doesn't have a semicolon at the end
