Can someone explain nested loops ?

Question

#include <iostream>
using namespace std;

int main() {

for (int i = 1; i <= 3; i++) {
for (int j = 1; j <= 2; j++) {
// code
}
}
return 0;
}

Answer 1

In this code, the for loop is inside another for loop. The nested for loop is executed 3 times, each time 2 times, for a total of 6 times. The other for loop is executed only 3 times. There are errors in your code. The correct syntax is i++, j++.
