I get this error ” invalid conversion from int* to int” when running my code.

Here is my code:

#include <iostream>
using namespace std;

int main() {
  int p = 20;
  int* ptr;
  ptr = p; //Invalid conversion.
}

What should I do?

    The cause: This error happens because you try to assign an integer value (i.e., p ) to an integer pointer. You must remember that pointers are used to store the address of a particular variable.

    Solution: You can solve this error by assigning the address of the variable p by using the & symbol.

    int p = 20;
int* ptr;
ptr = &p;
