How to resolve the error: "invalid conversion from int to int*"
The “invalid conversion from into to int*” error is encountered when an integer pointer is assigned an integer value.
Remember: pointers are used to store the address of a particular variable.
Code
Error
In the code below, when we try to assign an integer value (i.e., p ) to an integer pointer, it throws an error.
#include <iostream>using namespace std;int main() {int p = 20;int* ptr;ptr = p; //Invalid conversion.}
### Correct way
To resolve this error, assign the address of the variable p by using the & symbol.
int p = 20;
int* ptr;
ptr = &p;
The
&symbol is used to return the address of a particular variable.
