Question

How to use static cast to allow the compiler to check the casting in C++

Answer 1

#include <iostream>

int main() {
    char ch = 97;
    
    int *p = static_cast<int*>(&ch);
}




/*
run:

test.cpp: In function ‘int main()’:
test.cpp:6:14: error: invalid ‘static_cast’ from type ‘char*’ to type ‘int*’
    6 |     int *p = static_cast<int*>(&ch);
