When initializing a const int with a float literal, the value that is stored in the const int may be incorrect.


Use one of the following as workarounds:
  • Use an integer literal.
  • Cast the float literal to an int.
  • Create a const float variable and assign the float literal to it. Then assign that const float to the const int.

#include <iostream>
const int ConstVal = 75.0;
int main()
    std::cout << "ConstVal = " << ConstVal << std::endl;
    return 0;
Note You find that the "ConstVal" value is an incorrect int type value.
