Description

Create function template to compare two arguments of the same type with the equality operator ==

Demo Code

#include <iostream>

template <typename T>
bool isEqualTo(const T&, const T&);

int main(int argc, const char* argv[]) {
    int i1 = 5;/*from  w  w  w  . j a va 2  s.  co  m*/
    int i2 = 6;

    double d1 = 1.5;
    double d2 = 1.5;

    char c1 = 'X';
    char c2 = 'x';

    std::cout << i1 << " == " << i2 << " : "
              << (isEqualTo(i1, i2) ? "true" : "false") << std::endl;
    std::cout << d1 << " == " << d2 << " : "
              << (isEqualTo(d1, d2) ? "true" : "false") << std::endl;
    std::cout << c1 << " == " << c2 << " : "
              << (isEqualTo(c1, c2) ? "true" : "false") << std::endl;

    return 0;
}
// comparison operator
template <typename T>
bool isEqualTo(const T& c1, const T& c2) {
    return c1 == c2;
}
