c++ template example
Example 1: c++ template function
template <class T>
void swap(T & lhs, T & rhs)
{
T tmp = lhs;
lhs = rhs;
rhs = tmp;
}
Example 2: function template
template <class T>
void swap(T & lhs, T & rhs)
{
T tmp = lhs;
lhs = rhs;
rhs = tmp;
}
void main()
{
int a = 6;
int b = 42;
swap<int>(a, b);
printf("a=%d, b=%d\n", a, b);
double f = 5.5;
double g = 42.0;
swap(f, g);
printf("f=%f, g=%f\n", f, g);
}
Example 3: template in c++
template <class T>
T Large(T n1, T n2)
{
return (n1 > n2) ? n1 : n2;
}
Example 4: c++ template
#include <iostream>
#include <string>
using namespace std;
int main() {
}
