Using function templates to get the max and min value in an array
<![CDATA[
#include <iostream>
using std::cout;
using std::endl;
template<class T> T max(const T* data, int size) {
T result = data[0];
for(int i = 1 ; i < size ; i++)
if(result < data[i])
result = data[i];
return result;
}
template<class T> T min(const T* data, int size) {
T result = data[0];
for(int i = 1 ; i < size ; i++)
if(result > data[i])
result = data[i];
return result;
}
int main() {
double data[] = {1.5, 4.6, 3.1, 1.1, 3.8, 2.1};
int numbers[] = {2, 22, 4, 6, 122, 12, 1, 45};
const int dataSize = sizeof data/sizeof data[0];
cout << "Minimum double is " << min(data, dataSize) << endl;
cout << "Maximum double is " << max(data, dataSize) << endl;
const int numbersSize = sizeof numbers/sizeof numbers[0];
cout << "Minimum integer is " << min(numbers, numbersSize) << endl;
cout << "Maximum integer is " << max(numbers, numbersSize) << endl;
return 0;
}
Minimum double is 1.1
Maximum double is 4.6
Minimum integer is 1
Maximum integer is 122
