Function Templates

//Prototype:

template <class TYPE1, class TYPE2>

void array_copy(TYPE1 dest[], TYPE2 source[], int size);

//A later definition:

template <class TYPE1, class TYPE2>

void array_copy(TYPE1 dest[], TYPE2 source[], int size) {

for(int i=0; i < size; ++i)

dest[i] = source[i];

}

//The client can call this function using:

int int_array1[100], int_array2[100], int_array3[20];

float real_array[100];

char char_array[20];

array_copy(int_array1, int_array2, 100);

array_copy(int_array3, int_array1, 20);

array_copy(real_array, int_array1, 100);

array_copy(int_array1, char_array, 20);
