这是一个C ++程序,用于打印给定数组的维数。
Here template() function is used to find out the current size of array. Then recursively call it till the last dimension of array.
#include <iostream>
using namespace std;
template <typename t, size_t n>
void printDimensionsOfArray(const t (&a)[n]) {
cout << n;
}
template <typename t, size_t n, size_t m>
void printDimensionsOfArray(const t (&a)[n][m]) {
cout << "Dimensions of the Array is: "<<n << " x ";
printDimensionsOfArray(a[0]);
}
int main() {
int a[6][7];
printDimensionsOfArray(a);
return 0;
}输出结果
Dimensions of the Array is: 6 x 7
