编写一个 C++ 程序，通过示例将两个数组相加。在此 C++ 数组相加示例中，我们允许用户输入数组大小和数组元素。接下来，我们使用 C++ for 循环将数组从 0 迭代到 size。
在 for 循环中，我们将两个数组的元素相加，并将它们分配给一个名为 add 的新数组。在这里，我们还使用 cout 语句在每个 for 循环迭代中显示结果。最后，我们使用另一个 for 循环来打印 add 数组的元素。
#include<iostream>
using namespace std;
int main()
{
int size, i, arr1[10], arr2[10], add[10];
cout << "\nPlease Enter the Array Size = ";
cin >> size;
cout << "\nPlease Enter the First Array Items = ";
for(i = 0; i < size; i++)
{
cin >> arr1[i];
}
cout << "\nPlease Enter the Second Array Items = ";
for(i = 0; i < size; i++)
{
cin >> arr2[i];
}
for(i = 0; i < size; i++)
{
add[i] = arr1[i] + arr2[i];
cout << arr1[i] << " + " << arr2[i] << " = " << add[i] << "\n";
}
cout << "\nThe Final Result of adding 2 One Dimensional Arrays = ";
for(i = 0; i < size; i++)
{
cout << add[i] << " ";
}
return 0;
}
在此数组相加示例中，我们删除了用于显示元素的额外 for 循环，并在执行相加后放置了一个 cout 语句。有关更多信息，请参阅 C++。
#include<iostream>
using namespace std;
int main()
{
int size, i, arr1[10], arr2[10], add[10];
cout << "\nPlease Enter the Array Size = ";
cin >> size;
cout << "\nPlease Enter the First Array Items = ";
for(i = 0; i < size; i++)
{
cin >> arr1[i];
}
cout << "\nPlease Enter the Second Array Items = ";
for(i = 0; i < size; i++)
{
cin >> arr2[i];
}
cout << "\nThe Final Result of adding 2 One Dimensional Arrays = ";
for(i = 0; i < size; i++)
{
add[i] = arr1[i] + arr2[i];
cout << add[i] << " ";
}
return 0;
}
Please Enter the Array Size = 5
Please Enter the First Array Items = 10 20 30 40 50
Please Enter the Second Array Items = 9 29 35 55 77
The Final Result of adding 2 One Dimensional Arrays = 19 49 65 95 127 C++ 程序，使用 While 循环将两个数组相加
#include<iostream>
using namespace std;
int main()
{
int size, i, arr1[10], arr2[10], add[10];
cout << "\nPlease Enter the Array Size = ";
cin >> size;
cout << "\nPlease Enter the First Array Items = ";
i = 0;
while(i < size)
{
cin >> arr1[i];
i++;
}
cout << "\nPlease Enter the Second Array Items = ";
i = 0;
while(i < size)
{
cin >> arr2[i];
i++;
}
cout << "\nThe Final Result of adding 2 One Dimensional Arrays = ";
i = 0;
while(i < size)
{
add[i] = arr1[i] + arr2[i];
cout << add[i] << " ";
i++;
}
return 0;
}
Please Enter the Array Size = 7
Please Enter the First Array Items = 1 2 3 4 5 6 7
Please Enter the Second Array Items = 10 11 12 13 14 15 16
The Final Result of adding 2 One Dimensional Arrays = 11 13 15 17 19 21 23
