In Python, therange()function returns a sequence of numbers. For example, # generate numbers from 0 to 3values = range(0,4) Here,range(0, 4)returns a sequence of0,1,2,and3. Since therange()function returns a sequence of numbers, we can iterate over it using aforloop. For example...
Range-based for loop 在范围上执行for循环。 用作更易读的,相当于传统的用于循环操作范围内的值,例如容器中的所有元素。 句法 attr(optional) for ( range_declaration : range_expression ) loop_statement attr - any number of attributes range_declaration - a declaration of a named variable, ...
基于范围的for循环使用了一个称为范围变量(Range Variable)。每次基于范围的for循环迭代时,它都会复制下一个数组元素到范围变量。例如,第一次循环迭代,范围变量将包含元素0的值;第二次循环迭代,范围变量将包含元素1的值,以此类推。 以下是基于范围的for循环的一般格式: ...

#include <iostream> #include <vector> int main() { std::vector<int> numbers = {1, 2, 3, 4, 5}; // Using a range-based for loop to iterate over the elements of the vector for (int number : numbers) { std::cout << number << " "; } return 0; } Output: 1 2 3 4 5 ...
print("While loop finished.") 4. 列表推导式(隐式循环) 通过简洁的语法生成列表,内部基于循环逻辑。 示例 python # 生成平方数列表 squares = [x**2 for x in range(10)] print(squares) # 输出: [0, 1, 4, 9, 16, 25, 36, 49, 64, 81] ...

Let's see some simple examples of For Loop in VBA. Example 1: Use VBA For Loop to print numbers from 1 to 10 in excel. In this example, we have a range "A1:A10”, and we have to fill this range with numbers from 1-10.To accomplish this, we can use the below code: Sub For...
