📜  TCS 编码练习题 | 2个数字的平均值

给定两个数字,任务是使用命令行参数找到两个数字的平均值。

例子:

Input: n1 = 10, n2 = 20
Output: 15

Input: n1 = 100, n2 = 200
Output: 150

方法:

  • 由于数字是作为命令行参数输入的,因此不需要专用的输入行
  • 从命令行参数中提取输入数字
  • 提取的数字将是字符串类型。
  • 将这些数字转换为整数类型并将其存储在变量中,比如 num1 和 num2
  • 使用公式 ((num1 + num2)/2) 求数字的平均值
  • 打印或返回平均值

程序:

C
// C program to compute the average of two numbers
// using command line arguments
  
#include 
#include  /* atoi */
  
// Function to compute the average of two numbers
int average(int a, int b)
{
    return (a + b) / 2;
}
  
// Driver code
int main(int argc, char* argv[])
{
  
    int num1, num2;
  
    // Check if the length of args array is 1
    if (argc == 1)
        printf("No command line arguments found.\n");
  
    else {
  
        // Get the command line argument and
        // Convert it from string type to integer type
        // using function "atoi( argument)"
        num1 = atoi(argv[1]);
        num2 = atoi(argv[2]);
  
        // Find the average and print it
        printf("%d\n", average(num1, num2));
    }
    return 0;
}


Java
// Java program to compute the average of two numbers
// using command line arguments
  
class GFG {
  
    // Function to compute the average of two numbers
    static int average(int a, int b)
    {
        return (a + b) / 2;
    }
  
    // Driver code
    public static void main(String[] args)
    {
  
        // Check if length of args array is
        // greater than 0
        if (args.length > 0) {
  
            // Get the command line argument and
            // Convert it from string type to integer type
            int num1 = Integer.parseInt(args[0]);
            int num2 = Integer.parseInt(args[1]);
  
            // Find the average
            int res = average(num1, num2);
  
            // Print the average
            System.out.println(res);
        }
        else
            System.out.println("No command line "
                               + "arguments found.");
    }
}
