在C中直接输入整数 [英] Inputing integers straight across in C

问题描述

我正在上C语言入门课程，我想知道是否有一种方法可以直接输入整数并将它们平均在一起?我试图使我的程序尽可能整洁.

I'm in a beginner C course and I was wondering if there's a way to input integers straight across and averages them together? I'm trying to make my program nice and tidy as possible.

我想像这样直接输入整数:

I want to input integers straight across like:

输入温度，完成后输入00:

Enter the temperatures and Enter 00 when finished:

 60 80 97 42

 Average is: 69.75

我不想输入如下所示的整数:

I don't want to input integers like shown below:

输入温度，完成后输入00:75

Enter the temperatures and Enter 00 when finished: 75

输入温度，完成后输入00:80

Enter the temperatures and Enter 00 when finished: 80

输入温度，完成后输入00:46

Enter the temperatures and Enter 00 when finished: 46

输入温度，完成后输入00:91

Enter the temperatures and Enter 00 when finished: 91

平均为:73

推荐答案

#include <stdio.h>
#include <string.h>

int main(void){
    char input[64];
    double ave = 0.0, value;
    int count = 0;

    printf("Enter the temperatures and Enter 00 when finished:\n");
    while(1){
        if(1==scanf("%63s", input)){
            if(strcmp(input, "00") == 0)
                break;
            if(1==sscanf(input, "%lf", &value))
                ave += (value - ave) / ++count;
        }
    }
    if(count)
        printf("Average is: %g\n", ave);
    else
        printf("Input one or more values\n");

    return 0;
}
