我试着从用户那里得到他们想要输入的号码。在菜单上。我已经得到了工作所需的一切,除了这个最低的数字。我不知道从这里到哪里去。我不知道怎样才能在交换机里找到号码。
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>
#define PAUSE system("pause")
#define CLEAR system("cls")
main() {
// Initialize variables
char choice;
int sum = 0;
int avg = 0;
int high = 0;
int low = 0;
int quit = 0;
int i = 0;
int num = 0;
int j = 0;
int prevNum;
do{
printf("What would you like to do\n"
"A: enter an integer\n"
"B: show sum\n"
"C: Show average\n"
"D: show Highest num\n"
"E: Show lowest\n"
"Q: quit\n");
scanf("%c", &choice);
CLEAR;
switch (choice) {
case 'A':
printf("Enter an Integer\n");
scanf("%i", &num);
j++;
sum = num + sum;
if (num > high)
high = num;
PAUSE;
break;
case 'B':
printf("The sum of al numbers entered is %i\n", sum);
PAUSE;
break;
case 'C':
avg = sum / j;
printf("The average of all numbers entered is %i\n",avg);
PAUSE;
break;
case 'D':
printf("The Highest number entered is %i\n", high);
PAUSE;
break;
case 'E':
printf("The lowest number entered is %i\n", low);
PAUSE;
break;
case 'Q':
quit = 1;
break;
} // end switch
} while (quit != 1);
PAUSE;
} // END MAIN
最佳答案
你可以使用:
if (num < low) {
low = num;
}
唯一的问题是第一个号码。由于您将
low
初始化为0
,因此用户输入的任何正数都不会低于此值。你需要特别对待第一个号码。您可以为此检查j
的值。然后在
A
情况下,测试这个变量。case 'A':
printf("Enter an Integer\n");
scanf("%i", &num);
j++;
sum = num + sum;
if (j == 1 || num > high)
high = num;
if (j == 1 || num < low)
low = num;
PAUSE;
break;
