4.輸入三數，並求此三數中最大值與最小值的差與平均值
#include <stdio.h>
main()
{
float a,b,c,d;
printf("Please enter first number:");
scanf("%f",&a);
printf("Please enter 2nd number:");
scanf("%f",&b);
printf("Please enter 3rd number:");
scanf("%f",&c);
if ( a > b && b > c){
printf("a-c=%f \n",a-c );
printf("Average =%f" ,(a+c)/2);}
if ( a > c && c > b){
printf("a-b=%f \n",a-b);
printf("Average =%f" ,(a+b)/2);}
if ( b > a && a > c){
printf("b-c=%f \n",b-c);
printf("Average =%f" ,(b+c)/2);}
if ( c > a && a > b){
printf("c-b=%f \n",c-b);
printf("Average =%f" ,(b+c)/2);}
if ( b > c && c > a){
printf("b-a=%f \n",b-a);
printf("Average =%f ",(b+a)/2);}
if ( c > b && b > a){
printf("c-a =%f \n",c-a);
printf("Average =%f ",(c+a)/2);}
scanf("%f",&d);
}
我剛才寫的 compile過 也run過
答案正確
不過程式或許還可精簡,小弟才疏學淺,請各位大大不吝指教~~
