#include<stdio.h>

void main()

{

double a,b,c,s,v;

printf("Input a,b,c: ");

scanf("%d%d%d",&a,&b,&c);

s=a*b+b*c+a*c;

v=a*b*c;

printf("a=%d,b=%d,c=%d ",a,b,c);

printf("s=%f ",s,"v=%d ",v);

}

#include <stdio.h>

void main()

{
float a, b, c, s, v;
printf("Input a,b,c: ");
scanf_s("%f%f%f", &a, &b, &c);
s = 2 * ( a * b + b * c + a * c );
v = a * b*c;
printf("a=%f, b=%f, c=%f. ", a, b, c);
printf("s=%f ", s, "v=%f ", v);

}

运行结果：

Input a,b,c:
1 2 3
a=1.000000, b=2.000000, c=3.000000.
s=22.000000
