Question

C程序检验。请问有什么错误，执行时总是提示； error C2085: 'a' : not in formal parameter list

#include<stdio.h>
int main()
float a,b,c,t;
scanf("%f,%f,%f",&a,&b,&c);
if(a>b)
{t=a;a=b;t=b;}
if(a>c)
{t=a; a=c; c=t;}
if(b>c)
{t=b; b=c; c=t;}
print("%a5.2f,%5.2f,%5.2f\n");
return 0;
}

Answer 1

这话话的意思是 a　　不是格式参数列表　
应该这样写
printf("%5.2f,%5.2f,%5.2f",a,b,c);

Answer 2

#include<stdio.h>
int main()
{float a,b,c,t;
scanf("%f,%f,%f",&a,&b,&c);
if(a>b)
{t=a;a=b;t=b;}
if(a>c)
{t=a; a=c; c=t;}
if(b>c)
{t=b; b=c; c=t;}
print("%5.2f,%5.2f,%5.2f\n",a,b,c);
return 0;
}
