软件设计工具分为:请教一个简单的c语言问题

#include<stdio.h>
void dayin(int *i,int *j,int *k);
main()
{
int x1,x2,x3;
printf("input 1st num:");
scanf("%d",&x1);
printf("input 2nd num:");
scanf("%d",&x2);
printf("input 3rd num:");
scanf("%d",&x3);
dayin(&x1,&x1,&x1);

}
void dayin(int *i,int *j,int *k)
{printf("The numbers you have just input are: %d, %d, %d\n",*i,*j,*k); }
/*试试吧，我没调过，应该正确的*/

初学的，还请大家多多指教

#include <iostream.h>
void main()
{
int arr[3];
int *p;
p=arr;
for(int i=0;i<3;i++)
{
cout<<"请输入第"<<i+1<<"个数"<<endl;
cin>>arr[i];
}
cout<<*p<<endl;
cout<<*(p+1)<<endl;
cout<<*(p+2)<<endl;
}

编译：Turbo C++ 3.0

#include<stdio.h>
main()
{
float x1,x2,x3;
printf("input 1st num:");
scanf("%f",&x1);
printf("input 2nd num:");
scanf("%f",&x2);
printf("input 3rd num:");
scanf("%f",&x3);
printf("The numbers you have just input are: %f, %f, %f\n",x1,x2,x3);
return 0;
}

用函数是不是太麻烦了,你是不是要学习函数啊,f了
