实验 2 用C语言编写简单程序

 

#include<stdio.h>
int main(void)
{
 int x,y;

 printf("请输入x的值:");
 scanf("%d",&x);
  y=x*x;
 printf("%d=%d*%d\n",y,x,x);
 printf("%d*%d=%d\n",x,x,y);
 return 0;
}

 

 

#include<stdio.h>
int main()
{
 int i;
 long m;
 float f;
 double d;

 printf("sizeof(int)=%d,sizeof(i)=%d,&i=%x\n",sizeof(int),sizeof(i),&i);
 printf("sizeof(long)=%d,sizeof(m)=%d,&m=%x\n",sizeof(long),sizeof(m),&m);
 printf("sizeof(float)=%d,sizeof(f)=%d,&f=%x\n",sizeof(float),sizeof(f),&f);
 printf("sizeof(double)=%d,sizeof(d)=%d,&d=%x\n",sizeof(double),sizeof(d),&d);
}
