2.8printf小练习

#include<stdio.h>

int main()
{
	int data1 = 10;
	int data2 = 6;
	int data3;
	float data4;
	
	printf("这是我写的第一个c代码\n");
	printf("there are two orgian data:%d,%d\n",data1,data2);
	
	data3 =data1 + data2;
	
	printf("这两个数的和为：%d\n",data3);
	
	data3 =data1 - data2;
	
	printf("这两个数的减为：%d\n",data3);
	
	data3 =data1 * data2;
	
	printf("这两个数的乘为：%d\n",data3);
	
	data4 =(float)data1 / data2;	//这里要用float进行强制转换
	
	printf("这两个数的除为：%f\n",data4);
	
	
	return 0;
