随意赋值 表示刚学不到一礼拜 老师留的homework
#include<stdio.h>
int main()
{
int a=1;
short b=2;
long c=3;
float f=12.34;
double d=3.1415926;
char ch='A';
printf("a=%d\nb=%d\nc=%d\nf=%f\nd=%lf\nch=%c\n",a,b,c,f,d,ch);
return 0;
}
输出为：
a=1
b=2
c=3
f=12.340000
d=3.141593
ch=A
int main()
{
int a=1;

char ch='A';
printf("a=%d\nb=%d\nc=%d\nf=%f\nd=%lf\nch=%c\n",a,b,c,f,d,ch);
return 0;
}
输出为：
a=1
b=2
c=3
f=12.340000
d=3.141593
ch=A
