#include <stdio.h>
#define a 97
int main()
{
char c = 'a';
int n = a; //將c賦值給n
float f = a; //將c賦值給f
double d = a; //將c賦值給d
printf("%d\n",n);
printf("%f\n",f);
printf("%lf\n",d);
return 0;
}
根據(jù)上一節(jié)課的內(nèi)容可以這樣寫
#include<stdio.h>
int main(){
int x = 10;
int y = -3;
printf("x + y =%d\n",x + y);
printf("x - y =%d\n",x - y);
printf("x * y =%d\n",x * y);
printf("x / y =%d\n",x / y);
printf("x% y =%d\n",x% y);
#include<stdio.h>
int main(){
int a,b,c,d,e;
a = 5;
b = 9;
c = 18;
d = a + c;
e = d - b;
printf("%d\n%d\n%d\n%d\n",a + d,c - e,b * a,d - a / e);
#include<stdio.h>
int main(){
int c = 97;
double z,x;
z = x;
x = c;
printf("%d\n",c);
printf("%f\n",x);
printf("%f\n",z);
