使用c语言在方法中编写汽车减速,每次递减10分钟
你好，意思是不是速度每次递减10啊，我用循环语句，使速度每次递减10，直至速度为0。把源程序复制一下
#includestdio.h
#includestdlib.h
#includestring.h
int main()
{
int speed;
printf("please input the speed:\n");
scanf("%d",speed);
printf("begin slow down...\n");
while(speed=0)
{
printf("now the speed is:%d\n",speed);
speed=speed-10;
}
printf("now the speed is:0(the car stop)\n");
return 0;
}
运行结果如下，如果有什么不明白的还可以问我
C语言编程：定义一个汽车结构体？
按照题目要求编写的C语言汽车结构体程序如下
#includestdio.h
struct car{
float petrol;
}c1={0};
struct car refuel(struct car c){
c.petrol=c.petrol+2;
return c;
}
int main(){
int i;
for(i=0;i5;i++){
c1=refuel(c1);
printf("%.2f\n",c1.petrol);
}
return 0;
}
C语言编程：按题目要求从键盘输入乘车的起步价及行车公里数，输出车费？
按照题目要求编写的C语言程序如下
#includestdio.h
int main(){
int price,kilometre;
float payment;
printf("请输入起步价：");
scanf("%d",price);
printf("请输入行车公里数：");
scanf("%d",kilometre);
if(price==4){
payment=4+(kilometre-3)*1.2;
printf("应付车资为%.2f。",payment);
}else if(price==5){
payment=5+(kilometre-3)*1.5;
printf("应付车资为%.2f。",payment);
}else if(price==6){
payment=6+(kilometre-3)*1.8;
printf("应付车资为%.2f。",payment);
}else{
printf("无此起步价。");
}
return 0;
}
