1.有n个评委,他们给出score个分数,请用代码写出平均值,ave代表平均值 2022-10-15 13:17:10
int main() {
int n, i =1, score, sum = 0, ave;
printf("请输入评委人数:");
scanf("%d",&n);
while (i<=n) {
printf("请为参赛队打分:0~100:");
scanf("%d",&score);
sum += score;
i++;
}
ave = sum / n;
printf("平均值为%d",ave);
}
2.某旅游景点为吸引游客,旺季和淡季门票价格不同,旺季为每年5~10月,门票价为200元,
淡季门票价格是旺季的八折。无论淡季还是旺季,65岁及以上的老人免票,14岁以下的孩童半价,
其余游客全价。
请编写一个旅游景点门票计费程序
int main() {
//旺季:每年5~10月份,票价200
//淡季:旺季*80%
//人>=65免票&&人<14半价
int a=200,b,age,e=100;//a为旺季票价,age为岁数,b为月份,e为儿童旺季票价
double c = 200 * 0.8,d=200*0.5*0.8;//c为淡季票价,d为儿童淡季票价
printf("游客姓名:董某人\n请输入游览月份:");
scanf("%d", &b);
printf("请输入游客年龄:");
scanf("%d",&age);
if (age >= 65)
printf("免票");
else if (0 < age && age < 14&&b==5||b==6||b==7||b==8||b==9||b==10) printf("应购买门票价格为%d块",e);//儿童旺季价
else if (0 < age && age < 14 && b == 1 || b == 2 || b == 3 || b == 4 || b == 11 || b == 12) printf("应购买门票价格为%.1f块",d);//儿童淡季价
else if (14 < age && 14 < 65&& b == 5 || b == 6 || b == 7 || b == 8 || b == 9 || b == 10) printf("应购买门票价格为%d块",a);//正常旺季价
else if (14 < age && 14 < 65 && b == 1 || b == 2 || b == 3 || b == 4 || b == 11 || b == 12) printf("应购买门票价格为%.1f块",c);//正常淡季价
}
3.求某年某月的天数
int gf(int year, int mon)标签:14,int,小白刷题,age,C语言,&&,printf,旺季 From: https://www.cnblogs.com/djhyyds/p/16793982.html
{
switch (mon) {
case 2:
if (year % 4 == 0 && year % 100 != 0 || year % 400 == 0)
return 29;
else
return 28;
case 4:
case 6:
case 9:
case 11:
return 30;
default:
return 31;
}
}
int main() {
printf("%d", gf(1998, 7));
return 0;
}
