错了4,8,11,13

@Yu09217777
1.很多数据类型有些问题
如:
n = 500 / 3;
程序会先计算500/3=166,再将166转为double类型。 可以改为:
n = 500 / 3.0;
其他位置同理
2.关于#8#13:
取 π=3.141593
3.关于#8:
每行一个数字
附AC代码:
#include <bits/stdc++.h>
using namespace std;
int main(){
int q;
cin >> q;
if (q == 1){
cout << "I love Luogu!";
}else if (q == 2){
int s,c;
s = 2 + 4;
c = 10 - s;
cout << s << " " << c;
}else if (q == 3){
int m,n,sum;
m = 14 / 4;
sum = 4 * m;
n = 14 % 4;
cout << m << endl;
cout << sum << endl;
cout << n << endl;
}else if (q == 4){
double n;
n = 500 / 3.0;
cout << fixed << setprecision(3) << n;//修改
}else if (q == 5){
int t;
t = (260 + 220) / (12 + 20);
cout << t;
}else if (q == 6){
cout << sqrt (6 * 6 + 9 * 9);
}else if (q == 7){
int a,b,c;
a = 100 + 10;
b = a - 20;
c = 0;
cout << a << endl;
cout << b << endl;
cout << c << endl;
}else if (q == 8){
const double pi = 3.141593;//修改
cout << pi * 5 * 2 << endl << 5 * 5 * pi << endl << 4 / 3.0 * pi * 5 * 5 * 5; //修改
}else if (q == 9){
int sum;
sum = (((1 + 1) * 2 + 1) * 2 + 1) * 2;
cout << sum;
}else if (q == 10){
cout << (15 + 7.5 * 10) / 10;
}else if (q == 11){
cout << 100.0 / (8 - 5);//修改
}else if (q == 12){
int m;
char x;
m = 'M'- 65 + 1;
x = 65 + 18 - 1;
cout << m << endl;
cout << x << endl;
}else if (q == 13){
double y1,y2,sum,pi = 3.141593;//修改
y1 = 4 * 4 * 4 * 4 / 3.0 * pi;//修改
y2 = 10 * 10 * 10 * 4 / 3.0 * pi;//修改
sum = y1 + y2;
cout << (int)pow(sum,1 / 3.0 );//修改
}else if (q == 14){
cout << 50;
}
return 0;

@凉蚊子LLL 再问大神一个问题:怎么根据测试点错误修改代码,看的我很懵

8题π=3.141593,≠3.14159!!!
