好的,以下是代码实现:
```python
a = float(input("请输入第一个实数:"))
b = float(input("请输入第二个实数:"))
c = float(input("请输入第三个实数:"))
if a <= b <= c:
print(a, b, c)
elif a <= c <= b:
print(a, c, b)
elif b <= a <= c:
print(b, a, c)
elif b <= c <= a:
print(b, c, a)
elif c <= a <= b:
print(c, a, b)
else:
print(c, b, a)
```
代码中,我们通过多个 if 语句来判断三个实数的大小关系,最终按递增顺序输出。

输入3个实数,按递增顺序输出。注意使用if语句编写程序。C++
好的,以下是 C++ 的代码实现:
```c++
#include <iostream>
using namespace std;
int main() {
float a, b, c;
cout << "请输入三个实数:";
cin >> a >> b >> c;
if (a <= b && b <= c) {
cout << a << " " << b << " " << c;
}
else if (a <= c && c <= b) {
cout << a << " " << c << " " << b;
}
else if (b <= a && a <= c) {
cout << b << " " << a << " " << c;
}
else if (b <= c && c <= a) {
cout << b << " " << c << " " << a;
}
else if (c <= a && a <= b) {
cout << c << " " << a << " " << b;
}
else {
cout << c << " " << b << " " << a;
}
return 0;
}
```
代码中,我们通过多个 if 语句来判断三个实数的大小关系,最终按递增顺序输出。值得注意的是,C++ 中的输入输出需要使用 `cin` 和 `cout`。
B、输入三个实数,按递增顺序输出。 注意用if语句写程序。用c++做
好的,这是一个常见的编程题目。以下是用C++编写的程序:
```cpp
#include <iostream>
using namespace std;
int main() {
double a, b, c;
cout << "请输入三个实数,用空格分隔:" << endl;
cin >> a >> b >> c;
if (a <= b) {
if (b <= c) {
cout << a << " " << b << " " << c << endl;
}
else {
if (a <= c) {
cout << a << " " << c << " " << b << endl;
}
else {
cout << c << " " << a << " " << b << endl;
}
}
}
else {
if (a <= c) {
cout << b << " " << a << " " << c << endl;
}
else {
if (b <= c) {
cout << b << " " << c << " " << a << endl;
}
else {
cout << c << " " << b << " " << a << endl;
}
}
}
return 0;
}
```
该程序首先提示用户输入三个实数,然后使用if语句嵌套来判断它们的大小关系,并按递增顺序输出。需要注意的是,当有两个或三个数相等时,输出的顺序可能不是严格递增的。
