对于想了解Windows Powershell Do While 循环的读者,本文将提供新的信息,我们将详细介绍powershellfor循环,并且为您提供关于2-18 分别用 for、while 和 do-while 循环语句以及递归方法计算 n!,并输出算式、2-4 Java 循环语句之 while , do...while、AWS is updating minimum requirements for AWS Tools for PowerShell to Windows PowerShell 3.0 and ....、C++ while 循环 v[i++] vs i++ in while body的有价值信息。
On January 14th 2020 Microsoft ended extended support for Windows Server 2008 and Windows Server 2008 R2. The oldest supported Windows Server version, Windows Server 2012, comes with Windows PowerShell 3.0 and .NET Framework 4.5.
The legacy variant of AWS Tools for PowerShell (AWSPowerShell) is currently compatible with Windows PowerShell 2.0 and .NET Framework 3.5. Starting May 1st 2020, AWS will require Windows PowerShell 3.0+ and .NET Framework 4.5+ as prerequisite for all new releases of AWSPowerShell. The existing versions of AWSPowerShell that are compatible with Windows PowerShell 2 and .NET Framework 3.5 will continue to be available for download from PowerShell Gallery, but will not be updated or supported.
What do I need to do?
If you are using modular or bundled variants of AWS Tools for PowerShell (AWS.Tools or AWSPowerShell.NetCore) , you are not impacted. No action is required.
If you are running a legacy variant of AWS Tools for PowerShell (AWSPowerShell) on Windows Server 2012 or higher, that already come with Windows PowerShell 3.0, or higher, and .NET Framework 4.5, or higher, you are not impacted. No action is required.
If you are running a legacy variant of AWS Tools for PowerShell (AWSPowerShell) on Windows Server 2008 or Windows Server 2008 R2 with Windows PowerShell 3.0, or higher, and .NET Framework 4.5, or higher, installed, you are not impacted, but please follow Microsoft guidelines on upgrading to the latest OS version
If you are running a legacy variant of AWS Tools for PowerShell (AWSPowerShell) on Windows Server 2008 or Windows Server 2008 R2 with Windows PowerShell 2.0, or .NET Framework 4.0, or lower, please upgrade to Microsoft Windows 2012 or higher.
If you choose not to upgrade your OS version, please upgrade Windows PowerShell to version 3.0, or higher and .NET Framework to version 4.5, higher.
If you cannot upgrade from Windows PowerShell 2.0 and .NET Framework 3.5 without impacting other workloads, please install PowerShell Core 6.0 alongside the existing PowerShell 2.0 version and switch to the new PowerShell executable. Then follow these detailed instructions to install AWSPowerShell.NetCore on Windows.
C++ while 循环 v[i++] vs i++ in while body
如何解决C++ while 循环 v[i++] vs i++ in while body?
我有一个关于在 while 循环中迭代的问题。所以假设我们有一个大小为 10 的向量,元素从 0 到 9。我们有一个只迭代一次的 for 循环,在 for 循环中我们有一个 while 循环。当我打印循环时,我得到了两种不同的结果,但我不确定为什么。
vector<int> v(10);
for(int i = 0; i < v.size(); i++){
v[i] = i;
}
int j = 0;
for(int i = 0; i < 1; i++){ // first loop
while(v[j] != 5){
cout << v[j]; //prints 0 1 2 3 4
j++;
}
}
for(int i = 0; i < 1; i++){ //second loop
while(v[j++] != 5){
cout << v[j]; //prints 1 2 3 4 5
}
}
解决方法
j++ 会增加 j 的值,但会在增加之前返回 j 的原始值。
int i =0;
int j = 0;
i = 1;
j = i++;
(i is 2,j is 1)

,
后缀递增在概念上复制内存中的操作数,递增原始操作数,最后产生副本的值。
下面的代码片段相当简单。打印 j 的内容后,vector 已递增。
vector<int> v(10);
for(int i = 0; i < v.size(); i++){
v[i] = i;
}
int j = 0;
for(int i = 0; i < 1; i++){ // first loop
while(v[j] != 5){
cout << v[j]; //prints 0 1 2 3 4
j++;
}
}
现在,让我们看看第二个循环。
vector<int> v(10);
for(int i = 0; i < v.size(); i++){
v[i] = i;
}
int j = 0;
for(int i = 0; i < 1; i++){ // second loop
// values of j are 0 1 2 3 4
while(v[j++] != 5){
// values of j are 1 2 3 4 5 because it has been incremented
cout << v[j]; //prints 1 2 3 4 5
}
}
vector<int> v(10);
for (int i = 0; i < v.size(); i++) {
v[i] = i;
}
int j = 0;
for (int i = 0; i < 1; i++) { // first loop
while (v[j] != 5) {
cout << v[j]; //prints 0 1 2 3 4
j++;
}
}
j = 0;
for (int i = 0; i < 1; i++) { //second loop
while (v[j++] != 5) {
cout << v[j]; //prints 1 2 3 4 5
}
}
使用单个 for 循环将有助于更好地理解代码,因为循环的两个条件相同。
vector<int> v(10);
for (int i = 0; i < v.size(); i++) {
v[i] = i;
}
int j = 0;
for (int i = 0; i < 1; i++) { // first loop
while (v[j] != 5) {
cout << v[j]; //prints 0 1 2 3 4
j++;
}
// joined the end of the first loop and the start of the second loop
j = 0;
while (v[j++] != 5) {
cout << v[j]; //prints 1 2 3 4 5
}
}
