+The `do/while` loop is a variant of the `while` loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.

+## 2. C++ while Loop
+
+The `while`loop loops through a block of code as long as a specified condition is true:
+
+### Syntax
+```cpp
+while (condition) {
+  // code block to be executed
+}
+
+```
+
+## 3. Example 1: Display Numbers from 1 to 5
+
+The program uses a while loop to print numbers from 1 to 5 to the console.
+```cpp
+#include <iostream>
+
+using namespace std;
+
+int main() {
+    int i = 1;
+    while (i <= 5) {
+        cout << i << endl;
+        ++i;
+    }
+    return 0;
+}
+
+```

+
+### Syntax

+ ## 1. What is the For Loop in C++?
 
+A For loop is a repetition control structure that allows us to write a loop that is executed a specific number of times. The loop enables us to perform n number of steps together in one line. 
+
+### Syntax: 
+```cpp
+for (initialization expr; test expr; update expr)
+{    
+     // body of the loop
+     // statements we want to execute
+}
+```

+
+## 2. Explain the Syntax of For Loop in C++.
+
+### Syntax: 
+```cpp
+for (initialization expr; test expr; update expr)
+{    
+     // body of the loop
+     // statements we want to execute
+}
+```
+Here,
+
+Initialization – this expression initializes variable(s) and is executed only once.
+
+Condition – if the specified test condition is True, the body of the for loop is executed. In case the test condition returns False, the for loop is terminated.
+
+Update – this expression updates the value of initialized variables and then the condition is evaluated again.
+
+## 3. C++ for Loop Example
+
+The program uses a for loop to print "Hello World!" five times to the console.
+
+## Example
+```cpp
+
+#include <iostream>
+
+using namespace std;
+
+int main() {
+        for (int i = 1; i <= 5; ++i) {
+        cout << i << " ";
+    }
+    return 0;
+}
+```
+
+## 4. C++ Infinite for Loop
+
+The program uses a for loop without any conditions, which creates an infinite loop that continuously prints "This loop will run forever." to the console.
+
+## Example
+```cpp
+#include <iostream>
+
+using namespace std;
+
+int main() {
+    for (;;) {
+        cout << "This loop will run forever." << endl;
+    }
+    return 0;
+}
+
+```
+## 5. C++ Nested for Loop
+The program uses nested for loops to iterate through values of i from 1 to 3 and j from 1 to 2, printing each combination to the console.
+
+## Example 
+```cpp
+#include <iostream>
+
+using namespace std;
+
+int main() {
+    for (int i = 1; i <= 3; ++i) {
+        for (int j = 1; j <= 2; ++j) {
+            cout << "i = " << i << ", j = " << j << endl;
+        }
+    }
+    return 0;
+}
