Looping
Statements in C++
In C++, there are several looping statements that you can
use to repeat a block of code multiple times. The most commonly used looping
statements are:
1. **for loop**: The `for` loop allows you to specify an
initialization expression, a condition, and an increment or decrement
expression, all in a single line. The syntax for a `for` loop is as follows:
```cpp
for (initialization; condition; increment/decrement) {
// code to be
executed
}
```
Here's an example that prints the numbers from 1 to 5 using
a `for` loop:
```cpp
for (int i = 1; i <= 5; i++) {
cout << i
<< " ";
}
```
2. **while loop**: The `while` loop repeatedly executes a
block of code as long as the specified condition is true. The syntax for a
`while` loop is as follows:
```cpp
while (condition) {
// code to be
executed
}
```
Here's an example that prints the numbers from 1 to 5 using
a `while` loop:
```cpp
int i = 1;
while (i <= 5) {
cout << i
<< " ";
i++;
}
```
3. **do-while loop**: The `do-while` loop is similar to the
`while` loop, but the condition is checked at the end of the loop. This
guarantees that the loop body is executed at least once. The syntax for a
`do-while` loop is as follows:
```cpp
do {
// code to be
executed
} while (condition);
```
Here's an example that prints the numbers from 1 to 5 using
a `do-while` loop:
```cpp
int i = 1;
do {
cout << i
<< " ";
i++;
} while (i <= 5);
```
These are the three main looping statements in C++. Each of
them has its own use cases depending on the requirements of your program.
