The while loop executes a block of code as long as a certain condition is true. The syntax of the while loop is as follows:
while (condition)
{
// Code to execute while the condition is true
}
Example:
int i = 1;
while (i <= 5)
{
Console.WriteLine(i);
i++;
}
The do-while loop is similar to the while loop, but it executes the block of code at least once before checking the condition. The syntax of the do-while loop is as follows:
do
{
// Code to execute at least once
} while (condition);
Example:
int i = 1;
do
{
Console.WriteLine(i);
i++;
} while (i <= 5);
The for loop executes a block of code a specified number of times. The syntax of the for loop is as follows:
for (initialization; condition; increment)
{
// Code to execute while the condition is true
}
Example:
for (int i = 1; i <= 5; i++)
{
Console.WriteLine(i);
}
The foreach loop is used to iterate over elements of an array or collection. The syntax of the foreach loop is as follows:
foreach (type element in collection)
{
// Code to execute for each element
}
Example:
int[] numbers = { 1, 2, 3, 4, 5 };
foreach (int number in numbers)
{
Console.WriteLine(number);
}
