C# Loops and Jump Statements
Duration : 00:03:00
for loop:
A for loop is used for iterating over a sequence (like a list or range) and executing a block of code for each item.Example:
for (int i = 1; i <= 5; i++)
{
Console.WriteLine(i);
}
nested for loop:
A nested for loop is a for loop inside another for loop, commonly used for iterating over 2D data structures.Example:
for (int i = 0; i < 3; i++)
{
for (int j = 0; j < 2; j++)
{
Console.WriteLine($"{i} {j}");
}
}
infinite for loop:
An infinite for loop runs indefinitely and is often used with a break statement to exit when a certain condition is met.Example:
while (true)
{
Console.WriteLine("This is an infinite loop");
break; // Exit the loop
}
while loop:
A while loop repeatedly executes a block of code as long as a specified condition is true.Example:
int count = 0;
while (count < 5)
{
Console.WriteLine(count);
count++;
}
do while loop:
Some languages have a do-while loop that ensures the block of code is executed at least once before checking the condition.Example:
int num = 0;
do
{
Console.WriteLine(num);
num++;
} while (num < 5);
break statement:
The break statement is used to exit a loop prematurely when a certain condition is met.Example:
for (int i = 1; i < 10; i++)
{
if (i == 5)
{
break;
}
Console.WriteLine(i);
}
continue statement:
The continue statement is used to skip the current iteration of a loop and proceed to the next iteration.Example:
for (int i = 1; i <= 5; i++)
{
if (i == 3)
{
continue;
}
Console.WriteLine(i);
}
goto statement:
The goto statement is used in some programming languages to transfer control to a labeled section of code.Example:
int main() {
int i = 1;
start:
if (i <= 5) {
std::cout << i << std::endl;
i++;
goto start; // This goes back to the "start" label
}
return 0;
}
