Here’s an English description of loop structures in Dart:
Loop Structures in Dart
In Dart, loop structures are used to repeatedly execute a block of code until a certain condition is met. Dart provides several main types of loop structures, including the for loop, while loop, do-while loop, and for-in loop. Below is a detailed introduction and examples of these loop structures.
1. for Loop
The for loop is used a block of code a known number of times.
dart
for (initialization; condition; increment/decrement) {
// Loop body
}
Example:
dart
for (int i = 0; i < 5; i++) {
print('Iteration: $i');
}
2. while Loop
The while loop repeatedly executes a block of code as long as the condition is true.
dart
while (condition) {
// Loop body
}
Example:
dart
int count = 0;
while (count < 5) {
print('Count: $count');
count++;
}
3. do-while Loop
The do-while loop is similar to the while loop, but it executes the loop body at least once before checking the condition.
dart
do {
// Loop body
} while (condition);
Example:
dart
int count = 0;
do {
