Rust Program: Counting from 1 to 10
Rust Basic: Exercise-7 with Solution
Write a Rust program that counts from 1 to 10 using a loop and prints each number.
Sample Solution:
Rust Code:
fn main() {
// Initialize a variable to start counting from
let mut count = 1;
// Start a loop that runs until count reaches 11
while count <= 10 {
// Print the current value of count
println!("Count: {}", count);
// Increment count by 1
count += 1;
}
}
Output:
Count: 1 Count: 2 Count: 3 Count: 4 Count: 5 Count: 6 Count: 7 Count: 8 Count: 9 Count: 10
Explanation:
Here's a brief explanation of the above Rust code:
- fn main() { ... }: This is the entry point of the program, where execution begins.
- let mut count = 1;: This line declares a mutable variable named 'count' and initializes it with the value 1.
- while count <= 10 { ... }: This line starts a "while" loop. The loop will continue executing as long as the condition count <= 10 evaluates to 'true'.
- println!("Count: {}", count);: This line prints the current value of the 'count' variable using the println! macro. The {} is a placeholder for the value of 'count', which is provided as an argument to the println! macro.
- count += 1;: This line increments the value of the 'count' variable by 1. After each iteration of the loop, the value of 'count' will be increased by 1.
