Rust Program: Print length of strings

Last update on December 21 2024 10:22:28 (UTC/GMT +8 hours)

Write a Rust program that iterates over a vector of strings and prints the length of each string.

Sample Solution:

Rust Code:

fn main() {
    // Define a vector of strings
    let strings = vec!["Rust", "Exercises", "Examples", "Computer Programming"];

    // Iterate over each string in the vector
    for s in strings.iter() {
        // Print the length of each string
        println!("Length of '{}' is {}", s, s.len());
    }
}

Output:

Length of 'Rust' is 4
Length of 'Exercises' is 9
Length of 'Examples' is 8
Length of 'Computer Programming' is 20

Explanation:

In the exercise above,

• Define a vector 'strings' containing a list of strings.
• Use a "for" loop to iterate over each string in the vector.
• For each string 's', we print its length using the "len()" method.
