Rust | convert an unsigned integer into a signed integer: Given an unsigned integer and we have to convert it into the signed integer.
Submitted by Nidhi, on October 08, 2021

Problem Solution:

In this program, we will create an unsigned integer variable then we will assign the value of the unsigned integer variable by converting it into a signed integer variable using the "as" keyword.

Program/Source Code:

The source code to convert an unsigned integer into a signed integer is given below. The given program is compiled and executed successfully.

// Rust program to convert an unsigned 
// integer into a signed integer

fn main() 
{
    let mut UintVar:u8 = 123;
    let mut intVar:i8 = 0;
    
    intVar=UintVar as i8;
    println!("Signed integer is : {}",intVar);
}

Output:

Signed integer is : 123

Explanation:

Here, we created a variable UintVar of the u8 type. Then we assigned the value of the UintVar variable into the i8 variable using the "as" keyword. After that, we printed the result.
