|
|
|
||
|
|
### Instructions
|
||
|
|
Create the following functions, that receives two parameters:
|
||
|
|
- sum, that returns the sum between two values from 0 to 255
|
||
|
|
- diff, that returns the difference between two values from -32768 to 32767
|
||
|
|
- pro, that returns the product of the multiplication between two values from -128 to 127
|
||
|
|
- quo, that returns the quotient of the division between two values
|
||
|
|
- rem, that returns the remainder of the division between two values
|
||
|

### Expected functions
|
||
|
|
|
||
|
|
```rust
|
||
|
|
pub fn sum(a:, b: ) -> {
|
||
|
|
|
||
|
|
}
|
||
|
|
|
||
|
|
pub fn diff(a: , b: ) -> {
|
||
|
|
|
||
|
|
}
|
||
|
|
|
||
|
|
pub fn pro(a: , b: ) -> {
|
||
|
|
|
||
|
|
}
|
||
|
|
|
||
|
|
pub fn quo(a: , b: ) -> {
|
||
|
|
|
||
|
|
}
|
||
|
|
|
||
|
|
pub fn rem(a: , b: ) -> {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage:
|
||
|
|
|
||
|
|
```rust
|
||
|
|
fn main() {
|
||
|
|
// sum
|
||
|
|
println!("sum : {}", sum(234, 2));
|
||
|
|
println!("sum : {}", sum(1, 255)); // 'ERROR: attempt to add with overflow'
|
||
|
|
// diff
|
||
|
|
println!("diff : {}", diff(234, 2));
|
||
|
|
println!("diff : {}", diff(-32768, 32766)); // 'ERROR: attempt to subtract with overflow'
|
||
|
|
// product
|
||
|
|
println!("pro : {}", pro(23, 2));
|
||
|
|
println!("pro : {}", pro(-128, 2)); // 'ERROR: attempt to multiply with overflow'
|
||
|
|
// quotient
|
||
|
|
println!("quo : {}", quo(22.0, 2.0));
|
||
|
|
println!("quo : {}", quo(-128.23, 2.0));
|
||
|
|
// remainder
|
||
|
|
println!("rem : {}", rem(22.0, 2.0));
|
||
|
|
println!("rem : {}", rem(-128.23, 2.0));
|
||
|
|
}
|
||
|
|
```
