Golang Program to Read a Number (n) and Compute (n+nn+nnn)
Let's read a number, n=5
Then, nn=55 and then nnn=555
res = 5 + 55 + 555 => 615
To read a number (n) and compute (n+nn+nnn), we can take the following
Steps
- Define a variable, n.
- Print a statement to get the number, n.
- Take user input for variable, n.
- Make an expression for (n + nn + nnn).
- Convert the expression into numbers.
- Compute the sum of the expression.
Example
package main
import (
"fmt"
"strconv"
)
func main(){
var n int
fmt.Print("Enter value of n: ")
fmt.Scanf("%d", &n)
t1 := fmt.Sprintf("%d", n)
t2 := fmt.Sprintf("+%d%d", n, n)
t3 := fmt.Sprintf("+%d%d%d", n, n, n)
exp := t1 + t2 + t3
fmt.Println("Expression is: ", exp)
n1, _ := strconv.Atoi(t1)
n2, _ := strconv.Atoi(t2)
n3, _ := strconv.Atoi(t3)
fmt.Println("Computed expression is: ", n1+n2+n3)
}Output
Enter value of n: 5 Expression is: 5+55+555 Computed expression is: 615
