This section contains the Golang basics find output programs (set 4) with their output and explanations.
Program 1:
package main
import "fmt"
func main() {
var num1 int = 0
var num2 int = 0
fmt.Print("Enter the value of num1 and num2: ")
fmt.Scanf("%d%d", num1, num2)
fmt.Println("Addition is: ", num1+num2)
}
Program 2:
package main
import "fmt"
func main() {
var num1 int = 0
var num2 int = 0
var num3 int = 0
fmt.Print("Enter the value of num1 and num2: ")
num3 = fmt.Scanf("%d%d", &num1, &num2)
fmt.Println("Num1: ", num1)
fmt.Println("Num2: ", num2)
fmt.Println("Num3: ", num3)
}
Program 3:
package main
import "fmt"
func main() {
var num1 int = 0
var num2 int = 0
var num3 int = 0
fmt.Print("Enter the value of num1 and num2: ")
num3, _ = fmt.Scanf("%d%d", &num1, &num2)
fmt.Println("Num1: ", num1)
fmt.Println("Num2: ", num2)
fmt.Println("Num3: ", num3)
}
Program 4:
package main
import "fmt"
func main() {
var str string
fmt.Print("Enter string: ")
fmt.Scanf("%s", str)
fmt.Println(str)
}
Program 5:
package main
import "fmt"
func main() {
var str string
fmt.Print("Enter string: ")
fmt.Scanf(&str)
fmt.Println(str)
}
Go programming
Answer Program 1:
Output:
Explanation:
In the above program, we read the value of num1 and num2 variables using fmt.Scanf() function but here we did not use the "&" operator to assign input value to the variables that why addition is 0.
Answer Program 2:
Output:
Explanation:
The above program will generate a syntax error. Because fmt.Scanf() function returns two values but we used only the num3 variable as an lvalue.
Answer Program 3:
Output:
Explanation:
In the above program, we created three variables num1, num2, and num3. The fmt.Scanf() function returns the total number of variables read from the user. Then we printed the values of all variables.
Answer Program 4:
Output:
Explanation:
The above program will not print the input string because while taking an input need to use the "&" operator.
Answer Program 5:
Output:
Explanation:
The above program will generate a syntax error. Because we cannot use fmt.Scanf() function without specifying format specifiers.
