✐ Examples

1 Check if String contains specific Character using loop

In this example,

We create a function 'containsCharacter' that takes a string and a character as input.
We loop through each character in the string and check if it matches the target character.
If a match is found, we return 'true'; otherwise, 'false'.
Finally, we print the result.

Go Program

package main
import (
    "fmt"
)

func containsCharacter(str string, ch rune) bool {
    for _, char := range str {
        if char == ch {
            return true
        }
    }
    return false
}

func main() {
    str := "Hello World"
    ch := 'W'
    contains := containsCharacter(str, ch)
    fmt.Printf("String contains character '%c': %t\n", ch, contains)
}

Output

String contains character 'W': true
