def length(text):
counter = 0
for item in text:
counter += 1
return counter
Python
text = input("enter text : ")
count = 0
for i in text:
count += 1
print("string length = " , count)
tedad = 0
space = 0
string = input("please enter a string:" )
for i in string:
if i == " ":
space += 1
else:
tedad += 1
print(tedad)
Python
fun main() {
try {
println("Please Enter a series of words or numbers or signs as desired ")
val string1 = readln()
val length3 = stringToInt(string1)
println(length3)
} catch (e: Exception) {
println(e.message)
}
}
fun stringToInt(string1: String): Int {
val list1 = mutableListOf<Char>()
var number = 0
for (char in string1) {
list1.add(char)
number += 1
}
return number
}
Kotlin
def my_len(string):
"""
Calculate the length of a string manually
Arguments:
string: The string whose length we want to calculate
Return value:
string length
"""
count = 0
for char in string:
count += 1
return count
# Example of using the function
my_string = "hello world"
length = my_len(my_string)
print("string length:", length)
Python
String n;
int lowerCase = 0, upperCase = 0;
char currentChar;
Scanner input = new Scanner(System.in);
System.out.println("Enter a String : ");
n = input.nextLine();
for (int i = 0; i < n.length(); i++) {
currentChar = n.charAt(i);
if (Character.isLowerCase(currentChar)) {
lowerCase++;
} else if(Character.isUpperCase(currentChar)) {
upperCase++;
}
}
System.out.println("Lower Case is : " + lowerCase);
System.out.println("Upper Case is : " + upperCase);
