strings
Find the length of the string using the function strlen
from the <string.h> library.
Algorithm implementation
Declare the character array.
char s[110];
Read the input string.
gets(s);
Print the input string.
puts(s);
Print the length of the input
string.
printf("%d\n",strlen(s));
Algorithm implementation
– C++
Read the input string.
getline(cin, s);
Print the input string.
cout << s << endl;
Print the length of the input
string.
cout << s.length() << endl;
Algorithm implementation
– dynamic array
#include <stdio.h>
char *s;
void puts(char *s)
{
while(*s)
printf("%c",*s++);
printf("\n");
}
int strlen(char *s)
{
int len = 0;
while(*s++) len++;
return len;
}
int main(void)
{
s = new char[110];
gets(s);
puts(s);
printf("%d\n",strlen(s));
delete[] s;
return 0;
}
Java implementation
import
java.util.*;
public class Main
{
public static void main(String[] args)
{
Scanner con = new Scanner(System.in);
String s = con.nextLine();
System.out.println(s);
System.out.println(s.length());
con.close();
}
}
Python implementation
Read the input string.
a = input()
Print the input string.
print(a)
Print the length of the input
string.
print(len(a))
