Case 1 : Enter an array or string : 1020304050 Length of the string is : 10 Case 2 : Enter an array or string : hello Length of the string is : 5 Case 3: Enter an array or string : Program25 Length of the string is : 9
This is a C++ Program to Find the Length of a String/Array.
The program takes a string or an array and prints its length.
1. The program takes a string or an array.
2. Using inbuilt function, the length of the string is found.
3. The result is printed.
4. Exit.
Here is the source code of C++ Program to Find the Length of a String/Array. The program output is shown below.
#include<iostream>
#include<string.h>
using namespace std;
int main ()
{
char str[50];
int len;
cout << "Enter an array or string : ";
gets(str);
len = strlen(str);
cout << "Length of the string is : " << len;
return 0;
}
1. The user is asked to enter an array or a string and it is stored in the character variable ‘str’.
2. Using the function strlen() which is inbuilt under the library ‘string.h’, length of the string is found.
3. The result is then printed.
Case 1 : Enter an array or string : 1020304050 Length of the string is : 10 Case 2 : Enter an array or string : hello Length of the string is : 5 Case 3: Enter an array or string : Program25 Length of the string is : 9
