Write a program in C++ to find the length of a string without using the library function.
Pictorial Presentation:
Sample Solution:-
C++ Code :
#include <iostream>
#include <string>
using namespace std;
int main()
{
char str1[50];
int i, l = 0;
cout << "\n\n Find the length of a string:\n";
cout << "---------------------------------\n";
cout << " Input a string: ";
cin >> str1;
for (i = 0; str1[i] != '\0'; i++) {
l++;
}
cout << "The string contains " << l << " number of characters." << endl;
cout << "So, the length of the string " << str1 << " is:" << l << endl;
}
Sample Output:
Find the length of a string: --------------------------------- Input a string: w3resource.com The string contains 14 number of characters. So, the length of the string w3resource.com is:14
