In This Program you can use standard library function strlen() to find the length of a string but, this program computes the length of a string manually without using strlen() funtion.

Source Code to Calculate Length of a string without using strlen() Function

#include <iostream>
#include <cstring>
using namespace std;
int main()
{
    char s[1000],i;
    cout << "Enter a string: ";
    cin.getline(s, 1000);
    for(i=0; s[i]!='\0'; ++i);
    cout << "Length of string: " << i;
    return 0;
}
