$ g++ LevenshteinDist.cpp $ a.out the Levinstein distance is 9 ------------------ (program exited with code: 0) Press return to continue
Here is source code of the C++ Program to Implement Levenshtein Distance Computing Algorithm. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.
#include <stdio.h>
#include <math.h>
#include <string.h>

int main()

char s[] = "Sanfoundry";
char t[] = "Education";
m = strlen(s);
