// this program is to contenate strings without using string function

#include <stdio.h>
#include <string.h>

void concatenate(char *str1, char *str2)
{
    int i = strlen(str1), j = 0;

    while (str2[j] != '\0')
    {
        str1[i] = str2[j];
        i++;
        j++;
    }

    str1[i] = '\0';  // declaring the end of the string
}

int main()
{
  char string1[20], string2[20];
  gets(string1);
  gets(string2);
  
  concatenate(string1, string2);
