C String Join

In this section, you will learn how to join the strings. You can see in the given example, we have define two strings and initializes two integer variables length1 and length2 to 0. Then consider the length1 as the length of the string s1 and length2 as the length of string s2.
Now set the length2 to 0 and by using while loop equate the two strings. Finally, the string st1 joins to st2.

Here is the code:

STRINGJO.C


#include <stdio.h>

#include <conio.h>

int main() {

  char s1[40] = "WEL";

  char s2[] = "COME";

  int length1 = 0;

  int length2 = 0;

  while (s1[length1])

    length1++;

  while (s2[length2])

    length2++;

  length2 = 0;

  while (s2[length2]) {

    s1[length1++] = s2[length2++];

  }

  printf("\n%s\n", s1);

  getch();

  return 0;

}

Output will be displayed as:

STRINGJO.EXE
