Expected output:

Concatenated string:

codeforhunger

  Step by step logic of the given program:

1. Accept two strings from user declare variables say str1 and str2.

2. Run while loop till end of first string:

while(*s1)

     {

  s1++;

3. Run while loop till end of second string and inside the while loop copy second string to first string:

while(*s2)

        {

*s1=*s2;

s1++;

s2++;

}

4. After that end first string with NULL(\0).

5. Last, print concatenated string str1.

printf("Enter second string:\n");

gets(str2);

while(*s1)/*till end of the first string*/

{

s1++;/*point to the next character*/

}

while(*s2)/*till end of the second string*/

{

*s1=*s2;

s1++;

s2++;
