printf("\nConcatenate the String at Str 1 with the use of Logic\n\n");

while(1)
{
if(str1[i]!=NULL)
{
i=i+1;
continue;
}

str1[i]=str2[j];
i=i+1;
j=j+1;

if(str2[j]==NULL)
break;
}
str1[i]=NULL;
printf("String 1 is \n\n");
puts(str1);

printf("\n Concatenate with the use of function strcat()");
strcat(str1,str2);
printf("\n Content of Str 1 :");
puts(str1);

getch();
}

Output:

* Program will join two string without using function.
