In c language(strings) can we combine two strings by statement s3=s1+s2 if they are declaired as *s1,*s2,*s3?

The std::string class already overloads operator+() to allow string concatenation. But as you have declared your variables as pointers to strings, you need to dereference them before you can do this.


std::string *s1,*s2,*s3;


//


*s3 = (*s1)+(*s2) rather than s3=s1+s2





Now, do the rest of your homework yourself. All you have to do is type the damn things into a C interpreter.

no you cant, you can you apply addition operation on two strings ? be logical !





you can try the below code for string concatenation





#include%26lt;string.h%26gt;


#include%26lt;conio.h%26gt;


#include%26lt;stdio.h%26gt;


void main()


{


char s1[10],s2[10];


printf("\n enter string 1");


gets(s1);


printf("\n enter string 2");


gets(s2);


strcat(s1,s2);


puts(s1);


getch();


}
Reply:Nope.... Ucan use strcat(); function to concatenate two strings.....Go to help page of strcat() function to find how to use parameters for that function as per your needs.


U can use + to concatenate strings only using Operator Overloading (polymorphism Feature) which can be used in Object Oriented Programs like C++...
