25Ramco25Systems

The output will b : RamcoSystems

the output will be RamcoSystems
but we need 2 more libraries
#include<string.h> and
#include<alloc.h>
to run this program. in else case it will not work.

#include<stdio.h>

main()
{
        char *p1,*p2;
        p1 = (char *)malloc(25);
        p2 = (char *)malloc(25);
        strcpy(p1,"Ramco");
        strcpy(p2,"Systems");
        strcat(p1,p2);
        printf("%s",p1);
}



the output will be RamcoSystems

we don't need the following libraries under Linux 2.6
#include<string.h> and
#include<alloc.h>
to run this program.

The program is not correct. What is present in memory 
beyond "Ramco" is not known and we are trying to 
attach "Systems". May be we are overwriting something which 
is unsafe.

To concatenate two strings declare the first as array.

example: char p1[50];
char *p2;
p2 = malloc(25);
strcpy(p1, "Ramco");
strcpy(p2,"Systems");
strcat(p1,p2);
