[SOLVED] Segment Fault

[namerohit]

// I want to work with command line arguments //

This is the code thats giving 'Segmentation Fault':

int main(int argc, char * argv[ ] )
{


char * userName;
strcpy(userName, argv[2] );


char * objName;
strcpy(objName, argv[3] )

}


I understand here I attempt to point a read only memory blocks of argv, which was not allowed.

But I don't know how to make my way around. I want to copy the command line arguments (all the strings of argv ) to different variables (here I tried userName and objName pointers).

I don't want to create static arrays for storing them.
I even tried character-by-character copy... given in following code:

char * userName="";
char * objName="";

for(int i=2; i<=3; i++)
{
for(int j=0; j< strlen( argv[ i ] ); j++)
objName[ j ] = argv[ i ][ j ];

}

But even this does not work

Please help !
