char problem in C

[Seko]

i have a char array: char x[20];
i did the following: strcpy(x, argv[2]);

but i want to add one space in the begining and end of the char array for example say argv[2] is "abc" so i want x to contain " abc " how can i do this?

thx

[Minime80]

this should pretty much do it

char x[20];
strcpy(x, " ");
strcat(x, argv[2]);
strcat(x, " ");

Anytime. We're here to help.

another way to do that:

int x[20];  
sprintf(x," %s ",argv[2]);

[dchidelf]

or

char x[20];
sprintf(x," %.17s ",argv[2]);

That should ensure the string will actually fit within the allocated space.

Or

char x[20];

snprintf(x, 20, " %s ", argv[2]);

(another way to not overflow the buffer).
