The concept of a string in C is difficult, because a string is a collection of characters stored in memory terminated by a NULL string i.e. \0. Let us consider the string Hello. This occupies 6 addresses in memory i.e.
4000 H 4001 e 4002 l 4003 l 4004 o 4005 \0 Therefore in order to declare a string in C we really declare a pointer to the string and C will stop reading in the string when it reaches the NULL terminator. Consider the program which prints your name
#include stdio.h void main() { char prompt; /*Author : Mr James Mc Carren Company: Staffordshire University Date: 26th August 2012 Version 1.0 Function : String storing illegally Modifications: none*/ char *name; name = "James Mc carren"; printf("your name is %s \n\r",name); printf("Press and key to exit \n\r"); scanf("\n%c",&prompt); } Care should be taken with Loading up pointers as C needs to allocate space to any variable. The statement name = "James Mc carren"; allocates 16 spaces. Consider the following program #include void main() { char prompt; /*Author : Mr James Mc Carren Company: Staffordshire University Date: 26th August 2012 Version 1.0 Function : String storing illegally Modifications: none*/ char *name; scanf("%s",name); printf("your name is %s \n\r",name); printf("Press and key to exit \n\r"); scanf("\n%c",&prompt); }
