As memory is not allocated for pName in structure. Program will crash. Source: CoolInterview.com

Program crashes when it comes to strcpy() line. Since memory allocation is done for structure, not for the pointer(char *pName) inside the structure. Source: CoolInterview.com

we get segmentation fault bcoz strcpy() function can't allocate memory and struct is for memory allocation so there is no need of malloc when the variable is declared in struct. Source: CoolInterview.com
