Adding a char to a string literal with C

I have defined a string literal as

char *name

and I want to add a char to name (the char is defined as char d = 'a').

I have tried

strcpy(name, d);

but when I try to print it I get a seg fault. How could I do this?

Solution

  • Use name[strlen(name)] = d.

    char *name = malloc(80);
// some code that puts something in *name
strcpy(name, "Hello World");
char d = 'a'
size_t len = strlen(name);
if (len >= (80-1)) DealWithNotEnoughRoom(); 
name[len++] = d;
name[len] = '\0';

    BTW:
    char *name is not a string literal. "Hello World" above is a string literal.
    char *name is a variable "name as pointer to char".
