Feb 24, 2015 · The fundamental difference is that in one char* you are assigning it to a pointer, which is a variable. In char[] you are assigning it to an array which is not a variable. char[] is a structure, it is specific section of memory, it allows for things like indexing, but it always will start at the address that currently holds 'h'. char* is a ...

Well, a string is just an array of chars that terminates with a the a '\0' (which is of course a char by itself). Array elements are stored in contiguous places in memory. The address of an array (the whole memory block), whether that's a string or just a regular char array, is the same as the address of the first byte in the array which is ...

char *s = "hello"; basically an array of chars is created for you and is initialized with the contents of the string literal (in this case, "hello"). The address of the location, where this array is stored, is then stored into s.

Jan 29, 2016 · For most purposes you probably won't experience any differences between the 2, but the difference is that declaring an array such as char buffer[n] results in memory on the stack being allocated. Stack memory is smaller, and is cleared after the function returns; so if you need to retain buffer, or if buffer is so large as to exceed stack ...

Jan 28, 2021 · Exactly. But, let's clarify something. When a string (a char array) is allocated, the memory is indeed allocated. If a string of length 10 is declared, 10 bytes are allocated in stack memory for that string variable. Memory isn't allocated when chars are later assigned, the memory is allocated when the var is declared. –

then access the contents of that string like you'd do with a char array. For example, if I wanna print out the first char in that string I may have something like this: printf("%c\n", s[0]); Second, assuming you're using a char array for any reason, you don't have to cast the char you're accessing to a char since it's already a char! So ...

The previous function takes 3 arguments, the array from which you wanna extract the first n elements (i.e., srcArray), the array to which you wanna extract these elements (i.e., subArray) and the number of elements to be extracted (i.e., n).

Jul 4, 2014 · scanf("%d\n", array); is executed, scanf() expects to read an int followed by any amount of white-spaces (e.g., space, tab, newline, etc) including none at all. Since you specified a newline character in the format and since \n means any amount of white-spaces (including none), scanf() continues reading after the first newline looking for more ...

Oct 19, 2016 · Then if I want to link the list together in this array, could I loop through 0 -10 and for 1 through 9 do something like: ptrArray[i]->next = ptrArray[i+1]; It seems like I should be able to because the array just has pointers to structs and I'm just adding one. Now let's say I want to print these guys. Is it as simple as

Very similar code also works for traversing through a char array, no need to use the sizeof function ...
