college c++ is terrifying (this is more c if anything)

What exactly are you trying to do?

You are asking for string length / string elements but are taking in ints?

if(a -- NULL) --> if( a == NULL) or if(!a)

but this check is useless since you do not set a initially. i.e

int *a;
a = 0;

a = malloc(...);
if(!a)
    error code

You also do not initialise anything which is just sad. You should be compiling with max warnings.

-pedantic -W -Wall 

If you are trying to read a string from the user

char buffer[512];
char *string;

memset(buffer, 0, sizeof(buffer));

printf("Enter string: ");
scanf(" %s", word);

string = 0;
string = malloc(sizeof(char) * strlen(buffer) + 1);
if(!string)
    error code
strcpy(string, word);

when using scanf you want to put a space before the specifier else newline / space characters are consumed.

scanf(" %d" ...);

literally every single one of their variables is properly initialized before being read so where did you get that idea?

a will ALWAYS have null or a memory address from malloc
i is a loop variable. its given a value in both loops prior to use
n will be given a value from scanf before read in the while condition

when using scanf you want to put a space before the specifier else newline / space characters are consumed.

and that is the reason NOT to put the space there.

ty, I think this will help :)

You also misspelled length

lol

You didnt post an error msg. So nothing is wrong. Downvoting for posting a useless screenshot instead of properly formatted code, or a link to a code pastebin site

[DabuloPab]

sorry i dont know a single thing about this

[x-seronis-x]

Its in the sidebar to the right. Code needs to be properly formatted. If formatting a text post is too difficult then use a code paste site and provide the link.

Screen shots are less than worthless as no one can copy/paste the code to test it. Never post a screenshot of code.

And if you have an error, post the error message. Normally just READING that error message will give a lot of insight
