a:** b: c: ... ... x:* y:** z:* 

your printf call missing format argument, have this:

printf("%d:%c\n",print_star(char_count[i]),'a'+ i); 

but passing 2 arguments printf, far can tell meant:

printf("%d:%c\n",print_star(char_count[i]),'a'+ i); 

also, print_star has return value of int not have return statement, think meant return i , in case should add:

return ; 

at end. behavior without return @ end undefined. finally, looks have typo in forward declaration, this:

int print_fun(int); 

should be:

int print_star(int value );
