Hello, i have just to work with pointers and this code is in the example in my book but it crash when i compile it.

  #include <stdio.h>


int main(void) {

    int i = 2;
    int *p;
    p=&i;
    *p=3;
    printf('Ahora i = %d \n', i);

    
    return(0);
}

this is the error logout

'single quotes' are for character literals
"double quotes" are for string literals

put your string in double quotes, not single quotes.
