Pset 1 expected expression

Question

I've run into a problem on credit. Whenever I run this

#include <stdio.h>
#include <cs50.h>

int main(void)
{
    int credit;

    //Ask user for input of cc number

    printf("What is your creditcard number?");
    credit = get_long_long();

    //See if number is long enough
    if ( int credit > 100000000000 && int credit < 10000000000000000 ) {
        printf("Hallelujah\n");
    }
    else {
        printf("Nope\n");
    }

}

block of code I get the error:

creditcard.c:14:10: error: expected expression
    if ( int credit > 100000000000 && int credit < 10000000000000000 ) {
         ^
1 error generated.
make: *** [creditcard] Error 1

I checked other questions discussing the same error message, none seem to help me with mine though.

Answer 1

if ( int credit > 100000000000 && int credit < 10000000000000000 ) 

When we declare int credit again, within IF, we are really declaring a new variable, different from the first credit outside and with a scope only within the IF block, the solution would be to eliminate the int. But I have to tell you that this will not solve your problems, values to which perform comparison is outside the range that can be stored in an integer. You can check this by simply changing your numbers to smaller ones, such as 10 and 100
