[ error: expected an identifier ]

I am getting the following error using Visual Studio:

41 IntelliSense: expected an identifier

I have no idea what this is trying to say and any help would be appreciated! :D

Here is the program:

#include <stdio.h>
#include <math.h>

int
main(void)
{
         long long d;
     long long p;

     //Ask for numbers of days as long as input is not between 28 and 31

    do
    {
    printf("How may days are in your month?\n");
    d = GetInt();
    }
    while (d<28 || d>31);


    //Ask for numbers of pennies for day 1 as long as input is negative



    printf("How many pennies do you have");
    do
    {
        p = GetInt();
    }
    while ("p<0");


    //Sum up the pennies, pennies = (pennies*2)*2..*2

    int 1;
    for (i=0; i<= d-1; i++);
        {

            p=p*pow(2,i);
        }       
    printf("%lld\n", p);
    return 0;
}`

int 1;
for (i=0; i<= d-1; i++);

Here you have int 1; so the compiler is looking for a variable name such as int x = 1; Now the for loop, remove that ; from the end

inside the main the first two lines you have are

long long d;
long long p;

Here long is a type, so change those lines to

long d;
long p;

At the end of you file i see }', here remove the ' character

In addition, I can see you have while ("p<0"); as the while condition, here "p<0" is a string, you might want to change it to p<0.

You also probably want to replace

while ("p<0"); 

with

while(p<0);

(without the quotes).
