Thread: Error check date loop code

Code:

void getDate(Car_t fleet[], int z, char dateType) /*Function that gets the date from the user*/
{
    int day, month, year;
    /*put a loop here to error check*/
    if(dateType = 'm')
    printf("Please enter manufacture date in dd/mm/yyyy format> ");
    else if (dateType = 'p')
    printf("Please enter purchase date in dd/mm/yyyy format> ");
    else
    printf("Error, unknown date format\n");
    scanf("%d/%d/%d", &day, &month, &year);
    /*end loop here*/

I need to use a loop in the there, which will check the dates are in range from 1-31, months are from 1-12, and year from 1900-2012, otherwise it will ask again. Tried a while loop but gets very complicated and then the function does not work anymore. Can someone help please?

So in the while part i would write?

Code:

while(day>0 && day <32, month>0 && month<13, year>1899 && year<2013)

Is that correct?

I did. It does not work i think, it still accepts dates like 35 .

Here is the code

Code:

void getDate(Car_t fleet[], int z, char dateType) /*Function that gets the date from the user*/{
    int day, month, year;
    do
    {
        if(dateType == 'm')
        printf("Please enter manufacture date in dd/mm/yyyy format> ");
        else if (dateType == 'p')
        printf("Please enter purchase date in dd/mm/yyyy format> ");
        else
        printf("Error, unknown date format\n");
        scanf("%d/%d/%d", &day, &month, &year);
    }while(day>0 && day<32 && month>0 && month<13 && year>1899 && year<2013);

It works with both valid and invalid dates now.
