Hey guys sorry for posting the whole code again.. How i can get my calenda program working from here? Because its not printing anything its only printing the mon tu wed etc but not the days of the month 1 - 31 and im not sure if its worked out correctly where the month starts? Someone plz help me? Code: int main(void) { unsigned month; unsigned year; unsigned long days = 0; int i; int *keeptrack; int daysOfMonth[MAX_MONTH] ={31,28,31,30,31,30,31,31,30,31,30,31}; /* that prints array for(i=0; i<MAX_MONTH; i++) { printf("days array:%d\n", daysOfMonth[MAX_MONTH]); }*/ month = getMonth(); year = getYear(); if(isLeapYear(year)) { daysOfMonth[1] = 29; /* change feb to 29 days*/ } displayCalendar(month, year, daysOfMonth, keeptrack); return EXIT_SUCCESS; } /***********************************track,***************************************** * Function getMonth() prompt the user for a number MIN_MONTH to MAX_MONTH and * returns that number.

The problem is your strtod function return 0 and so all the values are being lost. Use atoi instead of that as that can help you towards success.
