(C PROGRAM IN VISUAL STUDIO) Calendar Program. 1 small addition.

All i want help with is changing the number value I enter in scanf such as 1 = January, 2 = February, etc. The code works fine as is and everything Just want the month name to display in the header as opposed to the number of the month. Code is below.

Code:

#define _CRT_SECURE_NO_WARNINGS#include <stdio.h> int getdaycode(int month, int year); void printheader(int month, int year); int getndim(int month, int year); int main(void) { int day, month, year, nummonths; printf("Enter Month, Year, and number of Months: "); if (scanf("%d %d %d", &month, &year, &nummonths) != 3 || year < 0 || month < 1 || month > 12) { printf("invalid input\n"); return 1; } for (int i = 0; i < nummonths; i++) { printheader(month, year); int numdays = getndim(month, year); int daycode = getdaycode(month, year); printf("%*s", daycode * 4, ""); /* print 4 spaces for each skipped day */ for (day = 1; day <= numdays; day++) { printf("%3d", day); daycode = (daycode + 1) % 7; if (daycode != 0) printf(" "); else printf("\n"); } if (daycode != 0) printf("\n"); printf("\n"); month = month + 1; if (month > 12) { month -= 12; year += 1; } } return 0; } int getdaycode(int month, int year) { int numdays; { numdays = ((year - 1) * 365 + ((year - 1) / 4) - ((year - 1) / 100) + ((year - 1) / 400)); // how many days including exceptions if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)) //check if leapyear { if (month == 1) // January numdays = numdays; if (month == 2) // February numdays = numdays + 31; if (month == 3) // March numdays = numdays + 28 + 31 + 1; if (month == 4) // April numdays = numdays + 31 + 28 + 31 + 1; if (month == 5) // May numdays = numdays + 30 + 31 + 28 + 31 + 1; if (month == 6) // June numdays = numdays + 31 + 30 + 31 + 28 + 31 + 1; if (month == 7) // July numdays = numdays + 30 + 31 + 30 + 31 + 28 + 31 + 1; if (month == 8) // August numdays = numdays + 31 + 30 + 31 + 30 + 31 + 28 + 31 + 1; if (month == 9) // September numdays = numdays + 31 + 31 + 30 + 31 + 30 + 31 + 28 + 31 + 1; if (month == 10) // October numdays = numdays + 30 + 31 + 31 + 30 + 31 + 30 + 31 + 28 + 31 + 1; if (month == 11) // November numdays = numdays + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 31 + 28 + 31 + 1; if (month == 12) // December numdays = numdays + 30 + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 31 + 28 + 31 + 1; } else { if (month == 1) // January numdays = numdays; if (month == 2) // February numdays = numdays + 31; if (month == 3) // March numdays = numdays + 28 + 31; if (month == 4) // April numdays = numdays + 31 + 28 + 31; if (month == 5) // May numdays = numdays + 30 + 31 + 28 + 31; if (month == 6) // June numdays = numdays + 31 + 30 + 31 + 28 + 31; if (month == 7) // July numdays = numdays + 30 + 31 + 30 + 31 + 28 + 31; if (month == 8) // August numdays = numdays + 31 + 30 + 31 + 30 + 31 + 28 + 31; if (month == 9) // September numdays = numdays + 31 + 31 + 30 + 31 + 30 + 31 + 28 + 31; if (month == 10) // October numdays = numdays + 30 + 31 + 31 + 30 + 31 + 30 + 31 + 28 + 31; if (month == 11) // November numdays = numdays + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 31 + 28 + 31; if (month == 12) // December numdays = numdays + 30 + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 31 + 28 + 31; } } int daycode = (numdays + 1) % 7; return daycode; } void printheader(int month, int year) { printf("%14d %1d\n", month, year); printf("Sun "); printf("Mon "); printf("Tue "); printf("Wed "); printf("Thu "); printf("Fri "); printf("Sat\n"); } int getndim(int month, int year) { int numdays; if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)) //check if leapyear { if (month == 1) // January numdays = 31; if (month == 2) // February numdays = 29; if (month == 3) // March numdays = 31; if (month == 4) // April numdays = 30; if (month == 5) // May numdays = 31; if (month == 6) // June numdays = 30; if (month == 7) // July numdays = 31; if (month == 8) // August numdays = 31; if (month == 9) // September numdays = 30; if (month == 10) // October numdays = 31; if (month == 11) // November numdays = 30; if (month == 12) // December numdays = 31; } else { if (month == 1) // January numdays = 31; if (month == 2) // February numdays = 28; if (month == 3) // March numdays = 31; if (month == 4) // April numdays = 30; if (month == 5) // May numdays = 31; if (month == 6) // June numdays = 30; if (month == 7) // July numdays = 31; if (month == 8) // August numdays = 31; if (month == 9) // September numdays = 30; if (month == 10) // October numdays = 31; if (month == 11) // November numdays = 30; if (month == 12) // December numdays = 31; } return numdays; }

You can create an array of strings (each value corresponding the month name).

The indexes will then serve as a representation for the month that you pass in to your header function.

Do you think something like this could work maybe in my printheader function?

Code:

int daycode = numdays % 7; switch (daycode) { case 0: printf("Sunday\n"); break; case 1: printf("Monday\n"); break; case 2: printf("Tuesday\n"); break; case 3: printf("Wednesday\n"); break; case 4: printf("Thursday\n"); break; case 5: printf("Friday\n"); break; case 6: printf("Saturday\n"); break; default: printf("unexpected error (daycode case) daycode = %d", daycode); break; } return daycode; }

But with months

Try it and see.

And cross-posting is considered poor etiquette.

How To Ask Questions The Smart Way

Ok, I didn't know what thanks for letting me know.

Note that your program (if you fix the bugs) will only work back to Sep 14, 1752.
