Pictorial Presentation:

Read month number and display number of days for that month

Sample Solution:

C Code:

#include <stdio.h>
void main()
{
   int monno;
   char monnm[15];

   scanf("%d",&monno);
   switch(monno)
   {
	case 1:
	case 3:
	case 5:
	case 7:
	case 8:
	case 10:
	case 12:
	       printf("Month have 31 days. \n");

C Programming: Tips of the Day

Why do C and C++ compilers allow array lengths in function signatures when they're never enforced?

It is a quirk of the syntax for passing arrays to functions.

Actually it is not possible to pass an array in C. If you write syntax that looks like it should pass the array, what actually happens is that a pointer to the first element of the array is passed instead.

Since the pointer does not include any length information, the contents of your [] in the function formal parameter list are actually ignored.
