C Exercises: Return the number of clumps in a given array

C Array: Exercise-100 with Solution

Write a program in C to return the number of clumps (a series of 2 or more adjacent elements of the same value) in a given array.

Sample Solution:

C Code:

#include<stdio.h> 

int countClumps(int arr1[], int m) 
{
  int l = m;
  int current = -1, clump = 0;
  for(int i = 0; i < l - 1; i++) 
  {
    if(arr1[i] == arr1[i + 1] && arr1[i] != current) 
	{
       current = arr1[i];
       clump++;
    } 
	else 
	{
       if(arr1[i] != current) 
	   {
          current = -1;
       }
    }
  }
  return clump;
}
int main() 
{ 
    int arr1[] = {17, 42, 42, 7, 24, 24, 17, 54, 17}; 
    int arr_size = sizeof(arr1)/sizeof(arr1[0]); 
    int i = 0; 
   //------------- print original array ------------------	
	printf("The given array is:  \n");
	for(i = 0; i < arr_size; i++)
		{
			printf("%d  ", arr1[i]);
		}
	printf("\n");
//-----------------------------------------------------------    
    printf("The number of clumps in the array is:  %d", countClumps(arr1,arr_size)); 
    return 0; 
}

Sample Output:

The given array is:  
17  42  42  7  24  24  17  54  17  
The number of clumps in the array is:  2

C Programming: Tips of the Day

C Programming - What is the argument for printf that formats a long?

Put an l (lowercased letter L) directly before the specifier.

unsigned long n;
long m;

printf("%lu %ld", n, m);
