C Exercises: Segregate 0s and 1s in an array

C Array: Exercise-95 with Solution

Write a program in C to segregate 0s and 1s in an array.

Sample Solution:

C Code:

#include <stdio.h> 
  
void segZeroAndOne(int arr1[], int n) 
{ 
    int ctr = 0; 
  
    for (int i = 0; i < n; i++) { 
        if (arr1[i] == 0) 
            ctr++; 
    } 
    for (int i = 0; i < ctr; i++) 
        arr1[i] = 0; 
  
    for (int i = ctr; i < n; i++) 
        arr1[i] = 1; 
} 
void printSegre(int arr1[], int n) 
{ 
    printf("The array after segregation is: "); 
    for (int i = 0; i < n; i++) 
        printf("%d  ",arr1[i]); 
} 
int main() 
{ 
    int arr1[] = { 1, 0, 1, 0, 0, 1, 0, 1, 1 }; 
    int n = sizeof(arr1) / sizeof(arr1[0]); 
	int i;
   //------------- print original array ------------------	
	printf("The given array is:  \n");
	for(i = 0; i < n; i++)
		{
			printf("%d  ", arr1[i]);
		}
	printf("\n");
//-----------------------------------------------------------      
    segZeroAndOne(arr1, n); 
    printSegre(arr1, n); 
      
    return 0; 
} 

Sample Output:

The given array is:  
1  0  1  0  0  1  0  1  1  
The array after segregation is: 0  0  0  0  1  1  1  1  1
