Question

C Programming

2) Write a function that removes the redundant values from the array and replaces them with -1

Example: A = {4, 1, 2, 3, 4, 4, 5, 6, 2, 7}

The array becomes: A = {4, 1, 2, 3, -1, -1, 6, -1, 7}

Answer 1

Coding

#include <stdio.h>//standard input output header file
#define size 10//define size here for array size
void redudent(int []);
int main()
{
     int arr[size]={4, 1, 2, 3, 4, 4, 5, 6, 2, 7},i;//declare variable here
   printf("print array before removing redudent \n");//output display message
   for(i=0;i<size;i++)
   {
   printf("%d ",arr[i]);//dispaly array
   }
   printf("\n");
   redudent(arr);
     return 0;
}
void redudent(int a[])
{
   int i,j;//declare variable
   //here is the removing redudent data
   for(i=0;i<size;i++)
   {
       int temp=a[i];
       for(j=i+1;j<size;j++)
       {
           if(temp==a[j])
           a[j]=-1;
       }
   }
   printf("print array after removing redudent \n");//output display message
   for(i=0;i<size;i++)
   {
   printf("%d ",a[i]);//dispaly array
   }
}

output:
